  • Packaging the core library and defining a versioned public API (DLL/SO).
  • Ensuring system resilience with failover logic, error handling, and health checks.
  • Executing comprehensive testing (unit, integration, GUI, performance).
  • Developing and packaging the executable wrapper for Windows/Linux, including UI shell.

Requirements

  • Experience as a C++/Qt Engineer for 4+ years.
  • Full-stack desktop development expertise.
  • Focus on security, performance, and efficient resource usage.
  • Experience with cross-platform application packaging and distribution.
