About the Role

We’re building Sayso, a Windows-based (Electron) application, and are looking for a specialist to help us implement reliable system-level audio capture.

Our core app and backend are already in place. The key missing piece is capturing both microphone input and system audio simultaneously on Windows with high reliability and performance.

What You’ll Do

• Implement system-level audio capture for Windows
• Capture and sync:
  • Microphone input
  • System/desktop audio (loopback)
• Work with low-level Windows audio APIs to ensure:
  • Stability
  • Low latency
  • High audio quality
• Integrate the solution with an Electron-based app
• Troubleshoot edge cases across different Windows devices and drivers

Requirements

• Strong experience with Windows audio systems
• Hands-on experience with:
  • WASAPI (especially loopback capture)
  • C / C++ for low-level audio handling
• Understanding of:
  • Audio drivers
  • Buffering, latency, and synchronization
• Experience integrating native modules with Electron / Node.js is a strong plus

Nice to Have

• Experience with audio processing pipelines
• Prior work on recording, streaming, or conferencing apps
• Familiarity with cross-device compatibility issues on Windows
