  • Implement efficient methods to read and parse technical data from the Linux system (e.g., /proc, /sys, and legacy system files) to extract signal and network stats
  • Constantly research changes in new Android OS versions to identify which system files remain accessible to non-root applications and devise fallbacks when access is revoked

  • Experience with LocationManager, GnssStatus, and handling location permissions in the background.
  • Advanced English communication skills, German is a plus
