Senior UI Engineer

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.
Major Responsibilities
Build and maintain production features in the 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, Git Hub 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
Qualifications   Qualifications
Required
5–7 years of frontend engineering experience in production environments at meaningful scale
React proficiency — hooks, context, state management libraries (Redux, Zustand, Jotai, or equivalent); comfortable owning a React codebase from first commit to production
Type Script — strong typing discipline across both Angular and React contexts; you think in types, not around them
Testing discipline — you write unit tests, component tests, and integration tests as part of the work, not after; you know the difference between a test that proves correctness and one that just passes
HTML, CSS, SCSS fundamentals — semantic markup, responsive layouts, accessible design (WCAG) by default, not as an afterthought
Git workflow fluency — feature branching, pull request workflows, code review, CI/CD integration; you leave the branch in a better state than you found it
A track record of shipping — you can point to features running in production, not just repos on Git Hub; you know what it takes to get from working locally to working for users
Nice to Have
Angular 17+ — standalone components, RxJS, Angular Material, router guards — or genuine eagerness to learn it fast; we care more about the quality of your Angular questions than whether you already know the answers
Azure AD / MSAL — frontend authentication patterns in Azure AD environments, token handling, and silent refresh
Application Insights — frontend telemetry, custom event tracking, and dependency correlation; knowing what to instrument and why
