Senior Android Platform Engineer​/Architect

Job Description

Our Client is building a hardened, custom Android platform for deployment across managed device fleets.

We are hiring an engineer/architect who can own this domain end to end: custom OS builds, OTA delivery, kernel maintenance, device security, and fleet management infrastructure.

This is a founding platform engineering role. You will define the architecture, set the standards, and lead as we scale. You will work alongside a growing engineering organization focused on core product lines.

• Maintain and extend a custom AOSP-derived platform build, including device trees, vendor partitions, HAL customizations, and system image signing
• Design and operate reproducible build pipelines with CI/CD automation and secure release key management
• Build an end-to-end OTA update system engineered for reliability in degraded environments - including phased rollout, rollback, and fault‑tolerant installation
• Build, patch, and maintain custom Linux kernel images for the target platform, including kernel module development and upstream security patch integration
• Own the secure boot chain: AVB key infrastructure, boot loader security, SELinux policy authoring, and code signing with proper key lifecycle management
• Implement encryption, remote wipe, tamper detection, and rollback protection appropriate for high‑assurance environments
• Evaluate and integrate cryptographic modules aligned with U.S. government cybersecurity frameworks and standards
• Architect device management strategy - enrollment, provisioning, policy enforcement, health monitoring, and compliance reporting across the fleet

• 7+ years software engineering experience, with 4+ years focused on Android platform and system‑level development (not application development)
• Experience building, modifying, and flashing custom Android system images from AOSP or comparable open‑source base
• Hands‑on experience with Android Verified Boot, boot loader security, and the secure boot chain
• Linux kernel development: building from source, module development, device tree, debugging
• Familiarity with Android OTA internals: , A/B partitioning, payload generation, boot control HAL
• Strong security engineering fundamentals: PKI, code signing, chain of trust, FDE/FBE, key management
• Proficiency in C/C++, Python, and Shell; working knowledge of Java/Kotlin for framework‑level modifications
• Experience with FIPS 140-2/3 cryptographic module integration
• Familiarity with U.S. government and regulated environment security frameworks (NIST 800-53 or equivalent)
• Experience managing device fleets at scale in operational environments
• Experience with Android Enterprise device owner and fully managed device APIs
• Contributions to AOSP or open‑source Android platform projects
• Experience designing update and delivery systems for intermittent or degraded connectivity
• HSM‑backed signing infrastructure experience
