JOB TITLE: Embedded Systems Security Engineer
LOCATION: Foster City, CA (Onsite)
PAY RANGE: $87 - $97/hr.
DURATION: 6 Months
TOP 3 SKILLS:
- 6+ years of Embedded Linux development, board bring-up, and BSP customization experience.
- 3+ years of hands-on experience deploying device-level security features into production hardware.
- Advanced proficiency in C, Python, or Bash, with expertise in Linux security, bootloaders, ARM TrustZone, and Yocto Project or Buildroot.
Job Description:
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.
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.
BENEFITS SUMMARY:
Individual compensation is determined by skills, qualifications, experience, and location. Compensation details listed in this posting reflect the base hourly rate or annual salary only, unless otherwise stated. In addition to base compensation, full-time roles are eligible for Medical, Dental, Vision, Commuter and 401K benefits with company matching.

Senior Level Systems Security Engineer Jobs: Frequently Asked Questions
How do I get a senior level systems security engineer job?
Employers at this level look for engineers who have led security initiatives end to end, not just contributed to them. Demonstrated ownership of architecture reviews, threat modeling programs, or incident response frameworks carries more weight than certifications alone. Candidates who can show they have mentored junior engineers or influenced security standards across an organization consistently stand out in the screening process.
Which companies hire senior level systems security engineers?
Companies hiring senior level systems security engineers right now include MTSI, VTG Defense, and HP, based on current listings on Migrate Mate as of November 2026. Hiring at this level comes primarily from large enterprises, defense contractors, cloud platform providers, and financial institutions that maintain dedicated security engineering functions with dedicated senior headcount.
Are there remote senior level systems security engineer jobs?
Yes, remote work is well established at this level, particularly for roles focused on cloud security, detection engineering, and policy development. About 0% of senior level systems security engineer openings are remote or hybrid as of November 2026, though roles involving classified environments, on-premises infrastructure, or sensitive government systems tend to require on-site presence.
What makes a systems security engineer role senior level?
Senior level roles are defined by scope and ownership rather than task execution. Engineers at this level are expected to set the technical direction for security programs, make architectural tradeoffs independently, and serve as a primary escalation point for complex vulnerabilities or incidents. Mentoring mid-level engineers and contributing to hiring decisions, security roadmaps, or engineering standards are also common expectations that distinguish senior roles from mid-level ones.
Which industries hire the most senior level systems security engineers?
Senior level systems security engineer roles concentrate in Manufacturing, Science & Research, and Staffing & Recruiting, based on current listings on Migrate Mate as of November 2026. These sectors drive demand because they operate large, regulated, or high-value infrastructure that requires experienced engineers capable of designing and owning enterprise-grade security programs rather than executing defined playbooks.
