Full Stack Engineer

Overview Models can scaffold a whole app in one shot: front end, API, and database, all of it looking right. Then the state goes stale, the endpoint leaks data, and the migration bricks production. Someone has to trace a feature across every layer and find where it actually breaks, and that someone is you. As a Full Stack Engineer you'll run frontier models on real end-to-end tasks, analyze what they build across the stack, and write the judgments that teach the next generation to ship features that hold together.

What you’ll actually do Build with frontier models on real end-to-end tasks: wire a UI to an API, model the data, and see how far the model gets. Trace the feature across layers to find where it breaks: stale state, leaky endpoints, and migrations that don't survive contact with real data. Write the working version when the model falls short, sound from the component down to the schema.

Roles this fits Common backgrounds: Full-Stack Engineer, Web Developer, Product Engineer.

What we look for Professional or serious open-source experience shipping full-stack applications. Comfort across the stack; most tasks span a JavaScript front end, an API layer, and a database. Clear written English: your explanations are the training signal. No degree required. We care about what you can do, not where you learned it.

Compensation Up to $150+/hr depending on task difficulty and specialization. Many contributors add $100k–$200k a year; some make it their full-time income.
