LA Consultancy3 weeks agoUntil 19/9/2026
Job description
Job Requirements :
BE, BTech, or MCA candidates having 6+ years of experience with strong TypeScript/JavaScript, React 19, Lit 3, Vite, Webpack, and Node.js, where understanding the runtime is more important than framework-specific muscle memory.
Technical Expertise :
- React expertise: The platform shell and primary component library are React-first, so hooks, context, portals, concurrent features, and the React 19 event model should feel natural.
- Web Components and Custom Elements: Should understand Shadow DOM, custom element lifecycle, attribute/property bridging, and the challenges of embedding frameworks inside custom elements.
- Web platform fundamentals: CSS architecture (tokens, SCSS, Tailwind), accessibility (WCAG AA, aria patterns, keyboard navigation), browser APIs, and performance optimization.
- Backend comfort: Not required to be a backend specialist, but comfort reading and modifying Spring Boot services, understanding REST APIs, JWT auth flows, and database schemas makes you far more effective.
Additional Qualifications :
- Experience with micro-frontend architectures (Module Federation, Web Components as integration boundary, runtime composition).
- Experience building or maintaining shared component libraries consumed by multiple teams.
- Familiarity with enterprise concerns: RBAC, SSO integration (SiteMinder, ForgeRock, OIDC), and API gateways (Layer 7).
- Infrastructure awareness: Docker, ECS, CloudFront/S3, Terraform, and Jenkins pipelines.
- Accessibility expertise: axe, NVDA/VoiceOver testing, and ARIA authoring practices.
- Experience with Playwright for E2E or component testing.
- Background in financial services or regulated industries.
