Job description

  • Role: UI Engineer (Embedded Domain)
  • Type: 6-Month Contract (Inside IR35)
  • Location: London, UK (Remote)

Role Overview:
Join the team building the C2C Finance Companion, an AI suite assisting finance teams with contract booking, billing, and collections. Embedded in a dedicated squad, you will build user-facing screens in a shared React shell and migrate legacy front ends without downtime.


Key Responsibilities
  • Build production-grade domain screens and AI chat interfaces (streaming responses, confirmation flows, error handling).
  • Migrate existing standalone front ends into the centralized shell and decommission legacy versions.
  • Consume and upstream shared UI components using design tokens.
  • Partner with Go engineers to integrate GraphQL queries and real-time subscriptions.
  • Ensure UI quality through automated testing, WCAG 2.1 AA accessibility, and web vitals optimization.

Requirements
  • 3-5+ years building production apps with React and TypeScript.
  • Experience with Tailwind CSS, headless UI libraries (Radix UI or shadcn/ui), and Apollo Client (GraphQL).
  • Modern testing and build tooling: Vitest, Testing Library, Playwright, and Vite.
  • Experience with enterprise browser auth via Microsoft Entra ID (MSAL).

Nice to Have
  • Front-end consolidation or micro-frontend migrations.
  • AI/conversational UI design.
  • Data-dense dashboards (tables, queues, approval flows).
  • Finance, ERP, or order-to-cash domain exposure.
