Senior Lead Software Engineer - UI Developer, Equities Risk Management

JPMorgan Chase & Co.•Jersey City, NJ

About The Position

As a Senior Lead Software Engineer at JPMorganChase within the Equities Risk Management Team, you are an integral part of an agile team that works to enhance, build, and deliver trusted market-leading technology products in a secure, stable, and scalable way. Drive significant business impact through your capabilities and contributions, and apply deep technical expertise and problem-solving methodologies to tackle a diverse array of challenges that span multiple technologies and applications. Design and deliver high-performance React interfaces over large-scale real-time datasets, replacing an established fat client platform used by traders across global trading desks. Work directly with front-office traders to understand requirements, often inferring detailed specifications from existing tools and workflows rather than formal briefs, and iterating rapidly on feedback. Collaborate closely with the backend services team and external data platform vendors to integrate bleeding-edge data delivery technologies into the frontend stack.

Requirements

Formal training or certification on software engineering concepts and 5+ years applied experience
Hands-on practical experience delivering system design, application development, testing, and operational stability
Advanced proficiency in React and TypeScript with a track record of building production applications against high-performance, low-latency requirements
Strong experience with enterprise data grid frameworks (e.g. AG Grid) including virtualisation, server-side row models, and rendering optimisation over large datasets
Ability to tackle design and functionality problems independently with little to no oversight

Practical use of AI tooling (e.g. Copilot, Claude) in development workflows to accelerate delivery, reverse-engineer existing UX, or generate specifications from reference applications
