What We're Looking For

???? ???????????
● 5+ years professional frontend experience, with meaningful time at senior or lead level
● Advanced React — can debug reconciliation, rendering behaviour and concurrent features, not just use them
● Advanced Next.js — App Router vs Pages, Server Components, CSR/SSR/SSG/ISR, caching layers, streaming
● Expert HTML, CSS and TypeScript — robust typing habits and CSS that holds up without a framework propping it up
● Deep browser knowledge — event loop, rendering pipeline, layout and paint, memory behaviour
Motion and craft
● Proven experience building highly animated, interactive websites choreographed motion, not just CSS transitions
● Proficiency with GSAP, Framer Motion, Three.js or comparable animation and WebGL libraries
● Hands-on with interaction-heavy UI patterns — drag-and-drop, node graphs, virtualised boards and canvases (dnd-kit, React Flow or similar)
● Genuine Figma-to-production fidelity — spacing, type, easing, timing
● An eye for detail that catches what a designer would have flagged anyway
Platform and reusability




● Built reusable, generic component systems that survive contact with multiple teams
● Built UI theming systems from scratch — tokens, theme switching, multi-brand support
● Authored npm libraries or SDKs — API design, versioning, tree-shakeable builds, TypeScript definitions, migration guides
● Comfortable with monorepo tooling and component documentation (Turborepo, Nx, Storybook or equivalent)
● Build complex, stateful interfaces — drag-and-drop kanban boards, visual workflow builders and pipeline views — that stay fast and intuitive as the data grows

???????
● Performance optimization — Core Web Vitals (LCP, CLS, INP), bundle budgets, code splitting, image and font strategy
● Accessibility — semantic HTML, keyboard navigation, focus management, WCAG AA baseline, reduced-motion support
● Cross-browser and cross-device compatibility as a habit, not an afterthought
● Testing discipline, with a clea
