Sr. UI Developer

Role: Sr. UI Developer

Location: Tampa, FL

Job Specifications

We are looking for a Senior UI developer to build and maintain the AU client dashboard portal - a React 19 application within JPMC Payments.  You will own feature delivery end-to-end composing modular micro-frontends from our internal design systems, managing complex application state, and driving high engineering standards with modern AI tooling. Willingness to overlap with offshore hours is required.

Core Skills (must-have)

• React 19 - deep expertise with hooks, functional components, performance patterns and modern data flow
• Redux/state management - structuring predictable app state (Redux + React Context), selectors, and side-effect handling across a large portal
• Micro-frontends - hands on experience architecting and integrating micro-frontends, including single-spa (OSS) for orchestrating independently deployable apps, shared dependency management, cross-app routing and runtime composition
• App composition - building the portal from modular reusable pieces; shared component libraries (SALT Design system + Pepper) container/layout patterns, and integration with legacy adapters (e.g. the VAM UI adapter) into one cohesive shell
• AI Tooling - fluent with AI-assisted development (GitHub Copilot, Claude, agentic workflows) to accelerate delivery while keeping code review discipline
• High Standards - TDD/unit testing (Vitest + React Testing Library, 80+% coverage), ESLint/Prettier compliance, accessibility, and clean, maintainable code

Working with our stack

• Micro-frontend orchestration; single-spa, module composition, shared runtime dependencies
• Forms & Validation: react-hook-form + zod
• Data grids: AG Grid Enterprise (Salt theme)
• Build/Tooling: Vite, Node 24, multi-env config (dev/qa/uat/prod)
• API Integration: axios against backend services
• Deployment: Docker + Kubernetes / Cloud Foundry Pipelines (Jenkins)

Ways of Working

• Willing to work offshore hours with meaningful overlap for collaboration, reviews and pairing
• Comfortable in a regulated environment; secure coding, provenance-tracked AI contributions, through peer review before merge

Nice to have:

• Experience with SALT/Pepper frameworks
• Single-spa root-config and utility module patterns at scale
• Prior payments or financial services UI experience
