Android Developer Full-time

The Tor Project is looking for an Android OS Developer!

As an Android OS Developer, your job will be to work closely with other members of the development team to build and release a Tor Browser for Android with functionality and build processes in parity with the desktop browser. This is a full-time position.

Being a Tor developer includes triaging, diagnosing, and fixing bugs; looking for and resolving mobile privacy issues; responding on short notice to urgent security issues; and working collaboratively with coworkers and volunteers to implement new features and mobile behavior changes. We also need help making our code more maintainable, testable, and mergeable by upstream. The person in this position will review other people’s code, designs, and academic research papers to make suggestions for improvement.

This position will also focus on the following tasks/projects:

• Design TorService API/integration with Fennec Mobile Android Java code.
• Automate a continuous build process.
• Make Tor Browser for Android a standalone application by porting the Orbot connection to Tor.
• Create a Gradle-dependent standalone Tor Service Library for Android.
• Coordinate uplifting of mobile patches.

Required Qualifications:

• 5+ years experience with developing and testing Java/JNI, Android APIs, and library dependencies.
• 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 reproducible builds on desktop or mobile.
• User interface and usability skills (nice, but not essential for this role).
• Shipped public applications with NDK features.
• Experience with Rust and Go on Android.
• Automated testing and continuous integration using cloud based services.
• Network knowledge and/or experience; experience investigating leaks.

Other notes:

• Academic degrees are great, but not required if you have the right experience!
