Embedded Systems Security Engineer

Job Description

Job Description

Roles & Responsibilities:

·       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.

·       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.

Qualifications:

·       Education: Bachelor’s degree in computer science, Computer Engineering, Electrical Engineering, or a related technical discipline (or equivalent practical experience).

·       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).

·       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/AppArmorpolicies and utilizing standard Linux containment tools (cgroups, namespaces).

·       Build Automation: Proficiency with embedded Linux build automated frameworks like the Yocto Project (BitBake recipe design) or Buildroot. Programming: Advanced proficiency in C and strong scripting skills in Python or Bash.

Preferred Qualifications:

·       Cryptography Expertise: Strong foundational knowledge of symmetric/asymmetric cryptography, hashing algorithms (SHA-256/384), public key infrastructure (PKI), and handling physical Hardware Security Modules (HSMs).

·       Manufacturing Scale: Prior experience working with Contract Manufacturers (CMs) or internal factory lines to deploy secure key-injection and fuse-burning protocols.

·       Advanced Sandboxing: Experience with embedded container runtimes (e.g., LXC, crun) or lightweight sandboxing frameworks tailored for resource-constrained architectures.

·       Anti-Rollback Protection: Experience designing secure versioning and hardware-enforced anti-rollback strategies for OTA updates.
