Hardware Security Architect, Principal

Role overview

Own the security architecture for an AI accelerator platform from architectural design through production deployment. The work protects customer models and data, firmware, intellectual property, and device operation across the silicon and its surrounding systems. You’ll define security mechanisms, assess threats, and coordinate their implementation across engineering and manufacturing teams.

Responsibilities

- Define silicon security architecture, including secure boot, hardware root of trust, authenticated firmware, and chain of trust. - Design secure debug and manufacturing flows covering fuse programming, key provisioning, device identity, JTAG, scan access, and lifecycle states. - Protect AI models and weights with encryption and authentication; secure data paths including PCIe, CXL, on-chip fabric, and DRAM. - Develop protections such as key ladders, anti-rollback controls, secure DMA, and confidential memory regions. - Lead security reviews and threat modeling for physical attacks, fault injection, side channels, replay, firmware compromise, and supply chain risks. - Partner with firmware, software, architecture, design-for-test, validation, manufacturing, and cloud security teams to carry security through the product lifecycle.

Requirements

- At least 12 years of experience in hardware security architecture. - Deep knowledge of secure boot and hardware root-of-trust design. - Strong cryptography and key-management skills. - Hands-on experience with secure manufacturing processes. - Understanding of silicon bring-up in security-critical systems.

Nice to have

Experience with AI accelerators is preferred. Familiarity with NIST, FIPS, CCA, RISC-V or Arm security, post-quantum cryptography, or confidential AI is relevant. The role also calls for applying AI-assisted methods to threat modeling, security verification, coverage analysis, and documentation.

Benefits and work setup

Remote-first, with a company-provided computer and home-office setup. Benefits include company-paid medical, dental, vision, life, and disability coverage; supplemental coverage options; unlimited paid time off; 13 company holidays; competitive salary and equity; and a matched 401(k). Applicants must already be authorized to work in the United States; eligible H-1B transfers may be supported, but new visa sponsorship is unavailable.
