Principal Software Engineer - React, UI

Your next role should amplify your impact and accelerate your growth. Join a collaborative, hands‑on team building UI architecture and reusable component platforms that power secure, intuitive Trade Finance experiences at scale. As a Principal Software Engineer at JPMorganChase within the Trade & Working Capital, you will set the technical direction for frontend architecture and be hands-on building reusable React/TypeScript components and patterns adopted across multiple squads. You’ll partner across Product, Design, and Engineering to deliver consistent UX, high-performance UIs, and reliable integrations with Java-based services. You’ll work closely with product, design, and backend architecture. Turning complex requirements into simple, compliant front-end systems that hold up in regulated environments. We value practical leadership, clear communication, and accountability for outcomes—while staying close to code and production.

Own frontend architecture for customer-facing applications, including application structure, routing, state management, module boundaries, and integration patterns to enable scale, resiliency, and rapid delivery. Design, build, and maintain a reusable component platform/design system (React + TypeScript): core UI primitives, complex workflow components, accessibility standards, theming, documentation, and versioned release strategy. Stay hands-on in code: build high-impact components, reference implementations, and templates; drive adoption through pull requests, pairing, and technical reviews. Define and evolve shared UI patterns (forms, validation, tables/grids, document upload, approvals, error handling, notifications, entitlements-based rendering) to ensure consistency across customer journeys. Partner with backend teams to shape API contracts optimized for UI (latency expectations, pagination, error semantics, idempotency, versioning) and drive UI-friendly patterns (BFF where appropriate). Establish frontend performance engineering practices: bundle strategy, rendering efficiency, caching, and Core Web Vitals; ensure high performance under real-world workloads. Implement frontend observability and operability: client-side logging/metrics, correlation IDs, trace linkage, actionable dashboards, and runbooks for production support. Lead secure-by-design UI engineering: authN/authZ flows, secure session handling, PII masking, XSS/CSRF protections, dependency governance, and compliance guardrails. Coach engineers and raise standards in UI architecture, component quality, testing, and documentation, ensuring reusable assets are reliable and discoverable. Own delivery outcomes across multiple squads: roadmap alignment for the UI platform, release readiness, dependency management, and risk mitigation/escalation. Lead incident response and root-cause analysis for customer-facing applications; drive corrective/preventive actions that improve stability and user experience. 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 at scale. Apply GenAI/LLMs to enhance UI and operational workflows (e.g., guided task completion, intelligent assistance, search/summarization) with appropriate controls and governance. Architects and governs agentic AI-enabled engineering workflows (using enterprise-authorized tools within the work environment) to improve delivery speed, code quality, and operational outcomes at scale (e.g., AI-driven PR review assistance, test generation/maintenance, release readiness checks, incident triage and root-cause acceleration), while defining guardrails for validation, security, resiliency, and reuse across teams. Required qualifications, capabilities, and skills Formal training or certification on software engineering concepts and 10+ years of applied experience. In addition, 5+ years of experience
