If you've shipped complex front-end platforms used by many teams and love balancing craft with impact, we'd love to talk., * Own the front-end architecture blueprint (React, TypeScript, state management, routing, data-fetching, build tooling).

• Define standards for component libraries/design systems (atoms/molecules/organisms, theming, tokens, typography, color, motion).
• Establish performance, accessibility (WCAG 2.2), internationalization, and security guidelines for all UI code.
• Select and govern front-end tooling: bundlers, linters, test frameworks, CI/CD gates.

Framework & Design System Leadership

• Architect and maintain a multi-app UI framework (design tokens, shared components, templates, page scaffolds) enabling rapid product delivery.
• Drive component API design and versioning, documentation, and governance (RFCs, ADRs).

Delivery & Technical Leadership

• Lead technical discovery and spikes; write architectural ADRs; unblock teams with reference implementations.
• Review solution designs and PRs for architecture compliance; coach teams on best practices.
• Collaborate with Backend/Platform Architects on contract design (GraphQL/REST), caching, and edge delivery (CDN).
• Guide migration roadmaps (legacy UI React/TypeScript), including strangler patterns and incremental rollout.

Quality, Reliability & Observability

• Define quality bars (unit/integration/visual/regression tests), error handling patterns, and performance budgets.
• Instrument Real User Monitoring (RUM) and UX analytics; set dashboards for Web Vitals (LCP, FID/INP, CLS) and Core UX KPIs.
• Champion secure front-end practices (XSS mitigation, CSP, OAuth/OIDC flows, CSRF, SSRF prevention on proxies).

Stakeholder & Governance

• Facilitate architecture reviews; align with product strategy and quarterly OKRs.
• Contribute to hiring, mentoring, and professional development of front-end engineers.

Do you have experience in TypeScript?, * Expert React/TypeScript: advanced component patterns, hooks, context, Suspense, server components (where applicable), state management (Redux Toolkit, Zustand, React Query).

• Web UI Architecture: modular monorepos (e.g., Nx/Turborepo), micro-frontends (Module Federation), SSR/SSG (Next.js), edge rendering.
• Design Systems: token-driven theming, accessibility-first components, documentation (Storybook), semantic HTML and ARIA.
• Performance & Accessibility: deep knowledge of Web Vitals, profiling, code-splitting, lazy-loading, image optimization, and WCAG compliance.
• Testing & Tooling: Jest/Vitest, Testing Library, Playwright/Cypress, visual regression; ESLint/TypeScript rules; CI/CD pipelines.
• Security: threat modeling for the front-end, secure auth flows, secure storage, CSP.
