Role summary
Lead the design and development of modern, high-performance web experiences using React and the broader front-end ecosystem. This role is front-end focused, partnering closely with Product, UX, and backend/platform teams to deliver cutting-edge UI capabilities and set engineering standards.
Job responsibilities
- Lead development of complex, user-facing web applications using React + TypeScript , owning the front-end architecture and delivery approach.
- Partner with UX/Product to translate designs into polished experiences; influence requirements with feasibility, performance, and accessibility considerations.
- Establish and evolve front-end standards: component architecture, state management, routing, code conventions, and testing practices.
- Build using EXDS UI foundations: design system / component library , theming, responsive layouts, and cross-browser compatibility.
- Ensure secure client-side patterns: safe auth flows, token handling guidance, secure storage, and protection against common web vulnerabilities.
- Collaborate with backend teams on API contracts ( GraphQL/REST ) and advocate for front-end friendly patterns (pagination, filtering, error models).
- 8+ years professional software engineering experience with significant depth in front-end web development; experience leading projects and mentoring engineers.
- Expert-level React proficiency (hooks, component composition, context, rendering behavior, concurrency-related patterns where applicable).
- Strong TypeScript skills (types-as-design, generics, strictness strategies) and modern JavaScript fundamentals.
- Deep experience with modern front-end tooling: Vite/Webpack , Babel/SWC, npm/pnpm/yarn, monorepos (optional), and build/release pipelines.
- Strong CSS skills: responsive design, CSS architecture (CSS Modules, CSS-in-JS, or utility frameworks), theming, and consistent styling at scale.
- Advanced testing practices: Jest/Vitest , React Testing Library, Playwright/Cypress for E2E; test strategy ownership.
- Accessibility expertise: WCAG/ARIA , keyboard navigation, screen-reader considerations, and automated + manual a11y testing.
- Performance engineering: profiling, bundle splitting, SSR/CSR trade-offs, caching strategies, and Core Web Vitals optimization.
- API integration expertise with GraphQL and REST (schema-driven development, error handling, pagination, caching, and client state strategies).
- MUST: Proficiency using AI-assisted engineering tools (e.g., Claude Code, GitHub Copilot ) to accelerate implementation, refactoring, test creation, and debugging-while validating correctness and adhering to secure handling practices.
