Job Description

  • 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.

  • 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.

Preferred qualifications

  • Experience leveraging a design system (Storybook, tokens).
  • Experience with micro-frontend patterns and module federation (where relevant).
  • Experience with visualization and rich UI: D3, Canvas/WebGL, advanced tables/grids, animation libraries.
  • Familiarity with authentication integrations (OIDC/OAuth2) and enterprise SSO constraints.
  • Proven track record modernizing legacy front ends and improving developer experience (D
