Principal Hardware Security Architect

Quick Facts

• Role: Principal Hardware Security Architect

• Focus: Hardware security architecture for an AI accelerator platform (secure silicon through production deployment)

Description

Own the hardware security architecture for an AI accelerator platform, ensuring protection of customer models, user data, firmware, intellectual property, and secure operation across the product lifecycle. Define and deliver security mechanisms spanning secure boot, hardware root of trust, authenticated/measured firmware, secure manufacturing, device identity, and protected debug and lifecycle access. Lead security reviews and threat modeling, then collaborate across teams to embed security from architecture to production.

Responsibilities

• Define overall silicon security architecture

• Own secure boot, hardware root of trust, chain of trust, authenticated firmware, and measured boot

• Own secure debug, secure manufacturing, fuse programming, key provisioning, and device identity

• Own key ladders, anti-rollback protections, JTAG security, scan access control, and lifecycle states

• Protect AI assets via weight encryption and weight authentication

• Secure data in motion and within the system (link encryption, PCIe/CXL security, on-chip fabric security)

• Own DRAM encryption, secure DMA, secure memory regions, and confidential computing techniques

• Perform architecture security reviews and develop attack models

• Mitigate physical attacks, fault injection, side-channel attacks, replay attacks, firmware compromise, and supply-chain attacks

• Partner with firmware, software, architecture, DFT, validation, manufacturing, and cloud security teams

• Stay current with NIST/FIPS/CCA/RISC-V and Arm security standards, plus post-quantum cryptography and confidential AI

• Use AI-assisted techniques for threat modeling, security verification, coverage analysis, and documentation

Requirements

• 12+ years of experience in hardware security architecture

• Deep expertise in secure boot and hardware root of trust design

• Strong cryptography and key management ability

• Hands-on experience with secure manufacturing processes

• Solid grasp of silicon bring-up in a security-critical context

Benefits

• Fully company-paid medical, dental, and vision insurance (including dependents)

• Company-paid life and disability coverage, with voluntary options

• Supplemental hospital, critical illness, and accident coverage

• Unlimited paid time off; 13 paid company holidays

• Remote-first culture with company-provided computer and home office setup

• Competitive salary and equity; 401(k) with company matching (eligible from day one)

• Visa support: no new sponsorship, but H-1B transfers may be facilitated for eligible candidates
