In this role, you will bridge the gap between low-level hardware security, kernel hardening, and secure user-space application containment. You will not only design cryptographic defense mechanisms but will also automate security pipelines in CI/CD and partner directly with manufacturing teams to ensure devices are provisioned securely and reliably at scale without production risks.</p> <p><strong>Responsibilities&nbsp;</strong><br>&nbsp; &nbsp; • Platform Hardening &amp; Architecture: Design and implement the Hardware Root of Trust and Secure Boot architecture from the first-stage bootloader through the Linux kernel.<br>&nbsp; &nbsp; • Storage &amp; Integrity Management: Implement dm-verity for cryptographically verified read-only root filesystems and secure data encryption at rest.<br>&nbsp; &nbsp; • Trusted Execution Environments: Develop, integrate, and maintain a TEE (e.g., OP-TEE) and author Secure/Trusted Applications (TAs).<br>&nbsp; &nbsp; • Application Sandboxing: Enforce strict user-space isolation and sandboxing strategies using SELinux, AppArmor, cgroups, namespaces, and seccomp filters to protect core systems from untrusted applications.<br>&nbsp; &nbsp; • DevSecOps Automation: Build automated cryptographic signing pipelines within CI/CD infrastructure (e.g., GitLab CI, GitHub Actions) to securely sign bootloaders, kernels, and OTA payloads using HSMs or secure key vaults.<br>&nbsp; &nbsp; • Production Provisioning Support: Collaborate with manufacturing teams to write robust scripts and tools for burning permanent hardware configuration fuses (eFuses / OTP memory) securely, designing end
