Lead Software Engineer - UI - Typescript/React/Redux Toolkit (FX)

We have an opportunity to impact your career and provide an environment where you can push the limits of what’s possible.
 

As a Lead Software Engineer at JPMorgan Chase within the Commercial & Investment Bank’s Sales & Research Technology team, you will contribute to the creation, design, and delivery of market-leading, client- and sales-facing web applications for the J.P. Morgan Markets Execute platform. You will apply strong front-end engineering skills, modern development practices, and structured problem-solving to build secure, stable, and scalable UI solutions with meaningful business impact.
 

Job responsibilities

• Build and support client- and sales-facing UI capabilities of the Markets Execute platform and its related suite of applications.
• Develop and evolve front-end architecture blueprints, including component hierarchies and scalable implementation patterns (e.g., component composition, state management with Redux Toolkit, TypeScript best practices) to support maintainable, modular, and testable codebases across teams.
• Collaborate with Product Owner, UX, and QA to analyse requirements; participate in estimation, planning, and architecture/design sessions.
• Develop user interface features using modern JavaScript/TypeScript and React, following established engineering standards and leveraging the team’s existing component library.
• Influence application design and delivery practices through code reviews, technical discussions, and contributions to shared libraries/frameworks where appropriate.
• Mentor junior developers and contribute to improving delivery quality, predictability, and engineering best practices within the team.
• Learn continuously about financial markets through colleagues, business partners, training resources, and workshops.
• Optimize web applications for performance and responsiveness; contribute to secure, stable operational standards (e.g., reliability, resiliency, and production readiness).
• Use enterprise-authorized AI-assisted engineering practices to improve code quality and delivery outcomes (e.g., AI-assisted refactoring, test acceleration, troubleshooting), while applying clear validation standards (secure coding, peer review, automated testing).
• Apply 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.
• Apply reactive programming and ensure operational stability across environments with robust automated testing and CI/CD.
   

Required qualifications, capabilities, and skills

• Bachelor’s Degree in Computer Science or equivalent experience.
• Formal training or certification in software engineering concepts and 5+ years of applied experience on front-end experience with JavaScript, TypeScript, ReactJS, Redux Toolkit, RxJS, and modern UI frameworks.
• Hands-on experience in system design, application development, testing, reactive programming, and operational stability.
• 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.
• 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.
• Proven ability to independently solve design and functionality problems with minimal oversight.
• Experience building high-performance desktop/web applications and optimizing for speed and UX.
• Strong test-driven development practice using modern source control and continuous integration.
• Experience working in fast-paced, Agile environments within financial services.
• Proficiency with AI-powered development tools to streamline workflows, improve code quality, and enhance developer efficiency.
• Excellent communication and collaboration skills across cross-functional teams.
• Hands-on experience with UI automation testing tools is required (E2E and/or integration testing), and ability to run/maintain tests in CI/CD.
   

Preferred qualifications, capabilities, and skills

• Nice-to-have knowledge of Java, Kubernetes, and Spring.
• Familiarity with Investment Banking, FinTech, or financial markets.
