When you join ALTEN Technology USA, you’ll collaborate on some of the world’s toughest engineering challenges, supported by mentorship, career growth opportunities, and comprehensive benefits. We take pride in fostering a culture where employees feel valued, supported, and inspired to grow.

Workplace: On-Site, 5 days
Location: Foster City, CA

We are looking for an Embedded Linux Security Engineer to implement 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.

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.

Required 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/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.

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.

Salary Range

• $120,000 - 150,000
• The actual salary offered is dependent on various factors including, but not limited to, location, the candidate’s combination of job‑related knowledge, qualifications, skills, education, training, and experience
