  • Experience with process management services on Android.
  • Experience with Android Software Development Kit (SDK).
  • Experience in cross-compiling Linux/C/C++ code and libraries to mobile devices via Android Native Development Kit (NDK).
  • Experience using network traffic capture and monitoring tools (Wireshark, PCAP).
  • Test writing in Espresso, Robotum, JUnit, and/or comparable environment.
  • Good interpersonal and open-source collaboration skills.

Desired qualifications:

  • Experience with Rust and Go on Android.
  • Automated testing and continuous integration using cloud based services.
