We are looking for a Hardware Security Architect with deep RTL and SoC security expertise to join our hardware security team during a period of strong growth. Working closely with the security & certification team, you will own the architecture and design of our hardware Root of Trust, define SoC security requirements spanning secure boot, cryptographic IP, key storage, and lead the triage and mitigation of hardware vulnerabilities across both pre-silicon and fielded products. This is a hands‑on role for someone who enjoys translating high‑level security requirements into concrete RTL‑level architectures, stays current with the latest developments in silicon security and trust architectures, and is comfortable operating both independently and as part of a diverse, collaborative team in a fast‑paced environment.

Key Responsibilities

Strategy & Leadership: Define and lead the hardware security strategy and roadmap for the team in collaboration with the security & certification team

Architecture Design: Own the hardware Root of Trust (RoT)



design and architecture and define SoC hardware security architecture and requirements, covering secure boot, cryptographic IP integration, secure key storage and provisioning

Lifecycle Vulnerability Management: Lead the triage, analysis and mitigation of hardware weaknesses and vulnerabilities in both pre-silicon and fielded products

Innovation: Stay at the forefront of hardware security across silicon security, privilege boundaries and trust architectures

Compliance & Standards: Oversee hardware product compliance with public and private regulations

RTL & Microarchitecture Implementation: Translate high‑level security requirements into concrete RTL‑level hardware architectures, countermeasures, and microarchitectural mitigations
