Senior Android Platform Engineer (AOSP)

Senior Android Platform Engineer (AOSP) - Remote, Latin America

Ruzora places senior engineers from Latin America with US startups. We are looking for a Senior Android Platform Engineer to work full-time with a US startup building an AI-first phone: their own Android-based OS that runs on Pixel hardware and operates existing apps on the user's behalf. This is system-level work, not app development.

What you will do:
- Build and maintain a custom Android OS on AOSP (Soong/Android.bp, device trees, Pixel builds)
- Change framework code and write system services in Java/Kotlin and C++, exposed over Binder/AIDL
- Build the automation layer that drives third-party apps (AccessibilityService, UI Automator-style input, notification listener)
- Own privileged and system apps, signature permissions and SELinux policy
- Ship A/B OTA updates with update_engine and safe rollback
- Keep an always-on agent fast and battery-efficient within Doze and
