Software Engineer, DevOps, Android Developer

Job Title:
Software Engineer – Hardened Android Platform

This role focuses on building and owning a hardened, custom Android platform deployed across managed vehicle device fleets. You will take end-to-end responsibility for custom OS builds, over-the-air (OTA) delivery, kernel maintenance, device security, and fleet management infrastructure. As a founding platform engineer, you will define the architecture, establish technical standards, and provide leadership as the organization scales, working closely with a growing team of engineers in a high-impact, security-focused environment.

• Maintain and extend a custom Android Open Source Project (AOSP)-derived platform build, including device trees, vendor partitions, hardware abstraction layer (HAL) customizations, and system image signing.
• Design and operate reproducible build pipelines using CI/CD automation, ensuring secure management of release keys throughout the build and deployment lifecycle.
• Build an end-to-end OTA update system engineered for reliability in degraded or constrained environments, including phased rollout, rollback capabilities, and fault-tolerant installation processes.
• Build, patch, and maintain custom Linux kernel images for the target platform, including kernel module development, integration of upstream security patches, and ongoing performance and stability improvements.
• Own the secure boot chain for the platform, including Android Verified Boot (AVB) key infrastructure, boot loader security, SELinux policy authoring, and code signing with robust key lifecycle management.
• Implement encryption, remote wipe, tamper detection, and rollback protection mechanisms appropriate for high-assurance and security-sensitive environments.
• Evaluate and integrate cryptographic modules that align with U.S. government cybersecurity frameworks and standards, ensuring compliance and strong security posture.
• Architect and implement a comprehensive device management strategy, including enrollment, provisioning, policy enforcement, health monitoring, and compliance reporting across large-scale fleets.
• Collaborate with reverse engineers and other platform and security engineers to enhance system resilience, harden the platform, and respond to emerging threats.
• Contribute to platform architecture decisions, documentation, and best practices that support long-term scalability and maintainability of the fleet management infrastructure.

• Bachelor’s degree in an engineering discipline or a closely related technical field.
• Approximately 7 or more years of software engineering experience focused on low-level platform development, ideally on an Android-based platform.
• Strong proficiency in C and C++ for systems and kernel-level development.
• Proficiency in Python and Shell scripting for automation, tooling, and build pipelines.
• Working knowledge of Java and Kotlin for Android framework-level modifications and system integration work.
• Hands‑on Linux kernel development experience, including building from source, kernel module development, device tree configuration, and debugging kernel-level issues.
• Experience working with Linux and Android environments in production or operational settings.
• Experience managing device fleets at scale in real‑world operational environments, including monitoring, updates, and policy enforcement.
• Eligibility to obtain a U.S. Secret Clearance
• Ability to design and maintain CI/CD-based build pipelines with secure key management and reproducible builds.

• Experience with Android system-level development, focusing on platform and OS internals rather than application development.
• Experience building, modifying, and flashing custom Android system images from…
