Senior Frontend Engineer

Job description

In this role, you will lead the frontend engineering at Umbrel, and own major product surfaces in umbrelOS (web UI), our first-party apps, and our website. We hope you are someone who: - Treats Figma as a contract you’ll honor in code, and you’ll improve it when the reality demands. - Ships polished, accessible interfaces in React + TypeScript (Tailwind, Shadcn, Radix). - Sweats the last 5%: empty states, errors, skeletons, loading strategies, and microcopy that reduces cognitive load. - Uses motion to communicate state (not decorate it): consistent easing/durations and meaningful transitions. - Thinks in systems: API-design, theming, responsive scales, and components that age well. - Writes clear, readable code and tests, and leaves the codebase calmer than you found it. - Can take a vague problem → write a short design doc → prototype in code → ship in small, reversible steps. - Partners with design early: you’ll prototype, tweak spacing/typography/easing, and treat copy as part of the UI. - Communicates crisply in writing (we’re async-first) and gives kind, candid feedback. - Has strong product judgment. Knows when to refine and when to press "ship."
