What We're Looking For

???? ???????????

● 5+ years skilled 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 — strong 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 clear view on what's worth testing and what isn't

Working with people

● Experience managing or leading a frontend team, or acting as technical anchor on a squad

● Track record of mentoring engineers and improving how a team works

● Strong collaboration with design and product — comfortable in a design review, not just a standup

● Clear written communication — RFCs, architecture notes, documentation

???? ?? ????

● Portfolio of premium, creative or Awwwards-style work — this weighs heavily

● Open-source contributions, especially to component libraries or developer tooling

● WebGL or shader experience beyond Three.js basics

● Design systems at scale, or a published public design system

● Headless CMS architectures

● Frontend observability — error tracking, RUM, session
