NeuralFrame | Senior Backend Engineer, Medical Data Pipeline (Python + Rust) | REMOTE (US only, US time zones; no visa sponsorship) | Full-time | $170k–$210k + 0.1%–0.25% equity

We build software that hospitals, cancer registries and researchers use. You'd own the pipeline that pulls data from hospital systems and transforms it for analytics and research.

Where Rust fits: part of our hospital data acquisition layer, the code that talks to hospital systems, is written in Rust. You'd work on both sides: Rust where performance and correctness matter most, async Python for the rest of the pipeline. Rust experience is a strong plus. Whether you learned it at work or on your own, we want to hear what you built with it.

Stack: Rust, async Python (mypy, pytest, ruff, uv), PostgreSQL and MongoDB, Dagster, Terraform/OpenTofu, AWS (ECS/Fargate, RDS, Lambda, S3), GitHub Actions.

You'll need 5+ years building backend services or data pipelines in production (retries, idempotency, schema design and migrations, well-tested and typed code) and strong Python and SQL. No healthcare background needed.

Apply: https://wellfound.com/jobs/4829721-senior-backend-software-e.... In your note, tell us in a few sentences about one pipeline failure you traced (what broke, how you found it, what you changed) and, if you've written Rust, what you built with it.

3x founding/first engineer with 15+ years shipping products from zero to scale. Most notably: founding engineer at EverAI — joined at zero, built nearly every core feature, grew to 20M users and $5M/month revenue. Pioneered production AI pipelines across LLMs, image generation, voice synthesis, and video — not API wrappers, full systems.

Also: first eng at Shogun (YC W16, became category-leading Shopify app), CTO at AirHelp (concept to launch in 5 months), founded and scaled a 20-person dev agency. Most recently built an ad platform at TurbaMedia from zero to $24M+ annual spend in 6 months.

Looking for: Early-stage startup where I can own product areas and work directly with founders. I've built entire products solo — I don't need hand-holding, I need interesting problems. Fully remote.

Propel Labs | Staff Full-Stack Engineer, Quality & Delivery | Remote (North America hours) | Full-time | https://propellabs.ai

Hello HN, Lisa here from Propel! We're a bunch of interdisciplinary builder-maker-designers leading a venture studio and building software for mining and deep-tech companies. Think IDEO for AI: a small senior team, direct CEO involvement, technical depth married with design craft. We are not a dev shop and not a consultancy, we're not about scope or hours, we're only about outcomes. We embed through the lifecycle of challenges and the same senior people stay on the problem.

AI agents have made engineering throughput cheap, so senior judgment is now the scarce asset: what to build, what to gate, what to trust to production. We're looking for an experienced engineer to join our small crew and play a ~70/30 build-to-lead role: - Raise the team’s bar without bureaucracy - Ship production code - Be the human PR review - Own the quality delivery system as a product - Ship spec-first - Orchestrate AI at staff level

Stack: TypeScript, React, Python, PostgreSQL, ECS/Lambda, Terraform.

We work on fascinating projects with physical implications to the world but more importantly we just really don't work with a*holes, I wake up happy to see my colleagues, the crew loves to laugh and we walk the walk.

Full role details: https://docs.google.com/document/d/1R7rPplGTziBmvnKSocRRQ5Pg...

Email lisa@propellabs.ai with a PR, design doc or postmortem you're proud of, and why this role. Always happy to jump on short calls for a mutual sus-out. It's a call for adventure, after all.

Cleverbase | https://cleverbase.com/ | The Hague, Netherlands | ONSITE (hybrid) | Full-time

Cleverbase runs an API platform for online trust: qualified e-signatures, PKI, digital identity and high-assurance identity onboarding for European organisations. We’re now building towards the EU Digital Identity Wallet and the European Business Wallet. Helping customers design and ship their solutions on our platform matters as much to us as building the platform itself.

As a Qualified Trust Service Provider under eIDAS, what we ship has to be demonstrably correct, auditable and secure, and we still deploy frequently. We go beyond compliance by applying modern cryptography to better protect personal data, because our mission is everyone secure online.

Stack: JVM (Scala with Cats/Cats-Effect, http4s, fs2, doobie), gRPC, Postgres and HSMs for the trust services; TypeScript (React, NestJS, oRPC, Drizzle, Playwright) for web; standards like JSON/XML/PDF signatures and OpenID. Experience with this exact stack isn't required, but interest in cryptography or digital identity is.

Roles currently available:

Web Engineer (Medior): https://cleverbase.com/en/careers/web-engineer-medior/

Flowstate (London, UK) — Founding Engineer — TypeScript / React / Postgres / AI

Flowstate (https://www.flowstate.inc) is building infrastructure for the emerging human + AI workforce.

Companies are rapidly adopting Claude, ChatGPT, Cursor, Copilot and internal agents, but most still have very little idea what that AI is actually doing, what it costs, what work it contributes to or whether it is making the organisation better.

We’re building the systems underneath that: an AI router and proxy, native macOS and Windows apps, attribution infrastructure that connects AI activity back to work and tools for understanding how humans and AI should operate together inside a company.

We’re a small early-stage team and this is a genuinely broad founding engineering role. You’ll work across product, infrastructure, integrations, desktop apps, AI systems and whatever else needs building. We’re looking for someone who has worked in an early-stage startup before and actually enjoys the pace, ambiguity and ownership that comes with it.

Details: - Location: London, UK - Working style: Hybrid, with regular time together in the office - Salary: £100k–£120k - Equity: 0.5%–1.5% - Benefits: Gym membership, breakfast and flexible hours - Role: Full-time

Apply: https://www.flowstate.inc/careers/

Fig | Founding Engineer | San Francisco (hybrid) | $220k-$280k + meaningful equity

Fig is hiring its founding engineer.

Fig builds software for industrial ingredient processors, the companies between farmers and the food brands you buy. Most of them still run on paper binders: production schedules, sanitation checks, quality logs. Tech has mostly ignored them.

This is a high-ownership seat. You'll work directly with the founders, who come from food, to build a platform that pulls together fragmented food-industry data, then the AI layer on top of it. Think Glean for the food industry. Customers who signed on as design partners a year ago are still here and still shape the roadmap.

Stack: Kotlin, React, TypeScript, GCP, Postgres, Terraform.

Fig is collaborating with Scout (https://www.scoutintro.com) to meet engineers. Book a coffee chat to learn more: https://calendly.com/lucia-scoutintro

RealResponse | Product Engineer | REMOTE (US) | Full-time | https://www.realresponse.com

We build software used across college athletics, professional sports, higher education, and other organizations, from reporting and compliance to live event operations. We're a team of < 15 people, with no venture capital, and profitable. This means we get to make decisions for our customers and our team, not for investors. Rails is at the core of everything we build, and we keep reasonable hours and a codebase we're proud of.

We're looking for someone who solves problems across the board: building and improving our applications, shaping products, internal tools, fast prototypes, and the systems that keep quality and security high. You'd own problems end to end, from understanding what the customer actually needs to shipping the fix.

On the AI side, we want someone who knows how to:

- Evaluate new models as they ship, and pick the right one for the job (fast and cheap vs. most capable)

- Design agents and multi-agent workflows with tool use, and know when a simpler approach is better

- Build retrieval that stays accurate as the underlying content changes (RAG, embeddings, search)

- Measure quality with evals and observability, so changes are proven rather than guessed

- Keep AI features fast, reliable, and cost-effective under real production load

- Handle AI security properly: prompt injection, data isolation between customers, and sensitive data

Stack today: Rails 8, Hotwire, Hotwire Native, Postgres, AWS. Rails experience helps but isn't required. What matters more is a strong grasp of solid engineering practices and principles, and the judgment to use the right tools to solve the problem.

To apply: email jobs@realresponse.com with subject "Product Engineer: [your name]". Include a link to something you built, a few sentences about a problem you solved end to end, your salary expectations, and your CV.

ALBERT | REMOTE ALMOST ANYWHERE IN THE WORLD| Hiring principal and distinguished engineers to build net new products | up to ~ $750k Hiring: exceptional consumer product engineers at Albert.

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

InfoHawk | Software Engineer | London, UK or NYC | HYBRID (UK or US), occasional onsite | Full-time | https://www.infohawk.com

Fraud reaches people through ads, cloned brand sites, counterfeit shops and AI-generated video, and it moves faster than any manual review. InfoHawk detects it while it is still running, correlates it across platforms and formats, and surfaces it early enough for our customers to act. We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...

You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.

We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.

Opaxa | Founding Engineer, Forward Deployed (full-stack) | San Francisco Bay Area preferred, REMOTE (US) considered | Full-time | $175K–$225K + 0.5%–1.5% equity | opaxa.com

Every business with many locations already has systems that record what happened yesterday. None of them tell the manager what to do today. Opaxa does. It reads the systems a business already runs, learns how that operation actually works, and puts the right decision in front of the right manager: how busy tomorrow will be, who to schedule, what to order, which invoice overcharged you. Then it tracks what each decision earned.

Our founder runs a restaurant company with more than 40 locations and over 750 employees. Opaxa was built inside it to solve its own problems, and it runs there every night. We're well funded and now expanding to other multi-location operators: restaurant groups, stadiums and campuses, hotels, retail.

You'd be the second engineer, working with our founding engineer, who owns the architecture, and with the sales and product team. You'd take new features from spec to production, spend real time with the managers who use them, and turn what they tell you into shipped changes within days. As we bring on new clients, you'd lead getting them live. TypeScript/React, Python, Postgres, AWS, and AI tools every day.

This is an early, high-intensity role for someone who wants a lot of ownership and to move fast. US work authorization required. No agencies or contract firms.

To apply, email colton@opaxa.com with the subject "Forward Deployed: your name, your city" and include: your resume or LinkedIn; a link to something you built that real people use, and what you personally did on it; two or three sentences on a time a user's feedback changed what you shipped; and where you're based. We read every email.

Footprint | Rust Engineers (Backend, Infrastructure, Security) | New York, San Francisco | ONSITE | VISA (case by case) | $180K-$260K + equity

We build Percy, an agent that runs financial-crimes investigations for banks and fintechs. It clears false positives, escalates real risk, and writes the case narrative and audit record a regulator will read. Under it sits four years of identity infrastructure: verification, an AWS Nitro Enclave-backed vault for PII, and the APIs our customers call directly. The backend is Rust.

We're hiring three Members of Technical Staff:

- Backend: the Rust APIs and services behind verification, vaulting, and the checks Percy runs. Production Rust is ideal; deep systems experience plus a real wish to learn it also works. Crypto or systems-security background counts for a lot.

- Infrastructure: own agent compute, isolation, deploys and observability across Rust services and long-running agents. Rust, Postgres/Aurora, AWS (ECS/Fargate), Pulumi/Terraform, Datadog, OpenTelemetry.

- Security: protect identity data we vault on behalf of regulated banks and fintechs, and prove to auditors every step was done right.

Small, senior team. Backed by QED, Index and BoxGroup. Customers include FDIC- and OCC-regulated banks plus Bilt, Nuvei and MoonPay.

Apply: https://jobs.ashbyhq.com/footprint. I'm the recruiter and will answer questions in this thread.

Mattermost | Remote (US and Canada) | FT | Multiple roles

Mattermost (https://mattermost.com) is an open-core collaboration and workflow automation platform for air-gapped, on-prem and private clouds. Our customers are in defense, intelligence, security and critical infrastructure, including the USAF and NASA. Y Combinator led our Series B, their largest open-source investment at the time.

Both openings are full stack on the core platform: Go backend, React/TypeScript frontend, PostgreSQL and Redis. The codebase is public (https://github.com/mattermost/mattermost), so most of what you build is too. We would rather hire people who ship and own complex software end to end than chase an exact stack match, so any systems or backend language and any frontend stack counts. What we look for in both roles: REST and WebSocket APIs with real networking fundamentals (HTTP, connection lifecycle), and relational databases including schema design and query optimization.

We use coding agents daily (Claude Code, Cursor, and others) at every stage of the work: planning, building, reviewing, testing, and shipping. We treat that as core craft rather than a shortcut around the fundamentals. If you have a track record of shipping and owning complex software end-to-end, we want to hear from you.

Senior Full Stack Engineer $142,723 - $172,723 USD Architect and ship full stack features end to end, own the testing strategy for what you ship, and build internal tooling and testing infrastructure that makes the rest of the team faster. You will work without close supervision and hold the security and compliance bar our customers require. Nice to have: distributed systems and high availability architecture, regulated-environment security, open-source contributions, experience on remote-first teams.

Join our team: https://job-boards.greenhouse.io/mattermost/jobs/5379251008

Staff Full Stack Engineer $172,724 - $227,135 USD Set technical direction for the platform rather than for a feature area: architecture and roadmap across the stack, the standards for how the org uses coding agents, and the strategy for internal tooling and testing. You will influence direction across teams, partner with security and compliance on it, and mentor senior engineers. Nice to have: staff, principal or tech lead experience elsewhere, open-source maintainership, FedRAMP or ITAR familiarity, defense or critical infrastructure background.

Join our team: https://job-boards.greenhouse.io/mattermost/jobs/5405811008

Both roles have Canadian postings: https://job-boards.greenhouse.io/mattermost
