Senior Principal SoC Security Architect

Job Title

Senior Principal SoC Security Architect

Role Summary

Define and drive the Security Development Lifecycle (SDL) for Arm-based SoCs, spanning architecture, RTL, physical implementation, firmware, software, and production. This is a strategic, governance, and technical leadership role responsible for creating practical, scalable SDL processes and ensuring their adoption across multiple programs and teams.

Role is based in Cambridge with hybrid working. Relocation support and visa sponsorship are available for eligible candidates.

Experience Level

Senior level. The role expects extensive experience in SoC security, security process definition, and cross-team technical leadership.

Responsibilities

Lead SDL strategy and adoption for SoC development and verify consistent application of security practices across the organization.

• Establish and maintain an SDL framework covering the entire SoC lifecycle.
• Define security processes, checkpoints, sign-off criteria, and metrics for adoption and effectiveness.
• Lead cross-functional adoption across architecture, RTL, physical design, verification, firmware, software, and product teams.
• Set roles, accountability, and provide technical leadership and decision guidance on SDL matters.
• Provide frameworks and mentorship for threat modeling, risk assessment, and security reviews.
• Develop and mature hardware security verification and validation approaches.
• Continuously improve SDL based on feedback and evolving threats.

Requirements
