About The Position

We're looking for a Senior UI Engineer who wants to own the frontend end-to-end. You'll be the primary engineer on an Angular 17 application in production today, and the architect of React applications being scoped for tomorrow. This is a hands-on role — you write code every day, you ship features, and you hold the quality bar without needing to be asked. Key Objectives Own the frontend. You are accountable for the Angular codebase today and the React applications coming next. You make the architectural calls, you unblock the team, and you care about what ships. Be hands-on. No abstraction from delivery. You write production code, review PRs, and debug issues in the wild. Senior here means depth of craft, not distance from it. Deliver with urgency. Working software over completed designs. You have a bias for shipping and a tolerance for iteration. You know how to make pragmatic tradeoffs without cutting the wrong corners. Grow deliberately. The stack will evolve. The AI tooling will evolve. You embrace that — adopting agentic coding tools, learning new frameworks, and pushing the team forward technically.

Responsibilities

Build and maintain production features in the Pathfinder Angular 17 application — standalone components, reactive forms, RxJS, Angular Material, and MSAL/Azure AD authentication
Architect and deliver React applications as new products are scoped, from initial setup through to production deployment
Integrate with FastAPI and NestJS backends — REST APIs, server-sent event (SSE) streaming for AI response delivery, and file upload pipelines
Implement performant, accessible, and responsive UIs that surface AI outputs: streaming chat interfaces, RAG responses, document processing status, and structured data visualization
Write and maintain unit, component, and integration tests (Karma/Jasmine today; Jest or Vitest in React contexts) — without being asked
Participate actively in code reviews; articulate the reasoning behind your feedback and hold the team to a high standard
Instrument UIs with Azure Application Insights; own frontend observability, error tracking, and performance monitoring
Leverage agentic coding tools — Claude Code, GitHub Copilot, and their successors — as a genuine productivity multiplier, not a novelty
Collaborate closely with backend engineers, AI/ML platform engineers, designers, and product managers to translate complex AI capabilities into intuitive, trustworthy user experiences
Contribute to frontend architecture decisions: state management patterns, component design systems, CI/CD pipeline configuration, and dependency management
