Hacker News Jobs

We build authority infrastructure for people whose expertise has outgrown their digital presence — founders, scientists, operators. Positioning and narrative first, then the sites, content pipelines and distribution that make it compound. The delivery layer is agentic: Claude Code, Cursor and Aider doing the build work, humans holding editorial judgement and the client relationship. Engagements are scoped rather than staffed by the hour, so the work is contract and senior-weighted.

Open now:

- Sr Agentic Engineer — Claude Code / Cursor / Aider across the FM stack: member site infrastructure, content automation pipelines. TypeScript, system architecture, comfortable scoping a problem before writing code.

- AI-Native Tech & Growth Director — owns the platform and the agentic build system behind member launches. 8+ years technology leadership.

- Agentic Operations Coordinator — the bridge between strategy and build: Claude Code site builds, prompt development and tool evaluation, SEO and distribution testing.

Also open: brand strategy, editorial production, PR, design and copywriting.

Do you feel scared and alone when opening the AWS console? Do you wish you could just tell Claude to manage your infra, and it would just work? Do you dream of a future where software is abundant and developers and normies alike are free to build their wildest dreams?

We're Railway, and we think infrastructure can be better. We're working at the forefront distributed systems engineering, interface design, and agentic computing to bring about the infrastructure platform we've always wanted. So far we've built out a platform loved by 3M+ users and we're just getting started.

Fair warning! The problems are complex: racking and stacking servers, home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.

Hi HN,

I’m the founder of Proxybase [0]. We’re building an agentic SOCKS5 proxy network designed to bring transparency and ethical sourcing to the residential proxy market.

Quick note to anyone who applied last month: First off, thank you to everyone who reached out. We got hit with way more high-quality applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to respond than we should have. If you applied last month and haven't heard back, we're genuinely sorry for the delay, we are actively reviewing those responses alongside this batch.

Why Proxybase? Historically, the residential proxy industry has been pretty shady, think hidden background scrapers bundled into TV firmware or mobile apps, combined with predatory payout systems that hold provider funds hostage for months.

We’re taking a different approach:

Fully Open-Source Clients: Our GUI [1] and CLI [2] are completely open-source so anyone can inspect and audit what we run. Explicit Consent: Providers knowingly opt in. No stealth bundling. Instant, Fair Payouts: $1 minimum payout threshold sent directly to provider wallets via US stablecoins—no holding funds to farm interest.

What We’re Looking For We’re looking for a Backend Systems Engineer (Rust) to help us build out our asynchronous SOCKS5 routing infrastructure, daemon node orchestration, and automated bandwidth allocation pipelines.

Stack: Rust (Tokio / Axum), SOCKS5 protocol, Linux systemd daemons, SQLite Location: Fully Remote (Async-friendly, flexible timezone) Compensation: Competitive salary + equity (USD or stablecoin options available)

If you're interested in building infrastructure for an industry that desperately needs better standards, send an email to jobs@proxybase.xyz with your GitHub/resume and a short note on what you’ve been working on lately.

I’m also around in the comments if you have any questions or feedback on what we're building.

We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely love to do. We’re obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.

Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests. Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.

Tessellate is pre-seed and early — this is a real chance to help build a startup from the ground floor, led by second-time founders. There are genuinely hard, interesting data challenges under the hood that push us to lean into AI and machine learning as part of the product itself. We expect our engineers to be AI-native: using the most advanced AI and cloud tooling to ship quality software at pace. Startups aren't for everyone — but you'll learn a great deal, own outcomes that matter, and share in the upside if we win.

We're hiring an associate to mid-level product engineer to build alongside our small team and ship features across the product — from a mobile-first frontend through the Python API and the data beneath it. This is a build-and-ship role: your week is spent turning product ideas into working, tested, shipped features that physicians use.

You won't be alone at the edges. We have fractional senior support for our infrastructure and a dedicated data engineer for the claims layer, so you can lean on real depth where you need it and stay focused on moving the product forward. What we need from you is momentum on the product itself.

$100K - $130K apply at https://jobs.gem.com/tessellate/am9icG9zdDrOWl6wmQoqG4beEY9k...

Tessellate | Senior ML Data Engineer | Hybrid | Nashville, TN | Full-time

Tessellate is pre-seed and early — this is a real chance to help build a startup from the ground floor, led by second-time founders. There are genuinely hard, interesting data challenges under the hood that push us to lean into AI and machine learning as part of the product itself.

Physicians make some of the biggest decisions of their careers with almost no trustworthy information: job posts, recruiter calls, and vague promises about culture. Tessellate is building something better: a physician-first platform that helps doctors see where they'd actually fit, using real clinical data instead of recruiter intuition.

At the center of the product is a matching engine that pairs physicians with organizations. Making it genuinely intelligent is your job.

Our matching engine works today, but it's mostly rules and weights. Over the next year we want to make it genuinely smart; real semantic matching and vector search over physicians, organizations, and clinical profiles - with the rigor to actually measure whether it's getting better. That's the heart of this role.

Two things make it hard. The matching is only as good as the identity underneath it: if one health system shows up as three fragmented records, you get three bad embeddings instead of one good one. And healthcare data is a mess, fragmented across sources that don't agree, so reasoning about fit from it is a genuinely deep problem.

Connie Health is a fast-growing Medicare brokerage on a mission to empower older Americans to make confident, worry-free Medicare plan decisions.

We are looking for a Senior Analytics Engineer to own our data transformation layer end-to-end. You will build the clean, well-modeled, documented datasets that the entire company relies on, spanning board-level book-of-business reporting (policy count, retention, effectuation, commissions), stakeholder self-service through Looker, and AI-driven exploration through tools like Claude. This is a high-leverage senior IC role: the quality of our analytics, forecasts, and operating decisions all depend on the foundation you build. You'll partner directly with Engineering, Finance, and Operations to fix data quality at the source, not downstream.

Tech stack: SQL, dbt, Redshift, Postgres, Looker (+ LookML), Fivetran, Airflow, Salesforce

We're looking for 5+ years in analytics/data engineering, deep hands-on dbt experience, strong SQL, and a track record of turning messy datasets into a trusted single source of truth. Bonus points for retention/lifecycle modeling, Looker administration, prepping datasets for AI consumption, or Medicare/insurance experience.

We're a consumer fintech with 20M+ users who trust us to budget, save, invest, and bank in one place. Profitable for 4+ years. And as of today, our average employee tenure is 3.6 years, a number you almost never see in startup tech, and one we're quietly proud of. People stay because the work is good, the people are sharp, and we've built something worth staying for.

Now we're building net-new consumer products from zero, and we're looking for people who love to tinker and build stuff to ship them with us.

The kind of person we're looking for: • Top fraction of a percentile in craft, the kind of good that's hard to fake • Builds for fun, not just for work. The kind who ships a working prototype over the weekend and can't help themselves • Comfortable owning 0 to 1 consumer products end-to-end • Allergic to politics, theater, and bureaucracy

What you get: • Remote, anywhere with reasonable timezone overlap (and for someone truly exceptional, we'll make async work) • Real scale from day one (20M+ users, real money, real consequences) • Compensation that beats the market. We pay well and we mean it. Base, discretionary year-end bonus, meaningful 401(k) match, and meaningful equity in a profitable, growing unicorn (the kind that's actually worth something) • Platinum PPO health benefits with Blue Shield, top of the top of the line, covering your entire family • A mission worth your time: make money simple, so people spend less time managing it and keep more of it • Small senior-heavy teams, direct ownership, no layers • Forthcoming with the business metrics that matter, so you always know how the company is actually doing • The startup perks done right: catered lunches, wellness stipend, team offsites, casual dress. The stuff that compounds when you're showing up engaged for years, not months • Profitable for 4+ years, so you build with conviction, not runway anxiety

Stack: python, claude, postgres, react.js /react native

If this is you, email us at recruiting@albert.com

Edit: we are in the process of rebuilding our career site to speak to how we hire (e.g. hunt, dont post, find the best). Just an FYI

Also, we carefully review every application. If we think there may be a fit, we'll reach out within a few business days. Either way, thank you for your interest in what we're building and for taking the time to connect with us.

Cogram is an AI platform for the architecture, engineering, and construction industry. We automate project admin such as RFIs & submittals, email filing, field notes, meeting minutes, and reporting. World-leading architecture and engineering firms have adopted Cogram at scale. We're backed by YC and Initialized.

We're looking for product engineers that ship high-quality software and are good at talking to users and understanding requirements. You're comfortable across the stack and own features end-to-end. A strong sense for good UI/UX is required. Experience in architecture, 3D modeling / CAD / BIM, or building industry-vertical AI agents is a big plus.

Stack: Python (FastAPI), Postgres, Redis, React/TypeScript, React Native/Expo, Terraform/Kubernetes on AWS & Azure. Fully remote, three off-sites/year, ~38 paid days off, competitive salary + equity.

Apply: r+hnhiring[at]cogram[dot]com with GitHub/LinkedIn/portfolio and a short note, including your current agentic-coding setup. No AI-generated emails, please.

We do enterprise document ingestion — capture a document once into a canonical field registry, then project it to any schema, no re-extraction. Stack: AWS, Docker, Railway.

We've never had a dedicated reliability owner and it's starting to show. You'd be the first: SLOs and an error-budget policy that actually gets honoured, observability worth paging on, post-mortems that change the architecture, deploys nobody dreads. Target is 99.9%. Compliance is real here (GDPR, ISO 27001/42001, HIPAA), so reliability and audit work overlap.

Haven't used Railway? Fine, we'll onboard you. We ship with Claude Code day to day — if that's interesting rather than irritating, good.

Process: founder chat (bring a Sev1 you've owned), a paid day building with us on something real, team fit, references.

We’re looking to scale our engineering leadership team with technical leaders who want to raise the impact of a high-performing organization.

* Not Your Traditional "Jira-Manager": Our EMs are not classic delivery coordinators who shuffle meetings or build heavy processes. Instead, you will own people, hiring bar, technical judgment, and the health of our engineering systems.

* High-Autonomy Team: Because 80%+ of our engineering team is Senior–Staff+ level, our engineers already possess a high degree of ownership. Your focus is less on day-to-day task coordination and more on coaching independent owners, managing ambiguity, and raising team impact.

* Technically Credible Leaders: You will stay close enough to the work to challenge assumptions, review proposals, spot maintainability issues, and jump into the code to debug alongside engineers when needed.

* Organizational Advocates: Beyond your immediate team, you will act as an advocate owning the health and metrics of org-wide areas—ranging from CI/CD health and developer productivity to customer success collaboration and on-call sustainability.

* 100% Remote Async Culture: We maintain an even distribution of engineers across North America and Europe, optimizing for minimal process and maximum focus.

* Here's how we're thinking about AI at Ashby:https://www.ashbyhq.com/blog/engineering/ai-ashby-engineerin...

* Full transparency on engineering levels + comp:https://www.ashbyhq.com/blog/engineering/leveling-and-compen...

Stack: TypeScript (frontend & backend), React, GraphQL API, Node.js, Postgres, Redis. (While you won't always be shipping code, you are expected to hold a deep technical understanding of the system).

Across all roles we're looking for at least three years of relevant experience, and we're hiring senior and staff level engineers as well.

Our tech stack includes Node.js, React, PostgreSQL, AWS, Tailwind, and Python. We use both JavaScript and TypeScript heavily. Our team uses LLM-based tooling day to day, but we're fundamentally a human-centric team, and our product itself does not heavily feature AI components.

To apply please email kyle@snout.com.

My name is Marius and I am the CTO at AREO (https://goareo.com/).

AREO, founded in January 2023 by a team with 20+ years of combined experience in retail and startups, is a young startup specializing in developing innovative solutions for supermarkets and grocery retail stores.

Our cutting-edge B2B SaaS platform optimizes workflows for employees by providing real-time access to inventory, product information, and customer inquiries. We serve large supermarket chains in Germany and across the EU.

We already hired two backend developers through "HN - Who is hiring" and are now seeking a Lead Product Engineer (Ruby on Rails) / Engineering Manager (Ruby on Rails) with a minimum of 8 years of experience (preferably in startups), as we recently closed another large contract with a major retail chain and are growing quickly.

For both the Lead Product Engineer and Engineering Manager roles, professional knowledge of German is required, and you need to be based in the EU.

If you're passionate about building innovative retail products from scratch, these roles are for you.

Backend Stack: Ruby / Rails (8.x), StimulusJS / Hotwire / Turbo, AlpineJS, Postgres, Docker, DigitalOcean, OpenAPI, LLMs

We are also seeking a Robotics Lead to help us set up and run our new robotics lab in Bremen, Germany. We are building a retail robot, initially focusing on teleoperation and later on autonomous model development. You should have at least 3 years of experience with humanoid robots, VLAs, teleoperation, and other relevant robotics systems. Professional knowledge of German is required, and you must live in or be ready to move to Bremen.

Perks: Fully remote roles in Europe for the Engineering Manager and Lead Product Engineer, work where you are most productive, sizeable equity in a rapidly growing company, flat hierarchies, no-ego work environment, work in a lean but highly experienced team.

Apply here: marius[at]goareo.com and mention "HN - Who is hiring?" and the role you are applying for in the subject.

Distru is the #1 ERP in the cannabis industry. $3.5B in annual GMV flows through our platform, and most of the top cannabis brands and distributors in the US run their entire operation on us to stay compliant.

We're profitable, stable, and growing. No runway anxiety, and we're reinvesting into new product lines. We're an intrinsically motivated team that works without ego, is constantly learning, and genuinely cares about our people (5/5 on Glassdoor).

Distru is at an inflection point. We have deep market penetration in cannabis ERP, a new commerce layer (Distru Commerce, a B2B wholesale marketplace) live and growing, and a roadmap with a growing AI component. Our live AI Order Agent already lets buyers submit orders in any format from any source, killing manual data entry, the first of many bets on using AI to strip the repetitive heavy lifting out of running an ERP.

The roles: You'll own mission-critical parts of the product end to end, from planning and design through implementation, testing, and shipping. You might work on AI-native features (order/purchase intake, smart product matching, systems that learn from user feedback), Distru Commerce storefronts and ordering, manufacturing and distribution workflows, cultivation mobile tools for the floor, or compliance integrations with state systems like Metrc. These are high-ownership roles: you'll partner directly with product, design, support, and our C-suite, and you'll get customers writing you personal "thank you" emails.

Stack: React + TypeScript, Elixir/Phoenix + GraphQL, PostgreSQL, React Native, LangGraph

Canopy builds the real-time coordination layer for hospitals: communication, safety, location intelligence, and response across large, complex care environments. Every hospital is a logistics problem wrapped around a clinical one, with millions of people and events an hour across the country. When a building can sense itself in real time, the gap between an event and the right person arriving goes from minutes to seconds. People are safer, care arrives faster, and hospitals and clinics get a path to modernize on the infrastructure they already run. Sensing is the foundation.

You'd build our next-generation sensing and ML pipeline (the "physical full stack"), from sensors and embedded firmware through edge algorithms to the backend and frontend services. Physics-based modeling for sensing problems that traditional IoT products can't solve, in devices that have to survive harsh environments. We care deeply about hardware-in-the-loop platforms, simulations, and internal tools. Ideal candidates have shipped production features on both sides of the hardware/software line.

What we've deployed recently: TypeScript, WASM, Rust, C, Python, RTOS (Zephyr, FreeRTOS), embedded Linux.

If you care about the difference between 99.99% and 99.999%, and about the frontline medical staff relying on that last nine, you'll like it here.

Apply: https://job-boards.greenhouse.io/canopyworks/jobs/4317128009 AND email hn <at> (company domain) about a real-world sensor that broke your prior assumptions: what you expected, what the data actually did, and what you changed.

We're looking for a senior-level Go developer who can design and ship idiomatic code our users love to work with. We can all write Go that compiles, but don't always know what best practices for 3rd party code are (in the Go ecosystem specifically). Ideal candidates are a part of the Go community / ecosystem and know what the current best practices are. They also probably have TypeScript experience (most of our tooling is TS) and in a perfect world, Ruby/PHP ecosystem knowledge (the other languages we're currently seeking expertise in). But, if we get a Go expert who's willing to learn a bunch of TypeScript, that probably works!

We're a Dental Support Organization running 65 practices across TX/OK/CO/MO/IA/NE/TN/AZ. The unsexy industry description hides what's actually an interesting technical role: a small dev team with real ownership, pushing hard on automation and AI to make dental operations actually work well.

Stack is primarily Rails 8 + React, Electron, C# .NET (OpenDental), and Go — all on AWS.

You'd be joining a tight team where developers own problems end-to-end: from understanding why a billing workflow breaks down, to designing the fix, to shipping it. The domain is surprisingly broad — patient communication, PMS integration, payroll, clinical workflows — and there's no shortage of genuinely novel problems once you learn the business.

Good fit if you like: stable company, small team, broad latitude, and work that visibly matters to the people using it. Not a fit if you need a large eng org — but there's plenty of greenfield work as we're still actively building new features, not just maintaining legacy code.

Hi, we are a small group trying to bring the "trustworthy" feature back to tech. Curating and building a FOSS+ toolset, storefront, and eventually online service—all to support freedom, privacy, and informed consent—on device and on the net.

We've written our thoughts and research down at: https://trustworthy.technology/ and we have a few geeks starting projects at: https://codeberg.org/aol

First off, you'll notice that you've not heard about this project before. Next, the message is a bit scattered, and the "programmer art," while arguably not horrible isn't winning any awards either, haha.

That's where you come in.

You are one of the few folks who really cares about this stuff, and also a graphic/product designer, or perhaps a digital marketer, communicator or "people whisperer." (Being in the EU would be helpful as well, to work from the digital sovereignty angle, though not required.)

Some of us are unemployed, don't have any money of note, and currently donating our time. Maybe you are too, or retired/cashed-out and bored. Consider this another FOSS-like project. We hope the store/service will make money, but we're not there yet.

Interested? Let's chat at: https://trustytech.zulipchat.com/join/ipafmtlcq5iwrlmk2v7pu4...

We're looking for the second hire on our marketing team! You might wonder, why post about it on HN? If you are the kind of tech-savvy marketer that has worked on developer tools or infrastructure software before, and reads HN to keep up with the latest, this might be a fit for you. Our marketing stack utilizes Claude Code for some automation (summaries, posting, etc), but we keep the actual writing human authored - if that appeals to you, reach out!

Email me directly (the Founder & CEO) at lukas AT pganalyze.com - or fill out the form on the website.

We're building software that helps employers replace traditional group health insurance with individual plans, making healthcare less expensive and easier to navigate for everyone involved. We're doing it now because recent regulatory changes and advances in AI have made it possible. We're building at the intersection of healthcare, fintech, compliance, and AI.

Implementation is getting cheaper; engineering judgment is not.

We're looking for engineers who enjoy turning ambiguous problems into production systems, working across product and architecture, reviewing AI-generated code, building leverage through automation, and shipping quickly without creating a maintenance disaster.

Strong Python or TypeScript experience (or equivalent), good judgment, and good communication are more important to us than checking every box. US residency required, with a preference for candidates in the Eastern Time Zone or nearby.

We're looking to bring on a couple of people to help accelerate this development process.

As a data engineer you'll set up a data pipeline, work with product to identify relevant datasets, connect, persist and expose that data.

Working on the routing engine you'll extend off the shelf routing engines (Graphhopper) to take into account dynamic run-time preferences & attributes (think temporal).

Senzing builds enterprise entity-resolution SDK technology — an embeddable library that runs entirely inside customer infrastructure with zero data exfiltration. We're hiring a platform engineer to own AWS infrastructure for Placekey (our location-data subsidiary, production API at scale) and support Senzing's core ops.

This isn't a keep-the-lights-on role. We just completed an infra migration and are actively modernizing. You'd own day-to-day operations, harden the new environment, and have real input on where it goes.

Stack: EKS Fargate, Aurora PostgreSQL, S3, Lambda, Cloudflare, API gateway (Kong/AWS), Terraform, Grafana/CloudWatch/Datadog. Apps are Scala and Rust. Looking for: 5+ years platform/cloud infra, production Kubernetes (EKS ideal), managed Postgres (backup/recovery/tuning), IaC, solid networking, strong Python/Bash.

Remote anywhere in the USA. Competitive salary, full health/dental/vision, 401(k) match, flexible PTO.

To apply: email enghiring@senzing.com with your resume and a short note — tell us about a challenging production system you've owned end to end, including an incident where your monitoring missed something and what you changed afterward.

Hi HN! I'm Seema, Tech Recruiter at Ojin, and we're looking for another Product Engineer to join our small team.

We build the infrastructure that makes AI feel human — real-time AI agents with natural, lifelike conversation on a globally distributed GPU fabric. We've spent 5+ years proving this works for enterprise customers and we're now opening it up as a developer platform.

You'd own features end-to-end: interactive frontends through to Python-based agentic backends, working directly with the founders on a 15 person team. You help define the solution, design the architecture and ship it.

Stack: TypeScript, React, Node.js, Python, WebRTC, WebSockets, AWS

Looking for: 3-5 years, genuine full-stack ability, startup experience and genuine curiosity about how AI systems actually work in production.

We're not able to offer visa sponsorship or relocation support for this role - you'll need to already be based within CET ±2h and have the right to work where you live.

Founding AI engineer seat. AI adoption at Portless today is basic (decks, spreadsheets, call summaries, a bit of vibe-coded dashboards) — no real end-to-end agentic workflows yet. You'll build the AI infrastructure: shipping high-impact agentic workflows yourself, and building reusable "Lego blocks" (APIs, MCP tools, docs) so any team can build their own. Cross-functional, high-leverage role touching every team, working directly with leadership. Example first project: an agent for inbound invoice questions — understands the question, pulls the right invoice, drafts a context-aware reply for a teammate to click-send, turning an hour of work into ~30 seconds.

Requirements: Must be based in North America. 3+ years software engineering with 1-2+ years building production AI systems, 10+ real agentic/LLM workflows shipped end-to-end, platform mindset (built tools/infra for others, not just yourself), strong Python and/or TypeScript across backend and lightweight frontend, relevant sector background (e-commerce, 3PL, logistics, or comparable B2B).

Nice to have: RAG pipelines, vector DBs, multi-step tool-use/agent orchestration, evals frameworks. Full JD + Apply: https://uctalent.io/referral/Huynh_Nhu_Bao_Nhan221138/erKmmo...

Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.

Traction: - Launched Jan 2024; ~$8M committed ARR across 10+ health systems (deals ~$300K–$2M) - Live in 20+ hospitals and growing quickly - ~$37M raised (Oak HC/FT, Norwest, .406, plus customer-investors MemorialCare & Rochester Regional Health)

How we work: We’re extremely customer-obsessed: everyone visits customer sites (including engineering) and we regularly build alongside operators to solve real problems (not hypotheticals). High ownership, high candor, high velocity.

Who we're looking for: Engineers who learn quickly, reason clearly about hard problems, and want to ship high-impact product at the intersection of AI + operations + healthcare. If you're interested, email me mark@vitalize.care

Detections.ai is building the platform for teams to create, test, organize, share, and improve detections.

We’re hiring a full-stack/product engineer with hands-on detection experience—writing or tuning detections, building SOC tooling, or integrating SIEM/EDR platforms.

You’ll own product features end to end across React interfaces, backend services, APIs, data models, search, integrations, and asynchronous workflows.

LLMs are a core product capability, not a bolt-on chatbot. Our assistant orchestrates domain tools and agents to analyze threat intelligence, search detection libraries, identify coverage gaps, create and translate detections, and ground recommendations in connected SIEM telemetry. We care about accuracy, evals, observability, hostile-input safety, and practitioner UX.

AusRehab is a workplace rehabilitation provider in Australia — we help injured workers in the NSW workers' compensation scheme return to work. We're replacing a stack of off-the-shelf systems with in-house, AI-driven ones, so our consultants can do their work better: fewer errors, statutory deadlines met, clearer communication with workers and insurers, and the audit and regulatory requirements handled properly rather than remembered at the last minute.

For this we're assembling a small team of 3-4 full-stack developers who will work directly with our rehab consultants to design systems that actually fit the task. You'd own solutions end to end, with real autonomy and no ops team to hand your infrastructure to. You'd also talk to the people using what you build.

Stack: Python, TypeScript, React, React Native, PostgreSQL, AWS (Lambda/S3/SQS/EC2), GitHub Actions.

Prior experience with ML, NLP, and agentic AI systems is highly desirable, but not essential.

No workers' comp knowledge needed, but we do ask for a curious mind to learn from an unfamiliar domain.

Chainguard is the trusted source for open source. We build hardened, minimal, continuously-updated images, libraries, and packages that eliminate vulnerabilities before they ship — used by teams at Anduril, Canva, OpenAI, Snap, and Snowflake, among others.

We're hiring a PM to own the malware and greyware scanning engine inside Chainguard Repository — the system that analyzes source code, build behavior, and maintainer activity across the open source packages flowing through our platform to catch compromised or malicious artifacts before they reach a customer's environment. You'd own the roadmap for detection coverage, scanner accuracy (precision/recall trade-offs are the daily grind), and how findings get surfaced to security teams and translated into policy enforcement. Close partnership with our detection engineering and threat research teams, and with customers who are increasingly asking "how do you know this package is safe?"

Good fit if you've done PM work on a detection, fraud, spam, or security scanning system before, are comfortable being hands-on with data and false-positive/false-negative trade-offs, and want to work on a problem that's getting more urgent as AI agents pull in more open source dependencies automatically.

JD to be posted imminently but email me if interested and I'll route appropriately: patrick@chainguard.dev

Everyone building with AI is crowded into the digital world: dev tools, copilots, agents for software people. Meanwhile the largest asset class on earth, the built world, runs on records scattered across 20,000+ US jurisdictions, and most of those have no online portal at all. The only way in is a relationship and a public-records request, and you cannot download a relationship. We turned that into the intelligence layer for the built world: permits, contractors, parcels, government decisions. Customers pay for it today.

Unitary Foundation is a 501(c)(3) non-profit research group building a quantum technology ecosystem that benefits the most people. We build open-source infrastructure for quantum computing — current projects include Mitiq, UCC, and Clifft — and run community programs like microgrants and unitaryHACK.

We're hiring an MTS to help define and build our open-source compilation and simulation stack: compilation, simulation, error mitigation, resource estimation, benchmarking, and early fault-tolerant workflows. You'll join a small technical team doing research through sponsored collaborations with national labs, universities, and industry partners. The role is about technical ownership — forming a technical point of view, proposing roadmaps, and building tools that become useful shared infrastructure. There's also room to experiment thoughtfully with AI-assisted research workflows.

We're looking for a track record of building software other people use (ideally open source), a strong background in quantum computing (fault tolerance, error correction, compilation, simulation), and strong Python; C++/Rust is a plus. A PhD is one possible background for this role, but not required.

Instinct Science is the AI leader in veterinary medicine. We build the platform that powers animal hospitals — a cloud-native EMR with real-time clinical decision support and applied AI that helps veterinary teams practice at their best. Thousands of users across the globe rely on what we ship every day.

We're at an inflection point: proven product-market fit, scaling fast, and greenfield work ahead that will serve tens of thousands of users. Engineers here own problems end-to-end — from talking to veterinarians about their biggest frustrations, to shipping production code, to iterating on real feedback. You're measured by customer impact, not story points.

WHAT YOU'LL DO: - Drive product direction alongside customers and PMs — not just implement specs - Design scalable, elegant solutions in Elixir and React - Ship meaningful updates weekly, gather feedback, and iterate - Mentor junior engineers and define patterns that scale with the team

WHAT WE'RE LOOKING FOR: Must-haves: - 5+ years building modern SaaS applications, full-stack - Ability to break complex problems into efficient, actionable work - Team-first attitude; strong communication in a remote environment - Empathy for customers — you care about what ships and who uses it

Nice-to-haves: - Elixir or Erlang (we love functional programming) - TypeScript and React - AWS (build, deploy, troubleshoot) - Relational database design and query tuning

STACK: Elixir, React, TypeScript, PostgreSQL, AWS

We deliver multi-gigawatt power to AI data centers, and this is the founding hire on the team that forecasts load and market prices. You own the whole spine: ISO/RTO market feeds, weather and plant telemetry through feature store, serving, drift detection and the model gateway.

Not a scale problem — the data is rich, not petabyte. Feeds land late and get revised after the fact without ever throwing an error, so the failure mode is a price series quietly wrong for three weeks behind a forecast that looks fine. The work is trust infrastructure: lineage, freshness SLAs, point-in-time correctness, eval gates that can block a model.

Python, SQL, Airflow, containers, IaC. 5+ years on production data and ML platforms; energy background welcome, not required.

We’re hiring an AI-native engineer to work with Earl on a live project inside a Premier League football club. This is not an AI strategy role, and it’s not a chatbot demo job. You’ll work directly with people inside the club's commercial team, find valuable problems, and build production AI systems that are actually used.

We’re looking for someone who can move from vague problem → technical design → working product quickly.

You do not need football experience.

You do need strong product judgement, the ability to work directly with non-technical users, and evidence that you’ve actually shipped things.

We’re particularly interested in people who build with AI as their default way of working, rather than conventional engineers who have recently added an LLM API to their CV.

To apply, send me:

- A short intro - 2-3 things you’ve built What you personally did - How you currently use AI to build software - Location and availability

Strong candidates will do a paid practical working session.

We're looking for someone who has the experience to move fast on new stuff and knows how and when to pick their battles on old stuff. You'd be one of four iOS engineers at a company that's big enough to survive an economic downturn, but not so big you can't make immediate, direct impact that'll be seen and appreciated by the whole company. (We've also spent the last decade working really hard to make sure our tools, processes, and culture respect everyone's work/life balance. I'm the CTO and I don't text people on my team, and they don't text me, and that's true throughout.)

It's a native iOS app written in a mixture of Objective-C and Swift, leaning on Swift for new features. (But that said: if you chafe at the idea of maintaining or fixing bugs in battle-tested Objective-C that's paying our salaries, please look elsewhere!)

Connie Health is a fast-growing Medicare brokerage on a mission to empower older Americans to make confident, worry-free Medicare plan decisions. We offer a tech-enabled Medicare navigation platform that combines AI-driven technology with local Medicare experts to help people select optimal healthcare plans and navigate their benefits. Backed by leading investors such as Khosla Ventures, we are building technology to transform the trillion dollar Medicare insurance industry, impacting the lives of 67 million people in the US.

We are looking for a Senior Analytics Engineer to own our data transformation layer end-to-end. You will build the clean, well-modeled, documented datasets that the entire company relies on, spanning board-level book-of-business reporting (policy count, retention, effectuation, commissions), stakeholder self-service through Looker, and AI-driven exploration through tools like Claude. This is a high-leverage senior IC role: the quality of our analytics, forecasts, and operating decisions all depend on the foundation you build. You'll partner directly with Engineering, Finance, and Operations to fix data quality at the source, not downstream.

Tech stack: SQL, dbt, Redshift, Postgres, Looker (+ LookML), Fivetran, Airflow, Salesforce

We're looking for 5+ years in analytics/data engineering, deep hands-on dbt experience, strong SQL, and a track record of turning messy datasets into a trusted single source of truth. Bonus points for retention/lifecycle modeling, Looker administration, prepping datasets for AI consumption, or Medicare/insurance experience.

Looking for top-notch senior+ engineers. Must be a great engineer who understands their craft in-depth. Prefer people who strive to understand the business domain and don't merely follow verbatim Jira stories. Some roles require capital markets experience (details in job posts below). Long term engagements. 100% remote, but only for people based out of Poland or Romania.

Details at https://vistulo.com/roles/hn0607/ . Apply via link in job post. If you know someone who could be great for the role, referrals are welcome (see details in ad).

Acme is building a product. We are an early-stage company at the ground floor — no code yet, no customers yet, just a clear vision and a bias for action. We are looking for a founding engineer who wants to build something from nothing: architect the system, write the first line of code, ship the first version, and grow alongside the company.

What You'll Do: - Build the product end-to-end — from database schema and API design to frontend UI and deployment infrastructure - Make architectural decisions — choose the tech stack, set up CI/CD, monitoring, and dev environments - Ship iteratively — get working software in front of users fast, then improve based on real feedback - Set engineering standards — establish coding conventions, code review practices, and a culture of quality - Influence product direction — work directly with the CEO on what to build, what to cut, and how to prioritize - Own the infrastructure — provision cloud resources, manage deployments, and keep the app running in production

Who You Are: - 3–8 years of software engineering experience, preferably in early-stage startups or with significant side-project shipping - Full-stack capable — comfortable across frontend, backend, databases, and infrastructure - Ship-focused — 80% today beats 100% next month. Pragmatic tradeoffs between speed and quality - Independent — thrive without a playbook. Figure things out, make decisions, communicate clearly - High ownership, low ego — care about the mission and the team, not about who gets credit - Product-sensible — good judgment about what users need and what can wait

Compensation: Competitive salary + meaningful equity (2–5% range)

How to Apply: Send a note to the CEO with what excites you about early-stage building, a link to something you have built (GitHub, portfolio, side project), and why Acme specifically. No formal resume required.

We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.

We're looking for software engineers who value software design, system architecture, and collaboration. You should be strong in most of these areas: web application security, relational database design (PostgreSQL query plans, indexes, and constraints, not whatever the ORM emits), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect race conditions.

A note on how we work: we think deeply about the systems we build, and we believe understanding comes from doing the work yourself, not from handing it to a model. If you ship code you don't understand, we're genuinely not a fit, and that's fine. If that paragraph made you nod, we want to hear from you.

We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll work with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

We're looking for a senior engineer who is pushing the boundaries of AI-assisted software development.

Everyone says they use AI. We're looking for someone who has gone much further—someone who is constantly experimenting with new workflows, building agents, automating entire pieces of development, and rethinking what one engineer can accomplish.

Our engineering team believes AI is fundamentally changing what great engineering looks like. We want people who are helping define that future—not waiting for someone else to.

Our stack includes Ruby on Rails, React, PostgreSQL, AWS, Sidekiq, and Stripe, but we're far more interested in how you build than the specific technologies you've used.

If you're excited by questions like:

How can AI own an entire feature from design to deployment? What engineering work still requires humans, and what should be automated? How do we move dramatically faster while maintaining an exceptionally high bar for quality? What does an engineering organization look like when every engineer has AI teammates?

...you'll probably enjoy working with us.

If this resonates, we'd love to hear from you.

Prolific is not just another player in the AI space – we are the architects of the human data infrastructure that's reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditized, it's the quality and diversity of human-generated data that truly differentiates products and models.

We’re looking for impact-focused Software Generalists to join our specialized team focused on serving frontier model creators and enterprise AI application developers. As a full-stack engineer, you will work across Prolific’s domains to solve customer and product problems.

This is an exciting opportunity to work directly with frontier AI companies, making critical technical decisions that balance scrappy startup execution with scalable, reliable engineering, as Prolific revolutionizes research for the AI community. You'll will have regular in person collaboration with customers and our US team, as well as collaborate closely with our UK-based tech teams.

Unfortunately we don't sponsor US visas at this time.

Hi! We're Ontix. Among other things, we're building the business layer to connect siloed datasets and query them with natural language, offering insights to SMBs they couldn't get before. We're fully funded by our sibling company, and are looking for freelancers and small business owners in the US to join our network. Our business model relies on a close-knit and highly-skilled group of outside partners to work on projects depending on the capabilities required. We're looking for experience in the following role:

+ Product management: We're looking for a tech-focused project, product, team or program manager familiar with website and software development, AI and QA. You'd be working with a team of two to five developers, designers and other project managers, keeping everyone on-task and informing management of progress. You'd work closely with account and technical leads to gather requirements from and suggest recommendations for the customer. Asana power users will move to the front of the line.

We're looking to grow quickly as our client base expands. If you're interested in this role, or would like more information in general about us, please visit https://ontix.io or email l33t@ontix.io with a few sentences describing your experience, interest, and where you're located.

United States citizens and legal residents only please. Replies accepted through July 31, 2026.

StatusPal helps engineering and IT teams detect, fix, and communicate incidents — monitoring, incident response, and status pages in one platform. We're small, profitable, and bootstrapped (no VC, no runway clock), with real revenue and customers. What we haven't built yet is a growth engine — that's this role.

We're hiring our first commercial hire to own go-to-market end to end: both marketing/demand (content, SEO, partnerships, paid) and sales (outbound, demos, closing). You'd wake up thinking about how we sell more, lean on AI to punch above your weight, and bring in freelancers or reps when the numbers justify it — running the whole function so it compounds without the founder in the day-to-day. Strong fit if you've done a hands-on 0→few-million at an early-stage B2B SaaS and want real ownership and upside over a big-company base.

Not a fit if you want a finished playbook, warm leads handed to you, or to be purely a marketer or purely a closer — this role owns the whole path.

I'm the founder and will reply to everyone. Full details + apply: https://statuspal.notion.site/Founding-GTM-Lead-39009d5544a7...

We're building a peer-to-peer exchange where fans buy and sell positions in individual athletes, like a stock. Real money, central limit order book, mechanical settlement against a published rules-based rating computed from official on-field stats. There is no house. Fans trade against each other like a prediction market.

We are far along on everything except the build. Rating methodology is designed, legal structure is scoped with counsel, payments and data vendors are selected, and we ran a beta this past NFL season that drew ~1,000 organic users and 21,000 trades in four weeks. The founding team was part of Founders Inc, and we are about to open our seed round.

We are hiring the engineer who owns the entire technical build, with no inherited architecture and nobody between them and the problem:

Matching engine and order book Rating and settlement engine, deterministic, computed from official stats Ledger, custody, and the real-time data pipeline Every architecture decision, including one we have deliberately left open: on-chain vs off-chain custody and settlement at v1

Looking for someone who has built correctness-critical, concurrent systems. Trading, exchanges, payments, or comparable. Language is open. We care about systems depth, not a specific stack. Two non-technical founders, so you would own the technical domain completely and be the technical voice with investors and eventually regulators. Email me leon@fansharesapp.com if interested, thanks

AI usage today is basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows yet. This is a founding seat to build that: shipping high-impact agentic workflows yourself, plus reusable building blocks (APIs, MCP tools, docs) so any team can build their own.

Example first project: an agent for inbound invoice questions — reads the question, pulls the right invoice, drafts a context-aware reply — turning an hour of manual work into ~30 seconds.

Need: 3+ yrs SWE with 1-2+ yrs shipping production AI systems, 10+ real agentic/LLM workflows built end-to-end, a genuine platform mindset (built tools/infra for others, not just yourself), strong Python and/or TypeScript, and relevant sector background (e-commerce, 3PL, logistics, or similar B2B).

Nice to have: RAG pipelines, vector DBs, multi-step agent orchestration, eval frameworks.

Full JD + Apply: https://uctalent.io/referral/Huynh_Nhu_Bao_Nhan221138/DNwhgw...

We're a company doing real operational work in e-commerce/3PL logistics. AI usage internally is still basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows in production yet. That's what this role is for. You'd be the first dedicated AI engineer here. Two things at once: ship agentic workflows that replace real manual work, and build the underlying platform (APIs, MCP tools, docs) so other teams can build their own instead of asking you for everything forever. First project: an agent that reads an inbound invoice question, pulls the correct (often complex) invoice, and drafts a context-aware reply a teammate can review and send. Currently ~1 hour of manual work, target is ~30 seconds. What we need:

3+ years SWE, 1-2+ of which building production AI systems (not prototypes) 10+ agentic/LLM workflows shipped end-to-end — not toy demos Evidence you've built infra/tools for other people to use, not just yourself Strong Python and/or TypeScript Some background in e-commerce, 3PL, logistics, or comparable B2B ops

Nice to have: RAG, vector DBs, multi-step orchestration, eval frameworks, heavy Cursor/Claude Code/Copilot usage. Fully remote, direct access to leadership, real scope to define how AI gets built here rather than inheriting someone else's stack.

I need an experienced Unity graphics specialist to reboot a beloved and unique simulation game IP as part of a small dedicated team. You are comfortable writing terrain, foliage, atmospherics, volumetrics, particle system from scratch, along with more typical URP/SRP dark arts + fell workings. You are OK with an opinionated codebase that largely sidesteps standard Unity stuff.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Ashby is the all-in-one recruiting platform powering hiring at the world's most innovative companies. If you cmd+f "Ashby" you'll see that we're powering many of the job postings in this thread!

We’re looking to scale our engineering leadership team with technical leaders who want to raise the impact of a high-performing organization.

* Not Your Traditional "Jira-Manager": Our EMs are not classic delivery coordinators who shuffle meetings or build heavy processes. Instead, you will own people, hiring bar, technical judgment, and the health of our engineering systems.

* High-Autonomy Team: Because 80%+ of our engineering team is Senior–Staff+ level, our engineers already possess a high degree of ownership. Your focus is less on day-to-day task coordination and more on coaching independent owners, managing ambiguity, and raising team impact.

* Technically Credible Leaders: You will stay close enough to the work to challenge assumptions, review proposals, spot maintainability issues, and jump into the code to debug alongside engineers when needed.

* Organizational Advocates: Beyond your immediate team, you will act as an advocate owning the health and metrics of org-wide areas—ranging from CI/CD health and developer productivity to customer success collaboration and on-call sustainability.

* 100% Remote Async Culture: We maintain an even distribution of engineers across North America and Europe, optimizing for minimal process and maximum focus. * Here's how we're thinking about AI at Ashby:https://www.ashbyhq.com/blog/engineering/ai-ashby-engineerin...

* Full transparency on engineering levels + comp:https://www.ashbyhq.com/blog/engineering/leveling-and-compen...

Stack: TypeScript (frontend & backend), React, GraphQL API, Node.js, Postgres, Redis. (While you won't always be shipping code, you are expected to hold a deep technical understanding of the system).

We're working at the forefront distributed systems engineering, interface design, and agentic computing to bring about the infrastructure platform we've always wanted. So far we've built out a platform loved by 3M+ users and we're just getting started.

Fair warning! The problems are complex: racking and stacking servers, home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.

I've been obsessed with CRDTs since I first saw them at Strange Loop years ago, and I still can't quite believe I now get to work on them for a living — in some of the most challenging environments there are: disconnected, degraded, contested, out where the cloud isn't. If that's your kind of problem, come build with us.

Ditto is the edge-native data platform that keeps distributed systems in sync when the network doesn't cooperate — an offline-first, CRDT-based layer syncing any device (phone, vehicle, sensor, server) over Bluetooth LE, P2P Wi-Fi, LAN, and tactical radio, with or without connectivity. Same core, commercial to defense; operationally deployed and network-agnostic. The problems are the fun kind: conflict-free replication with no server and no synchronized clock, multi-transport routing that never drops the connection, moving a coherent picture over links as thin as an HF radio shot, and human-in-the-loop robotics/autonomy where a detection may have to be physically carried by a moving node. Concept to field in days, not months.

Most roles are open to anyone authorized to work in the U.S.; Public Sector and forward-deployed roles require U.S. person status. Remote in the U.S. (hubs: Atlanta, Austin, SF, Seattle) unless noted.

We’re hiring for:

Senior Systems Engineer — Capture & Materializations Design and build high-performance connectors that move data in and out of Estuary in real time. Work across APIs, databases, and streaming systems to ensure correctness, reliability, and scalability. This role is deeply systems-oriented, with a focus on data plane execution. Go and Rust are core to our stack.

Senior Front-End / Full stack Engineer - Build highly interactive observability and data-flow experiences for the Estuary platform. Design and develop real-time visualizations of distributed data pipelines, metrics, and system health using React and TypeScript. We’re looking for engineers with deep front-end expertise, strong performance instincts, and experience building complex data visualization or developer-focused products.

Product Manager - Own product areas end-to-end, working closely with engineering and design to shape the roadmap and deliver a great developer experience. Engage with users, translate real-world use cases into product decisions, and help define how modern data infrastructure should feel to build with.

Technical Product Marketing Manager - Founding product marketing hire working closely with Estuary’s Head of Marketing and Developer Relations team. Help shape how we position and communicate the platform to technical audiences through product launches, messaging, technical content, demos, customer stories, and developer-facing campaigns.

What we’re looking for: Engineers who care about building reliable, maintainable systems and enjoy working with complex APIs and data flows. We value curiosity, clear communication, and a willingness to learn.

Bonus points for experience with CDC tools, open source contributions, or fast-paced startups.

To apply: Email your resume to careers@estuary.dev

We build AI agents that run real operations. Humans talk to our agents to run commercial real estate: leases, contractors, invoicing, accounting. We're live in production across several European jurisdictions, with real customers and real money.

We need a Forward Deployed Engineer to own a client-facing use case end to end: a strong backend engineer who is also the face of the team to the customer.

The job:

- Talk to clients directly and often. Pull requirements out of messy conversations, explain tradeoffs, own the relationship

- Turn jurisdiction-specific lease rules, tax and accounting mappings, client-specific workflows into tools our agents call

- Ship to production in your first month, then keep it alive

What we need, in this order:

1. Self-driven, real ownership. You'll have a lot of freedom and support, but the use case is yours end to end - nobody will be feeding you tickets.

2. Excellent English and real customer-facing experience. You'll be on client calls every week.

3. Serious backend experience. You've shipped and operated production systems, and can work as the only engineer in the room. We use AI tools heavily, but we don't vibe code: your engineering judgment and review are what make the code shippable, and you own what you merge.

4. LLM agents in production, or you ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call.

Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain/LangGraph, operator or consulting background.

We're a small senior team across Europe and South America. For this role we need you in Europe.

Competitive comp - we have no salary bands, for the right person we'll stretch.

Apply: mercedes@kinxshn.com, subject "HN - Forward Deployed Engineer", salary expectation and CV attached - skip the skills inventory: tell us about something hard you shipped and a customer you made happy.

Quantum Rise is an AI-forward consulting startup serving the mid-market in the US. We see companies in multiple industries struggling to understand how to leverage artificial intelligence in their day-to-day operations, trying to understand what their existing workforce now needs to know, or trying to understand whether they're about to be disrupted and need to change how their existing processes work. Many have business problems which "traditional" machine learning could help with even prior to the current GenAI hype cycle, but for whatever reason hadn't prioritized doing until now. Many have employees looking to incorporate agentic AI safely and effectively across different business areas. We try and help getting a handle around these issues and designing outcome-driven solutions.

Agentic AI Solutions Manager: You'll work directly with clients to benchmark, train and deploy agentic systems for industry-specific problems. We're looking for someone deeply embedded in agentic engineering practice across vendors and platforms. Companies are looking for ways to leverage agentic systems to upskill their practitioners and need help navigating a new, powerful scary world.

AI Solutions Engineer: You're someone who has experience across the entire spectrum of applied automation, machine learning and agentic engineering.

We think of these two roles as complementary -- agentic AI solutioners help clients understand the forefront, whereas pure AI solutioners help them pick the right solution not the one they saw in the news.

Both are front-facing development roles for someone who loves both tech and tackling real business problems. We love people with prior experience in multiple industries.

To apply, send me an email at julian.berman at quantumrise.com, mentioning HN and including your CV.

We're building the first Identity Acceptance Network, the "Visa for ID." Humanity is editing genes, starting space tourism, and verging on artificial general intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards.

Role - Senior Product Engineer (#5 on the team; ~20% of engineering capacity). High ownership, product-minded, backend and systems leaning. - This is not a ticket-churning role. You should want to understand the competitive landscape, listen in on customer calls, bring engineering insight to product discussions, and own features end-to-end. - You should be a Barrel: someone who can take on ambiguous work, pull together the right context, make tradeoffs explicit, and drive without needing to be told every next step. Revenue is surging, we need judgement to help shape the product. - Strong backend/platform experience; generalist enough to move up/down the stack when the product needs it. - You care deeply about user privacy and data security. We work on identity. Sloppiness here is not an option.

Stack & ways of working - .NET (C#) backend, React + TypeScript frontend, Azure Container Apps, Azure SQL/Storage, Bicep IaC, GitHub CI/CD. - Remote-first; North America (CT +/- 2) or Europe (CET +/- 1). Strong async work habits; 4 hrs/week of scheduled meetings on average; pairing/huddles when useful. - We use AI aggressively and prudently. You'll have a large token budget, but we expect strong judgment around the risks.

Comp & apply

- Salary is set by our compensation philosophy, with meaningful equity. We discuss compensation early so neither side wastes time.

- Apply: https://www.trinsic.id/careers/senior-product-engineer?utm_s...

If you're in a workable timezone and excited about identity infrastructure, I'd love to talk.

JP, CTO @ Trinsic

Im the hiring manager - some of the product highlights under the team's scope: - Grafana Assistant: the actually useful AI assistant that helps you do everything in Grafana; it works everywhere - even in OSS! - Investigations: background agents for investigating issues - Grafana Cloud CLI (GCX): CLI covering the entire surface of Grafana Cloud/OSS APIs; plays great with Claude Code/Codex/Cursor and the Assistant - AI Observability: helps you build useful agents and then lets you monitor, eval and improve how they behave - O11y Bench: compare agents' performance across a range of observability/SRE tasks

Our pace of development and innovation is RAPID - the AI Observability product went from being the winning hackathon project to public preview in 6 weeks. We are at the cutting edge here - we are experimenting with autonomous (but safe) SREs, an agentic platform, improving agentic dev experience with o11y insights, fine-tuned LLMs for specific tasks, and more.

We are looking for highly ambitious engineers who have a great sense of ownership, are all-in on agentic development, and have previously built and operated systems at scale. We are all full-stack and love initiative- we would love to talk with you _especially_ if you built something out in the open!

We are automating it. The challenge isn't generating text. The challenge is building systems that can be wrong almost never.

We're looking for:

- Forward Deployed Engineers who enjoy sitting with customers, figuring out what's actually broken, and building solutions faster than a roadmap ever could.

- Applied AI Engineers who obsess over retrieval, evaluation, orchestration, reliability, and all the ways AI systems fail in production.

- Account Executives

Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model.

We've been building since 2020, started in campaign security and data science, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are funded by our customers.

Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.

Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is an exciting opportunity for those who are interested in building systems and agents to solve hard and often adversarial problems.

We’re growing our team, and seeking a multifaceted engineer (2+ years experience). We’re looking for engineers with web scraping, data pipelines, or security tooling experience. Experience with Python/Django, Typescript, React, and LLM APIs is a plus. Must be authorized to work in the US.

Email steven@kanary.com with something you've built and why it was hard. Also be sure to include the keyword I’ve put in my HN profile.

We compress LLM KV cache. Measured: 8× at 3-bit with 0.43% quality delta (GPU-validated); 22× live end-to-end on a 5-tenant workload, GPU-verified this week (quantization × prefix dedup, decomposition always stated); 16.89× tenant density on a single V100-32GB. Validated across Mistral/Qwen/Llama with zero re-tuning. 90+ patents pending; design-partner pipeline; seed round in motion.

The gap: our throughput path is a reference implementation. First job is the fused Triton/CUDA dequant+attention kernel — turning a validated 22× memory result into production speed. Then you own the serving stack.

Process: call → NDA → paid 1–2 week trial on the real kernel → decide together. We report negative results straight; you should want to work somewhere that does.

We secure the SaaS apps companies actually run on: M365, Salesforce, and hundreds more. You’d be on the Threat product team working full-stack. That means browser extension code (content/background scripts, manifest v3, message passing), backend services chewing through millions of events, and the data pipelines feeding our detection engine. One day you’re in TypeScript debugging why a content script won’t capture form submissions on some vendor’s weird SPA. The next you’re in Python fixing a Kafka consumer that’s falling behind. Sometimes you’re in Rust optimizing a hot path in the telemetry collector.

Big current focus is shadow AI, i.e. catching when employees paste sensitive data into ChatGPT, Claude, or whatever LLM showed up this week. You’d build the systems that detect it.

Looking for ~8+ yrs experience, real browser knowledge (DOM, event loop, SPA routing, CORS, not just “I used React”), prior browser extension work, strong TypeScript, comfortable in Python, willing to write Rust, plus data-at-scale chops (event streaming, Postgres, Elasticsearch, Kafka). Bonus: AI security (prompt injection, exfiltration), detection engineering/SIEM, or security tooling.

Tower is a Python-native serverless data platform. Data teams write plain Python, and we handle packaging, dependency resolution, scheduling, and execution across a serverless runtime built on Apache Iceberg. There's no clusters to manage, no YAML to write, no pipelines to rewrite to fit someone else's engine. If you've ever wanted your local Python script to just run in production at scale without a Databricks detour, that's the product.

We're a small, senior team split between London and Berlin. We've built a lot of tech: Custom run dispatch service, multi-region routing, storage based on Apache Iceberg, and the runtime itself, to name a few. This is deep systems work--things like scheduling, distributed execution, and performance. We're not gluing SaaS together.

Stack: Go and Rust for the platform, Python everywhere it matters, Kubernetes (EKS + Karpenter) on AWS, RDS Postgres, ElastiCache Redis, S3/Iceberg, WorkOS for auth.

Looking for:

* strong distributed-systems fundamentals

* comfort owning a system end to end

* taste for correctness under load

Bonus: data-platform, query-engine, or Iceberg experience; async Rust; Kubernetes internals.

Tech Mahindra’s Cloud Advisory & Consulting division is hiring experienced leaders to help drive delivery excellence and financial operations for our global cloud consulting business. We are currently looking for the below roles.

Senior Delivery Manager: Lead large-scale cloud transformation, modernization, platform engineering, and managed services engagements across AWS, Azure, and GCP. The ideal candidate will have a strong background in delivery leadership, stakeholder management, program governance, financial accountability, and building high-performing teams.

Finance Manager: Partner with business leaders to manage financial planning, budgeting, forecasting, revenue tracking, margin management, and operational reporting. Experience supporting consulting, technology, or professional services organizations is highly desirable.

Orbit is an AI-first logistics operating system — order intake, route planning, carrier management, driver app, tracking, documents — replacing the Excel-and-phone stack that most of transport logistics still runs on. We're bootstrapped, profitable, and growing in a market full of VC-funded competitors. Our customers stay because the product works.

The role: we call it Product Engineer because you own a piece of the product from idea to production — deciding the solution, building it, shipping it, iterating on feedback. Not ticket-driven work. Small, strong team.

How we build: spec-driven agentic development, not vibe coding. You orchestrate agents against structured specs and persistent project context, verify output, and help build the harness itself (skills, context layers, workflows, evals). We think the engineering bottleneck has moved from typing speed to judgment — knowing what good software looks like and directing agents to produce it. If that matches how you already work, you'll feel at home.

Stack: TypeScript everywhere, zod, tRPC, Node.js, AWS (Lambda, DynamoDB/ElectroDB, SST), React/Remix, React Native/Expo. AI layer via Bedrock. You don't need to know every line of it.

Culture: all-remote (EU), async-first, low-meeting. Writing is the most important skill here. Profit sharing via our "Own Orbit" program, quarterly meetups in Hamburg, team offsites ("SpaceWalks") wherever two or more Orbiters want to meet — Orbit covers the stay. Good English required; German is a plus (customers and product are German-speaking).

No cover letter. Show us something you built — a side project, an agent workflow, a repo, an MCP server — and tell us how you work with agents.

Apply: https://join.com/companies/orbit/16414503

We're hiring a senior frontend engineer to own key parts of our frontend platform - including our shared component library strategy - across a legacy React codebase and a modern Next.js (App Router) app. This is real-complexity work, not just greenfield: modernizing older code, publishing reusable component packages in a monorepo, and building RTL/LTR (Arabic + English) interfaces with next-intl. Stack: Next.js, TypeScript, Tailwind v3/v4, Radix UI, Open edX Paragon, Zustand/Jotai, TanStack Query, Vercel AI SDK + OpenAI APIs, Jest/Testing Library. Looking for: 5+ yrs frontend experience, strong async communication, proven ability to drive work to completion independently in a distributed team. Open edX/Paragon experience is a strong plus. Flexible hours, competitive pay, and you'll work alongside engineers from the global Open edX community.

Odin is the workforce visibility and compliance platform for critical infrastructure. We protect the world's largest construction projects, data centers, and critical assets, from groundbreak to post-turnover, unifying every layer of site security into a single command center: physical access control, workforce compliance, video monitoring, and drone surveillance. We're already on 500+ active projects with 100K+ workers on the platform, securing over $100B in construction value.

Our stack is TypeScript end to end, Node and GraphQL on the backend, React on web, React Native on mobile, Postgres and Kubernetes on GCP. We also integrate deeply with field hardware such as badge readers, kiosks, turnstiles, and cameras.

Lead Platform Engineer: end-to-end owner of the platform and hardware fleet everything runs on. Product teams are your customers. You own infra-as-code, CI/deploys/DX, monitoring, hardware fleet ops, and incident escalation.

Lead Software Engineer: technical owner of an autonomous 2-3 person product team, taking scoped projects from design through release. Not a people-management role.

Both: operational maturity, a habit of mentoring, and AI used to accelerate without outsourcing judgment. Jobsite-adjacent experience (construction tech, access control, IoT/hardware) is a bonus.

Namecoach has spent 10 years building the largest verified pronunciation dataset of its kind: ~2M self-recorded name pronunciations, plus a large corpus of human-verified phonetic spellings.

We're now building Euphonia (https://euphonia.namecoach.ai/), a provider-neutral middleware layer that makes any TTS engine pronounce names, acronyms, and other out-of-vocabulary terms correctly. The new wave of TTS (models from OpenAI, ElevenLabs, etc) sounds great but gives you almost no phoneme-level control, so it gets lots of names and words wrong and you can't easily fix it. We sit in front of these engines and fix it.

We want real depth in speech and phonetics: grapheme-to-phoneme, IPA, ASR/TTS internals, and the ability to build and evaluate models around them (the recognition and G2P side especially). You should be comfortable shipping with agentic dev tools like Claude Code and Cursor. This is a 0 to 1 founding voice AI engineering role with a genuine path to Chief AI Officer for the right person.

Part-time to start (flexible hours, ~2hr/day overlap with US Pacific), with a paid take-home and a paid trial month before anything longer term. Potential conversion to full-time role. Series A closed, bridge to B in motion.

Full JD: https://wellfound.com/l/2ChdJ2

What we do:

We're a Series A, ~50 person company building the operating system for hospital labor and capacity. Hospitals today manually forecast patient volumes and staff reactively—losing efficiency, increasing costs, and compromising patient care. Vitalize automates demand prediction (leveraging ADT data, historical patterns, and acuity scores to forecast patient census) and real-time staffing optimization.

Traction: $10M ARR < 2 years. Across 30+ hospitals

Who we're looking for: Engineers who learn quickly, reason clearly about hard problems, and thrive in a high-impact environment. If you're interested, email ryan@vitalize.care

Stack: Typescript + Postgres + Effect. Large focus on being able to learn quickly and solve difficult problems

Need: 2+ yrs directly managing ~10-person eng teams, distributed/async experience, strong enough technically to run code reviews and push back on estimates (not coding day-to-day), track record raising delivery throughput at a high-growth company.

Nice to have: big-company process background (Google/Meta/Salesforce-style) mixed with startup speed, and logistics/supply chain/e-commerce domain exposure.

Must overlap ~6 hrs with US Eastern (9am-4pm ET).

Hey HN, we’re ProxyBase. We’re building an API-first, fully headless SOCKS5 proxy network designed specifically for autonomous AI agents, LLM tool-calling, and large-scale web scraping.

Most traditional proxy networks operate in a bit of a gray area—they buy bandwidth harvested from sneaky, hidden SDK bundles embedded inside free apps. We're doing things differently:

100% Ethical Sourcing: We pay our node operators directly. People run our open-source CLI client to share their bandwidth and earn microcredits in real-time. It’s fully transparent, consent-driven, and compensated.

Built for Swarms, Not Dashboards: AI agents and automated workflows can provision, utilize, dynamically route (via metadata in the SOCKS5 auth string), and settle proxy fees entirely programmatically using US based stable coins without ever touching a manual web dashboard.

Our Tech Stack:

Backend: Rust (Actix-web, SQLite/DashMap, WebSockets, Yamux stream multiplexing) Frontend / Desktop: React, TypeScript, Tauri (our client-side bridge app)

What we're looking for:

Backend Engineer (Rust): Help us scale our high-concurrency SOCKS5-to-WebSocket relay gateway and real-time ledger settlement engines. Full-Stack Developer (TypeScript / Tauri / Rust): Own our local proxy bridging software, client-side developer portal, and integration libraries. If you like systems-level programming (TCP/UDP, tunnel multiplexing, concurrent state) and want to work on clean, developer-first infrastructure, we'd love to chat.

Drop us a line at

jobs@proxybase.xyz with a bit about what you've built.

SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.

Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.

We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.

In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.

We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~550). Now we’re scaling the platform.

For more and to apply, see https://smarterdx.com/careers

The cost of homeowners insurance, especially in natural catastrophe prone areas, has skyrocketed in recent years. Annex is solving this problem with better digital infrastructure for executing the transaction. Our platform enables insurance agents to quote and bind policies within 90 seconds vs. the current multi-day phone/email/fax-based transaction that is the status quo.

We grew 4x in 2025 and anticipate similar growth in 2026. We've done the above after deploying <$1.5m in funding. We have significant and growing momentum on both the insurance distribution and insurance capital sides of our business; our challenge now is scaling our engineering team to support that progress.

We're in that exciting early stage, where someone can contribute foundational new pieces to core parts of our platform.

Reach out to Steve@pango.ai if you are interested or have any questions. We review applications immediately and move quickly.

Dashdoc is a SaaS Transport Management System for road freight. We help carriers and shippers run transport operations on one shared platform.

We’re hiring a product-minded engineer to help us expand in Belgium and the Netherlands. Local specifics: e-CMR mandates, digital waste regulations, Dutch/Flemish accounting standards, regional carrier workflows often block deals or deployments. Your job is to find those blockers and turn them into shipped product.

You’ll work directly with customers, sales, CSMs, and product. You’ll be able to spend time with carriers in Belgium and the Netherlands, watch users use the product, read contracts/regulations, then spec, build, deploy, and measure the features yourself.

Stack: React, React Native, Python/Django, Django REST Framework, PostgreSQL, Google Cloud. We use Shape Up, ship continuously, and use AI coding tools like Claude Code, Cursor, and Codex.

Good fit if you speak Dutch fluently, write clearly in English, like owning ambiguous product problems end-to-end, care about simple UX and clean code, and enjoy deleting code as much as adding it.

Kadoa is the web data layer for finance. We use coding agents to build, monitor, and repair deterministic data pipelines for investment firms, so they can make faster and better decisions.

All founders have spent years in the trenches writing web scraping and ETL code and still do it almost every single day. We are growing fast, have a drama-free and distraction-light environment, and try to minimize the distance between the code & data you ship and the customers who use it.

We are looking for people who share our passion for software craftsmanship, data, and AI. We're a lean remote team and are looking for low-ego generalists with high agency that can help us build a platform that combines the most intuitive UX with world-class accuracy and performance.

Open roles:

- Web Scraping Engineer: https://www.kadoa.com/careers/web-scraping-engineer

- Senior Software Engineer: https://www.kadoa.com/careers/senior-software-engineer

We're a consumer fintech with 20M+ users who trust us to budget, save, invest, and bank in one place. Profitable for 4+ years. And as of today, our average employee tenure is 3.6 years, a number you almost never see in startup tech, and one we're quietly proud of. People stay because the work is good, the people are sharp, and we've built something worth staying for.

Now we're building net-new consumer products from zero, and we're looking for people who love to tinker and build stuff to ship them with us.

The kind of person we're looking for: • Top fraction of a percentile in craft, the kind of good that's hard to fake • Builds for fun, not just for work. The kind who ships a working prototype over the weekend and can't help themselves • Comfortable owning 0 to 1 consumer products end-to-end • Allergic to politics, theater, and bureaucracy

What you get: • Remote, anywhere with reasonable timezone overlap (and for someone truly exceptional, we'll make async work) • Real scale from day one (20M+ users, real money, real consequences) • Compensation that beats the market. We pay well and we mean it. Base, discretionary year-end bonus, meaningful 401(k) match, and meaningful equity in a profitable, growing unicorn (the kind that's actually worth something) • Platinum PPO health benefits with Blue Shield, top of the top of the line, covering your entire family • A mission worth your time: make money simple, so people spend less time managing it and keep more of it • Small senior-heavy teams, direct ownership, no layers • Forthcoming with the business metrics that matter, so you always know how the company is actually doing • The startup perks done right: catered lunches, wellness stipend, team offsites, casual dress. The stuff that compounds when you're showing up engaged for years, not months • Profitable for 4+ years, so you build with conviction, not runway anxiety

Stack: python, claude, postgres, react.js /react native

Edit: we are in the process of rebuilding our career site to speak to how we hire (e.g. hunt, dont post, find the best). Just an FYI

Also, we carefully review every application. If we think there may be a fit, we'll reach out within a few business days. Either way, thank you for your interest in what we're building and for taking the time to connect with us.

Distru is the #1 ERP in the cannabis industry, $3B in annual sales flows through our platform, and most of the top cannabis brands and distributors in the US run their entire operation on us to stay compliant.

We're profitable, stable, and growing — no runway anxiety, and we're reinvesting into new product lines. We're an intrinsically motivated team that works without ego, is constantly learning, and genuinely cares about our people (5/5 on Glassdoor).

Distru is at an inflection point. We have deep market penetration in cannabis ERP, a new commerce layer (Distru Commerce — a B2B wholesale marketplace) live and growing, and a roadmap with a growing AI component. Our live AI Order Agent already lets buyers submit orders in any format from any source, killing manual data entry, the first of many bets on using AI to strip the repetitive heavy lifting out of running an ERP.

The role: You'll own mission-critical, full-stack features end to end — planning, design, implementation, testing — across every part of the product. You might work on AI-native features (order/purchase intake, smart product matching, systems that learn from user feedback), Distru Commerce storefronts and ordering, manufacturing and distribution workflows, cultivation mobile tools for the floor, or compliance integrations with state systems like Metrc. It's a high-ownership role: you'll partner directly with product, design, support, and our C-suite, and you'll get customers writing you personal "thank you" emails.

IPinfo is a leading provider of IP address data, including geolocation, VPN and residential proxy detection, mobile carrier data, and over 20 other context tags. Our API handles over 120 billion requests per month, and we also license our data for use in many products and services you’ve likely interacted with.

We are looking for a Data Engineer to work on our Places product (https://ipinfo.io/data/places), adding detailed location context to IPs from around the world. This work involves complex BigQuery SQL pipelines to process and clean diverse and messy source datasets. We value simple, readable code and look for subtractive solutions over bloat. We are building something completely new, so the work is very empirical we approach it with an experimental, iterative mindset. Geospatial skills/background is a plus.

Reach out to XXXX if you are interested. Please share a CV and tell us about your background and why this role is interesting to you.

Hi HN! I'm posting my own backfill, as I'm leaving MassChallenge. It's a hands-on Product/Tech leadership role: you'd own software engineering, data, AI, and IT.

I don't think I can afford hiring someone in north america, I'm not a company, this is a small project that'll take more than a year

I'm looking for someone who understands C/C++ and would be willing to learn C++20. The codebase is small (<100k lines), and you'll be working with me to complete a project. I'll help you learn C++20 and various tools. I don't mind if you know very little, but you'll need to understand every line you write and be able to explain it to me. You'll be expect to problem solve alone.

Email me something to look at. JurassicTyler@proton.me I don't need a resume. I rather look at code you written entirely yourself. Pick a specific file you think is interesting.
