Frontend Engineer
About this role
Overview Models ship UI that renders in the demo and breaks everywhere else: state that desyncs on the second render, an accessibility tree no screen reader can follow, a layout that collapses the moment real content arrives. Someone has to judge the interface a user actually touches, and that someone is you. As a Frontend Engineer you'll stress-test how models build components, state, and end-to-end web features, expose where the UX and correctness break, and write the answers a strong frontend engineer would ship. What you’ll actually do - Probe frontend reasoning across components, state management, accessibility, and rendering, and see where the model's UI falls apart. - Find the failures that matter: stale state, re-render bugs, broken a11y, and layouts that break under real data. - Write the correct implementation when the model falls short, with the UX and edge cases handled. Roles this fits Common backgrounds: Frontend Engineer, UI Engineer, Web Developer. What we look for - Professional or serious open-source experience building web UIs. - Comfort with a modern framework and CSS; most tasks assume React, TypeScript, or similar. - Clear written English: your explanations are the training signal. - No degree required. We care about what you can do, not where you learned it. How it works Apply Qualify Work & get paid Compensation Up to $150+/hr depending on task difficulty and specialization.
