Job summary

GlobalLogic is looking for a senior Embedded Linux security engineer in California to design hardware root of trust and secure boot from bootloader through the Linux kernel. You will implement dm-verity, encryption at rest, and TEE integrations such as OP-TEE, ensuring robust device security across production hardware.

You will collaborate with hardware and software teams, build automated signing pipelines in CI/CD, and support manufacturing with secure end-of-line test tooling.

Qualifications

• 6+ years of Embedded Linux development, BSP customization.
• 3+ years deploying device‑level security features in production hardware.
• Experience with ARM TrustZone and secure boot architectures.
• Experience with SELinux/AppArmor and Linux containment tools.

Responsibilities

• Design and implement hardware root of trust and secure boot from bootloader to Linux kernel.
• Develop, integrate, and maintain a TEE (OP-TEE) and Secure Applications.
• Enforce user-space isolation with SELinux/AppArmor, cgroups, namespaces, and seccomp.
• Build automated cryptographic signing pipelines in CI/CD using HSMs/secure vaults.
• Collaborate with manufacturing to burn eFuses/OTP and validate security features before shipping.

Job description

Job Description

• Platform Hardening & Architecture: Design and implement the Hardware Root of Trust and Secure Boot architecture from the first-stage bootloader through the Linux kernel.
• Storage & Integrity Management: Implement dm-verity for cryptographically verified read-only root filesystems and secure data encryption at rest.
• Trusted Execution Environments: Develop, integrate, and maintain a TEE (e.g., OP-TEE) and author Secure/Trusted Applications (TAs).
• 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.
• 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.
• 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‑of‑line (EOL) test software to validate security features before shipping.

Requirements

• Hardware Security Architecture: Deep understanding of modern processor security architectures, specifically ARM TrustZone (ARMv7-A / ARMv8-A, Exception Levels EL1-EL3).
• Sandboxing & Access Controls: Proven track record implementing SELinux/AppArmor policies and utilizing standard Linux containment tools (cgroups, namespaces).
• Build Automation: Proficiency with embedded Linux build automation frameworks like the Yocto Project (BitBake recipe design) or Buildroot.
• Programming: Advanced proficiency in C and strong scripting skills in Python or Bash.

Job Responsibilities

• System Resilience: Architect multi-slot boot recovery layouts (e.g., A/B partitioning) to guarantee fail‑safe resilience against failed OTA updates or corrupted boots.
• Core Experience: 6+ years of professional experience in Embedded Linux development, board bring‑up, and Board Support Package (BSP) customization.
• Security Focus: 3+ years of dedicated, hands‑on experience deploying device‑level security features into physical production hardware.
• Low-Level Systems: Expert knowledge of bootloader configurations (e.g., U-Boot Verified Boot, Barebox) and customizing the Linux kernel storage/security subsystem (dm-crypt, dm-verity).
• Education: Bachelor's or Master’s degree in Computer Science, Computer or Electrical Engineering, Mathematics, or a related field.
