Job description

Zof AI is seeking a Frontend Developer to own the console where engineers watch agent fleets work, review proposed fixes, and approve remediations. This role covers the full surface of our product interface: React and TypeScript in Next.js, real-time streaming views of agent runs, diff and evidence review flows, accessibility, and performance under heavy live data. If you have worked as a UI Engineer, React Developer, Web Developer, or Product Engineer, this is that discipline at Zof AI. The ideal candidate has shipped data-dense product interfaces, treats latency and accessibility as product requirements rather than cleanup work, and wants engineers to trust what the console shows them.

• Own accessibility and keyboard-driven workflows so long review sessions stay fast.
