  • Strong eye for design detail and UX, with the ability to translate Figma or design specs into production code
  • Proficient with TypeScript, modern JS tooling (Webpack, Vite, etc.), and REST/GraphQL API integration

Desired Skills & Experience

  • Experience working on AI-powered products or interfaces that integrate ML outputs (e.g., assistants, chat UIs)
  • Familiarity with real-time messaging platforms, collaborative tools, or rich text editors
  • Exposure to data visualization libraries (e.g., D3, Recharts, Visx) and performance optimization techniques
  • Understanding of accessibility, cross-browser compatibility, and responsive design principles
  • Comfortable collaborating across backend, ML, and product teams in a fast-moving startup environment

What You Will Be Doing

  • 10% UI/UX Planning & Architecture
  • 10% Cross-functional Collaboration (with Design, Product, Backend, ML)
