Embedded Systems Security Engineer

We are looking for an Embedded Systems Security Engineer to implement a security solution to harden our next-generation embedded Linux platform. 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 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., Need highly skilled and analytical Digital Key Engineer to lead the implementation, validation, and debugging of next-generation vehicle access systems. Person will be responsible for ensuring seamless, secure interoperability between smartphone devices and vehicle architectures and will serve as the core technical expert for root-cause analysis, defect triage, and physical/protocol-layer timing analysis across NFC, BLE, and UWB channels, closely aligning with Car Connectivity Consortium (CCC) standards.

• 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/AppArmor policies 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., * 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
