  • Implement and maintain gRPC services and clients (and JSON/REST-style APIs where applicable) that connect system components to higher-level layers (Electron/TypeScript UI, server-side services).
  • If you have Windows experience, contribute to Windows system components in modern C++ using the Windows Cloud Files API (CFAPI).
  • Develop and maintain unit tests (gtest) and integration tests (Python + pytest) to build and extend automated coverage.
  • Integrate with Finder for file badges, context menus, and other extensions using File Provider and PlugInKit.
  • Use tools like Xcode, LLDB, and Instruments to debug complex issues in production-like environments.
  • Contribute to build and CI/CD pipelines (e.g., Jenkins, Xcode build system, Swift Package Manager, shell scripting).
