Software Engineer

Senior Android Platform Engineer

About the Role

We are building a hardened, custom Android platform designed for deployment across large-scale, managed device fleets operating in high-assurance environments.

We're looking for experienced engineers who can take full ownership of this domain-from custom OS builds and kernel development to device security and fleet management infrastructure. This is a foundational platform engineering role where you will define architecture, establish engineering standards, and play a key leadership role as the platform and team scale.

You'll collaborate closely with a growing engineering organization to deliver a secure, reliable, and highly maintainable platform.

Key Responsibilities

• Platform Development

• Maintain and extend a custom AOSP-based platform, including device trees, vendor partitions, HAL customizations, and system image signing

• Build, modify, and flash Android system images from source

• Build & Release Engineering

• Design and operate reproducible build systems with CI/CD automation

• Manage secure release processes, including signing infrastructure and key lifecycle management

• OTA & Update Systems

• Architect and implement a robust OTA update pipeline

• Support phased rollouts, rollback mechanisms, and fault-tolerant installations-especially for constrained or degraded environments

• Kernel Engineering

• Build, customize, and maintain Linux kernel images

• Develop kernel modules and integrate upstream security patches

• Debug system-level and kernel-level issues

• Security & Trust Infrastructure

• Own the secure boot chain, including AVB key management, bootloader security, and SELinux policy development

• Implement strong device protections such as encryption, rollback protection, tamper detection, and remote wipe

• Evaluate and integrate cryptographic modules aligned with U.S. government cybersecurity standards

• Fleet & Device Management

• Design and implement device lifecycle management systems, including enrollment, provisioning, policy enforcement, and compliance reporting

• Build infrastructure for fleet health monitoring and operational visibility

Required Qualifications

• 7+ years of software engineering experience, including:

• 4+ years in Android platform or system-level development (not application development)

• Strong experience working with AOSP or similar open-source platforms

• Hands-on experience with:

• Android Verified Boot (AVB) and secure boot chains

• Bootloader security and device integrity enforcement

• Android OTA systems (e.g., update_engine, A/B partitioning, payload generation)

• Deep Linux kernel expertise:

• Building from source, module development, device tree configuration, and debugging

• Security engineering fundamentals:

• PKI, code signing, chain of trust, encryption (FDE/FBE), and secure key management

• Strong programming skills in:

• C/C++, Python, and Shell scripting

• Working knowledge of Java/Kotlin for Android framework-level development

Core Skills

• Linux Systems Engineering
• Android Platform Development
• System-Level Software Engineering

Why This Role

This is a unique opportunity to join at the ground level and define the technical foundation of a mission-critical Android platform. You'll have the autonomy to shape architecture decisions, influence long-term strategy, and work on complex challenges at the intersection of operating systems, security, and large-scale device management.
