We are looking for a Senior React Engineer with deep expertise in modern React and TypeScript, strong API integration experience, and practical, daily use of AI coding tools.
This role involves leading the frontend modernization effort, collaborating closely with .NET backend engineers, and ensuring the new platform is scalable, maintainable, and production-ready.
Responsibilities
Frontend Development

- Critically review AI-generated code for correctness, performance, and accessibility
- Structure tasks to maximize AI tool effectiveness
API Integration
- Integrate with .NET RESTful APIs
- Handle data fetching, caching, optimistic updates, and error states
- Collaborate on contract-first API design
System Modernization & Migration

Testing & Quality
- Write component and integration tests (React Testing Library, Vitest/Jest)
- Leverage AI to accelerate coverage
- Ensure automated tests validate functional equivalence
Delivery & Data Migration
- Deliver features in staged increments with checkpoints
- Support migration of existing system data and additional flat-file imports
UI/UX & Styling
- Build responsive, consistent interfaces using modern styling approaches
- Translate design specs or legacy UI screenshots into scalable React components
Knowledge Sharing
- Help teammates adopt AI-assisted frontend practices
- Share effective prompting techniques and internal best practices
Requirements
- Deep expertise in modern React (functional components, hooks, custom hooks, lifecycle understanding)
- Strong decision-making around state management (Context API, Zustand, Redux Toolkit, etc.)

Build Tooling & DX
- Comfortable with Vite (preferred) or Webpack
- Experience with ESLint, Prettier, and monorepo setups if needed
- Ability to maintain fast, reliable developer workflows
Nice to Have
- Experience analyzing legacy PHP-rendered frontend (server-side templates, jQuery, vanilla JS) for migration
- Experience building design systems or shared component libraries (Storybook)
- Authentication & authorization UI (OAuth/OIDC, token handling, role-based UI)
