Lead Ui Engineer — React, Typescript, Design-led, Ai-driven Interfaces

JPMorgan Chase JPMorgan Chase · Banking · Jersey City, NJ +1 · Commercial & Investment Bank

This role is for a Lead UI Engineer focused on building AI-enhanced user interfaces for internal enterprise applications. The primary focus is on front-end development using React and TypeScript, with a strong emphasis on integrating and leading the adoption of AI-assisted engineering practices and responsible AI use within the development lifecycle. While the role works with AI-driven interfaces and AI tools, it does not directly build AI models or agents.

What you'd actually do

  1. Lead the development of sophisticated AI-enhanced user interfaces for large-scale internal tools.
  2. Translate designer vision into polished, pixel-perfect front-end experiences, demonstrating a keen eye for detail, aesthetics, and high-quality UI execution.
  3. Collaborate cross-functionally with product, design, and backend engineering teams to deliver seamless, forward-thinking solutions.
  4. Own the codebase by writing clean, efficient, and reusable React code, and uphold high standards through rigorous code reviews.
  5. Drive quality through thorough testing, proactive troubleshooting, and continuous optimization of performance and reliability.

Skills

Required

  • Formal training or certification on software engineering concepts and 7+ years applied experience
  • Demonstrate deep expertise in JavaScript/TypeScript and advanced proficiency in React, with a track record of building and maintaining complex applications.
  • Possess a strong background in modern web development, including responsive design, performance optimization, REST APIs, and asynchronous data flows.
  • Write clean, testable code with meaningful unit and integration test coverage.
  • Apply Web Content Accessibility Guidelines (WCAG) accessibility standards and best practices to ensure inclusive user experiences.
  • Work effectively in agile, distributed teams, contributing to sprint planning, code reviews, and iterative delivery.
  • Communicate clearly with stakeholders at all levels, translating technical complexity into accessible language.
  • Demonstrated experience leading effective use of approved AI-assisted software development tools (e.g., for coding, code review, test acceleration, troubleshooting) with the ability to set team expectations for validating AI outputs for correctness, performance, and security.
  • Strong understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations; experience coaching engineers on safe, compliant adoption within delivery practices

Nice to have

  • Hands-on experience with design systems, component libraries, and delivering consistent UI/UX at scale.
  • Experience with state management libraries such as Redux, Zustand, or React Query.
  • Familiarity with AI/ML APIs or integrating LLM-based features into production applications.
  • Comfort working with design tools such as Figma for design collaboration and handoff.
  • Design, implement, and manage CI/CD pipelines to automate software build, test, and deployment processes.
