Job description
Run BiOS serves open models through one OpenAI-compatible API, priced per million tokens, and fine-tunes custom models on dedicated GPUs — customers own the weights. As an AI Product Engineer you build the surfaces that make that engine feel inevitable: the platform console, the API experience, the model catalog, the pricing calculator, and the docs developers read before their first call.
What you'll do:
Design, build, and ship end-to-end features across the Run BiOS console and public surfaces — from model catalog to billing to onboarding.
Shape the developer experience of one OpenAI-compatible API: error messages, streaming behaviour, SDK ergonomics, quickstarts.
Own frontend architecture in TypeScript, React, and Next.js, and the API boundaries behind it.
Productize what research and applied ML land — new models, new fine-tuning methods, router improvements — as visible, usable features.
Instrument what you ship: activation, funnels, and latency budgets, and act on what they say.
Talk to users and read support threads. Close the loop between what developers hit and what we build next.
What you bring:
At least 5 years shipping production web applications, with strong TypeScript and React.
Full-stack comfort: you can design an API, write the migration, and polish the UI it drives.
Genuine fluency in LLM concepts — tokens, context windows, adapters, fine-tuning — even if you have never trained a model yourself.
Product judgment: you can argue for a scope cut, and be right.
Clear writing. Our docs and interface copy are part of the product.
