• 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, bootloader 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 environments.
• Evaluate and integrate cryptographic modules that align with U.S. government cybersecurity frameworks and standards.
• Architect and implement a comprehensive device management strategy across large-scale fleets.
• Collaborate with reverse engineers and platform/security engineers to enhance resilience and respond to threats.
