What you’ll need

  • Recent, hands on experience building complex production applications with React and TypeScript.

  • Strong knowledge of frontend architecture, state management, browser APIs and performance.
  • Experience with complex interfaces such as chat, collaboration, document editing, calendars, workspaces or comparable productivity products.
