• APIs & data: Collaborate with Backend on REST/GraphQL contracts; implement data-fetching patterns (React Query/TanStack, SWR) and error/empty states.
• Observability: Instrument telemetry (OpenTelemetry/console events), track client error rates and performance dashboards, and iterate based on data.
• (Senior) Tech leadership: Lead design docs/RFCs, make framework/library trade-offs, guide code reviews, and mentor junior/mid engineers.

• Mid-level: 3-5 years building production web apps with React, TypeScript/JavaScript, HTML, and CSS.
• Senior: 5-8+ years, including leading feature delivery across services/teams and mentoring peers.

• Hands-on with testing (Jest/Vitest, Playwright/Cypress) and CI/CD.
• Practical accessibility skills (semantic HTML, ARIA, screen readers, focus, contrast).

Preferred Qualifications:

• Next.js (App Router), React Server Components, streaming, and incremental static regeneration.
• Experience with design systems (tokens, Storybook), visual regression testing, and component governance.
• Micro-frontends (Module Federation) or monorepo tooling (Nx/Turborepo).
• Internationalization (i18n) at scale.
• Observability (Sentry, OpenTelemetry, New Relic) and experimentation/analytics.
• Edge runtimes/CDN strategies (Vercel/Cloudflare), plus familiarity with WebAssembly/WebGL when applicable.
• Interest in applying AI/ML to improve UX or DX (e.g., content suggestions, automated testing).
