Staff Android Systems Engineer

Role Overview

Greenlight is seeking a Staff Android Systems Engineer to lead development of Android-based products running on custom hardware. You will own the application layer end-to-end while working closely with the Android OS, collaborating with hardware vendors, and shaping AOSP integration.

Responsibilities

• Develop Android apps that leverage AOSP-level capabilities, navigating framework code as needed.
• Collaborate directly with ROM and vendor teams, translating application-layer needs to platform capabilities.
• Add and enhance functionality in the Greenlight Android mobile app.
• Design and expose system services, Binder/IPC interfaces, and AIDL-based APIs for secure, reliable inter-process communication.
• Own the permissions, signing, and app identity model, including differences between standard and privileged/system apps.
• Drive PackageManager and app installation strategy, including silent installs, self-updating apps, rollback, and verification.
• Champion WebView as a first-class surface, owning native/web boundary concerns (JS bridges, performance, security, hybrid debugging).
• Build and maintain Android CI/CD pipelines, including device-in-the-loop testing, self-hosted runners, multi-module builds, multiple signing configurations, and automated deploys to real hardware.
• Design and extend device telemetry, health signaling, and heartbeat systems with battery/bandwidth/privacy tradeoffs.
• Increase reliability by adding observability, addressing long-tail failures, and improving production readiness.
• Build field debugging infrastructure: log pipelines, crash capture without Firebase, remote bug reports, and on-device diagnostics.
• Serve as the technical bridge between platform architecture and product engineering pain points; mentor peers in a distributed environment.
• Translate technical findings into business-relevant insights for engineering, QA, and leadership.
• Apply AI tooling to engineering problems in development, diagnostics, and platform automation.

Requirements

• BS in Computer Science (or equivalent).
• 8–12 years of software engineering experience, with substantial depth in Android platform/systems engineering.
• AOSP fluency (navigated source tree; worked with OEM/vendor teams).
• Deep understanding of Android security model, including sandboxing, system app privileges, and privileged IPC threat surface.
• Hands-on experience with update mechanisms from application-level to system-level.
