  • 14+ 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.
  • Strong Java and Java Spring skills to develop microservices / API contracts (GraphQL/REST) using Java and Spring technologies and front-end friendly design patterns (pagination, filtering, error models).
  • 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).
  • Security awareness for web apps: XSS/CSRF prevention, dependency hygiene, secure auth/session patterns (OIDC awareness a plus).
  • Observability for the front end: client-side logging/metrics, error reporting, and debugging production issues.
  • 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.

Thanks, IT First Source
