Senior Fullstack Engineer (React / Go)

Responsibilities:

• Build product features end-to-end: React/Next.js frontend, Go API, and the data model behind them.
• Build data-dense interfaces: live video streams, analytics dashboards, large tables and annotation tools.
• Grow our shared UI component library and design system so every app looks and works the same.
• Make apps fast and dependable: data fetching and caching, loading, empty and error states, and accessibility.
• Write the Go endpoints your features need, against our published service contracts.
• Own quality with unit and end-to-end tests, and lead reviews and mentoring on the frontend.

Requirements:

• 3+ years building web applications, including production React and TypeScript.
• Strong with Next.js, React Query (or similar) and state management (Redux Toolkit or similar).
• Experience with a component library and design system (MUI, Radix, Tailwind or similar).
• Backend experience building APIs; Go preferred, or strong experience in another typed language and willingness to learn Go.
• Experience with data visualisation and large data sets in the browser (charts, virtualised tables).
• Experience with video playback or streaming in the browser (e. g., HLS) is a plus.
• A strong eye for UX and detail, and the judgment to ship incrementally.
