Job responsibilities

Lead development of complex, user-facing web applications using React + TypeScript, owning the front-end architecture and delivery approach.
Develop microservices / API contracts (GraphQL/REST) using Java and Spring technologies and front-end friendly design patterns (pagination, filtering, error models).
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 JPMC’s EXDS UI foundations: design system / component library, theming, responsive layouts, and cross-browser compatibility.
Drive performance and quality: Core Web Vitals, bundle optimization, rendering strategies, caching, and runtime observability.
Implement advanced UI capabilities such as rich data visualization, real-time updates, offline-friendly patterns, and robust form/workflow experiences.
Ensure secure client-side patterns: safe auth flows, token handling guidance, secure storage, and protection against common web vulnerabilities.

Required qualifications, capabilities, and skills

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.
