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.

Ojin | Lead Platform Engineer | HYBRID (Berlin) or REMOTE (CET ±2h) | Full-time

Hi HN! I'm Seema, part of the team at Ojin, and we're looking for our next Lead Platform Engineer.

We build AI agents that look and sound human - real face, real voice, real-time conversation. The kind of thing that makes people ask if it's actually live the first time they see it. Getting there means solving latency at a level most infrastructure can't touch, running custom frontier models for lipsync and face generation, and orchestrating all of it live across a globally distributed GPU fabric we own and operate ourselves.

This isn't a role where you maintain what someone else built. The hard problems are still open: dynamic routing and load balancing across thousands of concurrent GPU servers spanning multiple clouds and regions, keeping latency low enough that conversation feels natural, and deployment pipelines that can keep up with a product that's moving fast.

You'd set the technical direction for all of it, working directly with the founders on a 15-person team. No layers between you and the decisions that matter.

If you've worked on distributed systems at scale, care about how things are built and not just that they work, and want real ownership rather than a slice of someone else's architecture — we'd love to hear from you.

Stack: AWS, TypeScript or Go, Terraform/Pulumi/AWS CDK, Docker, serverless architectures.

Looking for: 5+ years hands-on AWS in production, strong IaC, multi-cloud experience, low-latency systems, and startup experience.

We're not able to offer relocation or visa sponsorship. If you're already in Berlin, this is a hybrid role. If you're elsewhere, we're open to fully remote within CET ±2h. Applications outside these criteria won't be progressed.

Apply or read more at https://ojin.ai and please mention you found us on Hacker News in your application. We're also hiring across sales and marketing.

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.

Senior Frontend Developer: build the onboarding flows, data import tools and setup wizards that get new customers live fast. Angular SPA with 3,500+ components and AG-Grid; we move to new Angular versions within weeks of release.

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.

Rebar | Software Engineers (Product, Applied AI, ML Infra, Data Platform) | ONSITE 5 days/week, New York City (union square area!) | Full-time | $150k–$260k + equity | https://jobs.ashbyhq.com/rebar

We build AI estimating software for commercial HVAC, plumbing, and electrical contractors. Before bidding on a job, a contractor or estimator has to count every duct, fitting, diffuser, and piece of equipment across a set of construction drawings that can run to thousands of pages. We speed this up by ingesting the drawings, detecting the equipment schedules, finding symbols, and producing a priced takeoff that the estimator reviews and corrects in a collaborative canvas editor. We have strong PMF and raised a $14M Series A earlier this year.

It may not sound sexy, but it actually is!! There are a ton of hard and interesting engineering challenges. Just to highlight a few:

* very dense document drawings with a realtime collaborative canvas editor (think 50k DOM elements and up) * segmentation models (and many more) whose output has to become geometry a user can interact with * gpu inference across hundreds of concurrent jobs * dynamic analytics and chart generation from agentic workflows custom built for estimators

Open roles:

* Software Engineer, Product ($180k–$240k): https://jobs.ashbyhq.com/rebar/5ab49c2d-9a70-4723-9217-7704a... * Software Engineer, Applied AI ($150k–$250k): https://jobs.ashbyhq.com/rebar/ad41a627-d9a4-49a4-a1b4-f7202... * Software Engineer, ML Infrastructure ($200k–$260k): https://jobs.ashbyhq.com/rebar/ead8df0c-b6da-4e79-90d0-99651... * Software Engineer, Data Platform ($170k–$220k): https://jobs.ashbyhq.com/rebar/c227ea05-98f8-4a08-9760-f7e3c...

Our agents operate payer portals behind MFA, green-screen terminals over SSH, and Windows desktop software, where some actions are irreversible. They run on a deterministic orchestration layer we built in-house, with model calls as bounded steps, not the control loop.

Stack: TypeScript/Node.js, Playwright, computer-use agents, Claude, Postgres, Azure, K8s.

You'll get to own the core platform end to end and make the real architecture calls: resilience to portal changes, exactly-once guarantees, observability, and cost per run.

Team: Founder from AWS, the former UnitedHealthcare CIO, advisors from Microsoft Research and Shopify's AI team, and a remote engineering team in-flight.

Please write us at careers@tahoma.io with your resume and one thing you've shipped. You can see more at https://www.tahoma.io/careers

You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.

This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.

We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!
