Lead Front-End Engineer (React/Web) Engineer

Hi,

Lead Front-End Engineer (React/Web) Engineer

Role summary
Lead the design and development of modern, high-performance web experiences
using React and the broader front-end ecosystem. This role is front-end focused,
partnering closely with Product, UX, and backend/platform teams to deliver cutting-
edge UI capabilities and set engineering standards.

Job responsibilities
Lead development of complex, user-facing web applications using React +
TypeScript, owning the front-end architecture and delivery approach.
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.
Collaborate with backend teams on API contracts (GraphQL/REST) and
advocate for front-end friendly patterns (pagination, filtering, error models).

Required qualifications, capabilities, and skills
10+ 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.
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.

Preferred qualifications
Experience with SSR/meta frameworks: Next.js / Remix and SEO
considerations.
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 (DX).
