This role
This is not a conventional Android app development role (building applications for the Play Store). We are seeking a specialized systems engineer focused on the heart of the operating system: AOSP (Android Open Source Project) and the TEE (Trusted Execution Environment).
In this role, you will bridge the gap between high-level Android features and low-level hardware integration, ensuring our proprietary security mechanisms—which protect our assets at the OS level—are robust, performant, and tamper-proof.
