Senior Frontend Engineer

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."
