Someone has to trace a feature across every layer and find where it actually breaks, and that someone is you.</p><p>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.</p></section><section class="rd-section"><h2>What you’ll actually do</h2><ul><li><b>Build with frontier models</b> on real end-to-end tasks: wire a UI to an API, model the data, and see how far the model gets.</li><li><b>Trace the feature across layers</b> to find where it breaks: stale state, leaky endpoints, and migrations that don't survive contact with real data.</li><li><b>Write the working version</b> when the model falls short, sound from the component down to the schema.</li></ul></section><section class="rd-section"><h2>Roles this fits</h2><p>Common backgrounds: Full-Stack Engineer, Web Developer, Product Engineer.</p></section><section class="rd-section"><h2>What we look for</h2><ul><li>Professional or serious open-source experience shipping full-stack applications.</li><li>Comfort across the stack; most tasks span a JavaScript front end, an API layer, and a database.</li><li>Clear written English: your explanations are the training signal.</li><li>No degree required.
