What you'll do

• Architect a robust, battery-efficient SDK that runs silently in the background of third-party apps
• 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
• Ensure that data collection and processing are highly optimized to minimize CPU impact on the host application
• Handle the fragmentation of the Android ecosystem, ensuring our SDK works across Samsung, Xiaomi, Pixel, and other OEM ROMs
• This is a role for someone who enjoys reverse-engineering how the OS works and working on "hard" problems.

Who you are

• University degree in Computer science or equivalent knowledge required
• 5+ years of professional Android development experience.
• Expert proficiency in Kotlin and Java
• Strong understanding of the Linux OS. You know what /proc/net and /sys/class/net contain and how to parse them efficiently.
• Deep understanding of Android permissions, the Application Sandbox, and SELinux policies (and how to work within them)
• Mastery of WorkManager, Foreground Services, and limitations like Doze Mode and App Standby Buckets.
• Experience with LocationManager, GnssStatus, and handling location permissions in the background.
• Advanced English communication skills, German is a plus
