• Experience designing cross-platform systems (MacOS + Windows) with consistent behavior.
• Hands-on work with real-time tracking, event streams, or activity monitoring systems.
• Familiarity with OS-level APIs for capturing user/system interactions.
• Deep understanding of performance optimization in desktop environments.
• Strong debugging skills and ability to reason about edge cases in distributed/offline systems.

Preferred

• Experience building productivity, monitoring, or telemetry-driven applications.
• Knowledge of native OS integrations (permissions, background processes, system hooks).
• Understanding of security and privacy considerations in user activity tracking.
• Familiarity with auto-update systems and release management in Electron.
