You will partner with UX/Product, translate designs into polished interfaces, and establish front-end standards while leveraging advanced tooling

Qualifications

• 14+ years professional software engineering experience with significant depth in front-end web development.
• Expert-level React proficiency (hooks, context, rendering behavior).
• Strong TypeScript skills with modern JavaScript fundamentals.
• Strong Java and Spring skills to develop microservices / API contracts.
• Deep experience with modern front-end tooling (Vite/Webpack, Babel/SWC).
• Strong CSS skills for responsive design and theming.
• Advanced testing practices (Jest/Vitest, RTL, Playwright/Cypress).
• Security awareness for web apps (XSS/CSRF, secure patterns).
• Observability for the frontend (logging/metrics, debugging production).
• MUST: Proficiency with AI-assisted engineering tools to accelerate implementation.

Responsibilities

• Lead development of complex, user-facing web applications using React + TypeScript and own front-end architecture.
• Develop microservices / API contracts (GraphQL/REST) with Java and Spring.
• Collaborate with UX/Product to translate designs into polished experiences, considering feasibility and performance.
• Establish and evolve front-end standards: components, state management, routing, testing.
• Build using EXDS UI foundations: design system, theming, responsive layouts, cross-browser compatibility.
• Drive performance and quality: Core Web Vitals, bundle optimization, caching, observability.
• Implement rich UI capabilities: data visualization, real-time updates, offline patterns, robust forms.
• Ensure secure client-side patterns: safe auth flows, token handling, secure storage.
