THE OPPORTUNITY

Are you ready to dive deep into the Android Open Source Project (AOSP), build system services, and work directly with the kernel interface?
Flock is looking for a system-level engineer to own and develop critical device functionality. No UI components here! We run on headless, custom Android devices. Our Engineering team is made up of driven people who are responsible for all the code running on the variety of devices Flock deploys in the real world. They enable the entire experience by providing Android Applications, Services, and other key components that reliably capture, process, and upload data for years at a time without needing human interaction to keep them running.

HOW YOU'LL MAKE AN IMPACT:

- Take ownership of a feature or module and deliver it with high quality.

- Be responsible for a certain amount of QA and quality of your work.

- Write clean, testable, and automatable code.

- Document your work and test cases, and collaborate with program, product, QA, and other engineering teams.

- Estimate work with reasonable accuracy and communicate adjustments as needed.

- Assist in resolving issues reported in the field.

- Identify and champion new features that will benefit Flock.

- Identify and improve upon deficiencies in our products and processes.

- Give tech talks.
