About The Position

Greenlight is seeking a Staff Android Systems Engineer to spearhead the development of Android-based products on custom hardware. This role involves end-to-end ownership of the application layer, close collaboration with the OS, working with hardware vendors, shaping AOSP integration, and establishing engineering standards for building, testing, and deploying on device. It's a hands-on, application-focused position for an individual with deep Android OS knowledge and the ability to mature a developing codebase for production. Technologies used include Kotlin, RxJava, MVI architecture, Retrofit, Bitrise, Espresso, and Android Jetpack.

Requirements

BS degree in Computer Science or equivalent.
8 to 12 years of software engineering experience, with significant depth in Android platform or systems engineering.
AOSP fluency, including navigating the source tree and working with OEM/vendor teams.
Deep understanding of Android's security model (sandboxing, system app privileges, IPC threat surface, APK behavior variations).
Hands-on experience with update mechanisms (application-level to system-level OTA).
Comfort with adb shell and system-level diagnostic tools/tracing.
Experience shipping products where WebView is the primary UI surface.
Track record of building or evolving Android CI/CD pipelines, with knowledge of signing key hygiene, artifact provenance, and device-in-the-loop testing.
Experience designing device telemetry and fleet health systems, especially in constrained environments.
Quality-first mindset and ability to champion best practices in testing, observability, and release confidence.
Strong communication skills to translate technical findings for non-technical stakeholders and lead across teams.
Genuine excitement about AI and applying it to engineering problems.

Responsibilities

Work on Android apps that leverage AOSP capabilities, navigate framework code, collaborate with ROM and vendor teams, and translate app layer needs to platform capabilities.
Add and enhance existing functionality in the Greenlight Android mobile app.
Design and expose system services, Binder/IPC interfaces, and AIDL-based APIs for secure inter-process communication.
Own the permissions, signing, and app identity model, understanding the 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 primary UI surface, managing the native/web boundary, JS bridges, performance, security, and hybrid debugging.
Build and maintain Android CI/CD pipelines, including device-in-the-loop testing, self-hosted runners, multi-module builds, and automated deploys to real hardware.
Design, implement, and extend device telemetry, health signaling, and heartbeat systems, considering battery, bandwidth, and privacy.
Harden pilot-quality software into production-grade systems by adding observability, addressing failure modes, and improving reliability.
Build field debugging infrastructure, including log pipelines, crash capture without Firebase, remote bug reports, and on-device diagnostics.
Serve as the technical bridge between platform architecture and product engineers' daily challenges.
Mentor and lead peers in a distributed, cross-geography 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.
