About the role

  • Architect & Implement: Lead the development of complex React applications using modern patterns (Hooks, Context, Composition).
  • Design System Leadership: Build, maintain, and document reusable component libraries to ensure visual and functional consistency across our entire ecosystem, MUI experience preferred.
  • Performance & Best Practices: Optimize frontend performance, ensure accessibility compliance, and enforce clean code standards through rigorous peer reviews.
  • Collaborative Design: Partner closely with Product Designers to translate Figma mocks into high-fidelity, responsive layouts, providing technical feedback on UI/UX feasibility.
  • Full-Stack Awareness: Consume and occasionally contribute to API design (Node.js/Python) to ensure seamless data flow between the frontend and backend.
  • Data-Driven Iteration: Use monitoring and analytics (logs, usage metrics) to identify friction points in the user journey and implement UI improvements.
  • AI-Augmented Workflow: Champion the use of AI coding assistants (e.g., Cursor, Claude Code, GitHub Copilot) to accelerate feature delivery, refactor legacy code, and maintain high test coverage.

Requirements

  • 5+ Years of Experience: A proven track record of shipping production-grade web applications.
  • AI Proficiency: Extreme comfort using AI agents to write, debug, and document code. You should be able to demonstrate how you use prompts and context to solve complex architectural problems.

  • Engineering Excellence: Experience with TypeScript, modern testing libraries, and frontend build tools.
  • Communication: Ability to bridge the gap between design and backend engineering, explaining complex frontend constraints to non-technical stakeholders.
