Fractional AI | https://www.fractional.ai | Full-time in SF, NYC, Raleigh-Durham, Dubai (ONSITE) | Software Engineers, Forward-deployed PMs, and more

Fractional AI operates at the forefront of applied AI, and we measure our success by the business outcomes we deliver in production — not by checking boxes on a SOW. We build production-grade AI systems that optimize core operations, automate internal workflows, and improve customer experiences. Every system is designed explicitly against clear business goals and North Star metrics (revenue growth, cost take-out or avoidance, churn reduction, etc.). Our role is to enable our customers to get past POCs and experiments into robust, real-world systems that reliably create value.

Stackable | Product Engineer - Web & UI | Remote (Germany/UK) | ~20 people | Full or part-time

We build an open source data platform on Kubernetes. The product (Stackable Data Platform - SDP) bundles 12+ open source data tools (Trino, Apache Kafka, Apache Airflow, Apache Superset, etc.) and makes them work together. Right now everything is Infrastructure-as-Code only. We need someone to build a UI layer on top.

No mockups, no Figma, no product roadmap waiting for you I'm afraid, just a bunch of ideas :) We're all backend people and need someone to own this end to end. Play around with our product stack, figure out what customers actually need, build it.

Stack (because we got started without you...): Svelte/SvelteKit, TypeScript, TailwindCSS. SDP itself is Rust, Java, Python on K8s. Three releases a year. Not SaaS. Quality matters.

100% remote, Germany (UK possible) only, no other countries, sorry. No Scrum, minimal meetings. Interview process is usually just two conversations. The position isn't on our homepage yet as I'm on vacation. Send a mail to recruiting@stackable.tech and I'll get back to you next week. Please mention HN in your mail. My personal mail is also in my HN profile. I'm the Co-founder and CTO.

New Lantern | https://newlantern.ai | Software engineers (backend and generalist product engineers, founding security engineer) | Full time in San Francisco, CA (ONSITE)

New Lantern is building an AI radiology resident—think Cursor for radiologists. Our application integrates the three software tools radiologists use all day [1], together with AI, to create a platform that saves radiologists toil and lets them focus on reading images and finding disease.

We are a series A startup with ~15 engineers (~30 total staff), have live customers generating revenue, several years of runway, and are backed by Benchmark, Anthropic, and other great investors.

We're hiring for several engineering roles. You'll work directly with our founder/CEO, our staff radiologists, and our end users to build a product that radiologists rely on daily. You'll have real ownership and autonomy, and ship meaningful work frequently.

I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai. I've already hired one engineer from HN this year and interviewed many more!

[1] a radiology image archive & viewer, a medical report dictation system, and work management system

Kinelo | kinelo.com | Product Engineering (Backend+AI focus) | San Francisco | Onsite (with flexibility)

We are hiring two Product Engineers to join us in our newly opened office in SF. We're small and early and you'll help shape team culture.

Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.

Our #1 hiring criteria for this position is immense software wisdom, the kind not yet encoded in the weights of an LLM. We are not looking for artisans to meticulously craft single lines of code. We're looking for software engineers excited to use the leverage that AI offers for code production to permit focus on higher order technical architecture, product requirements, and user needs.

We're looking for enough experience that indicates accumulated wisdom in shipping and maintaining reliable, scalable software, solid CS fundamentals, experience taking products from 0 to 1, and versatility.

Our current tech stack includes TypeScript, a managed container service, Postgres, and Redis. But we are adaptive and you should be too. We highly value software engineering and computer science fundamentals and experience with other languages like Go, C++, Python is valued.

Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).

Please email us at jobs@kinelo.com. If you want to stand out, tell us how you think the job of a software engineer is changing. There's also a full JD here: https://job-boards.greenhouse.io/kinelo/jobs/4205846009

Prior Labs | Berlin / Freiburg / NYC | ONSITE | Full-time | Multiple Roles

Tables power every clinical trial, financial model, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.

The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.

- ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.

- Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.

- Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.

- ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.

Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.

20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. With backing from leaders at Hugging Face, DeepMind, and Black Forest Labs, XTX Ventures & Balderton.

AI x Healthcare Startup | Boston, MA Onsite | Full-time | Early Engineer

We're looking for a backend-leaning fullstack dev. You will be one of the first engineers outside of the founding team. Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.

We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!

We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.

You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. 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!

Luminate | Software Engineer | Onsite Los Angeles, CA | Full Time

Luminate is the entertainment industry’s preeminent data and insights partner, serving as the single source of truth for record labels, film studios, talent agencies, and every part of the music and entertainment ecosystem.

The team's stack is Java w/ Spring, React w/ Typescript, and SQL w/postgres, and snowflake. We use playwright for e2e testing and deploy our infra on AWS.

The team is relatively new (around 3 years old) but is working on an older codebase with plenty of tech debt. Luckily we actually _do_ get time to address our tech debt and take the time to leave our code better than we found it, so it's getting better all the time.

We have an oncall rotation but getting paged is pretty rare.

Volunteer (unpaid) | remote anywhere | Infrastructure Engineer | Part time | https://getinstaprep.com

We'd like to feed the world through AI, here is our product concept:

https://taonexus.com/publicfiles/mar2026/render%203-2.webp

https://taonexus.com/publicfiles/mar2026/render%204.webp

We currently donate money to food banks and would like to set up end-to-end infrastructure so we could deliver free food to people's homes. Our concept is that AI does all the work (including farming) and gives away free goods and services. Where this runs into problems is the question of who's going to make and distribute food and how people are going to get it. While we haven't figured out all parts of food delivery we'd like to work on the distribution channel. We think it's very important.

What we're looking for is someone who is passionate about owning network infrastructure in people's homes and would like to help run the software stack, since at the moment AI is not talented enough to autonomously run the full infrastructure stack. This is an unpaid volunteer position.

What you would be in charge of is food distribution algorithms, equality, fairness, and the long-term future for humanity.

You can email me directly at: rviragh@gmail.com - please mention relevant volunteering or organizations you support.
