About the job
Join our team as a Senior Hardware Security Engineer!
We are looking for two talented and experienced individuals who are eligible to work in the United States without requiring visa sponsorship or E-Verify. This position is fully onsite at our Seattle campus, requiring presence five days a week. Candidates must reside within a commutable distance (approximately 30 miles) from downtown Seattle.
Role Overview
The successful candidate will possess extensive expertise in hardware security and be able to clearly communicate the rationale behind their decisions. As a recognized expert, the Hardware Security Engineer will contribute to the creation of technical and business solutions, often being consulted for cross-functional projects and demonstrating the ability to work autonomously with minimal oversight.
In this role, you will earn the trust and respect of engineering teams and senior stakeholders through your leadership, accountability, and strategic insights, while ensuring excellence throughout the program lifecycle.
Please note: This is a 12-month engagement requiring onsite work in Seattle, WA, five days a week. Candidates must be located within a 30-mile radius of the client campus and must be authorized to work in the U. S. without sponsorship.
Your Responsibilities:
- Analyze System-on-a-Chip (SoC) security architectures to validate secure boot chains, root-of-trust enforcement, anti-rollback protections, and cryptographic controls at the silicon level.
- Validate hardware security requirements through hands-on testing of physical devices, evaluation boards, and chip samples across development and production lifecycles.
- Execute hardware security testing techniques, including fault injection attempts, debug interface probing (JTAG/BDM), and resistance validation against physical attacks.
- Review schematics, board layouts, and hardware designs to ensure correct implementation of secure key storage, tamper mitigations, and debug access restrictions.
- Verify manufacturing security processes by assessing secure provisioning flows, key injection procedures, and production lifecycle state transitions.
- Inspect manufactured hardware samples to detect unauthorized component substitution, malicious modification, or deviations from approved security designs.
- Assess cryptographic implementations (RSA, AES, HMAC, PQC) embedded in hardware and firmware to confirm secure key handling and isolation.
- Collaborate with silicon vendors, OEMs, and manufacturing partners to remediate security findings and validate corrective actions at the device level.
