We have an exciting and rewarding opportunity for you to take your software engineering career to the next level.

As a Software Engineer III at JPMorganChase within the Employee platform, you serve as a seasoned member of an agile team to design and deliver trusted market-leading technology products in a secure, stable, and scalable way. You are responsible for carrying out critical technology solutions across multiple technical areas within various business functions in support of the firm's business objectives.

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).

• Leverages enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables (e.g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, automated testing, and secure coding standards; contributes learnings and reusable patterns to improve broader team effectiveness.

• Applies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation.

Required qualifications, capabilities, and skills

• 4+ years of professional software engineering experience with strong front-end focus; experience leading projects and mentoring engineers.

• Expert-level React (hooks, component composition, context, rendering behavior, concurrency patterns where applicable).Strong TypeScript (types as design, generics, strictness) and modern JavaScript fundamentals.

• Deep experience with front-end tooling (Vite/Webpack, Babel/SWC, npm/pnpm/yarn, monorepos) and build/release pipelines.

• Strong CSS skills (responsive design, CSS architecture, theming, scalable styling).

• Advanced testing practices (Jest/Vitest, React Testing Library, Playwright/Cypress) with ownership of test strategy.

• Accessibility expertise (WCAG/ARIA, keyboard navigation, screen readers, automated and manual testing).

• Performance engineering and API integration (profiling, bundle splitting, SSR/CSR trade-offs, caching, Core Web Vitals; GraphQL/REST, error handling, pagination, client state).

• Security and observability awareness (XSS/CSRF prevention, dependency hygiene, secure auth/session patterns, client-side logging/metrics, debugging production issues) plus MUST: proficiency with AI-assisted engineering tools (e.g., Copilot, Claude) with validation and secure practices.

• Hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment (e.g., for coding, test creation, troubleshooting, or documentation) with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security.

• Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations; ability to guide peers on safe and effective usage within team practices.

Preferred qualifications, capabilities, and skills

• 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).
