Job Overview
We are looking for an SDL Architect to define and drive the Security Development Lifecycle for Arm-based SoCs.
This is a strategy, governance, and leadership role. You will define how security is coordinated across the SoC lifecycle, from architecture through RTL, physical build, software, and production, and lead its adoption across teams.
A key part of the role is to develop practical, scalable, and effective SDL processes that can be implemented across multiple programs and teams. The focus is on making security processes usable and repeatable in real development environments. You will act as a senior technical leader, setting direction, driving alignment, and ensuring consistent application of security practices throughout the organization.

- Establish and uphold the SDL framework for Arm SoC development throughout the entire lifecycle
- Establish security processes, checkpoints, and sign-off criteria, ensuring alignment with industry standards
- Develop practical and scalable SDL processes that function across multiple programs and teams
- Lead adoption across architecture, build, verification, physical build, firmware, software, and product teams
- Define roles and accountability for security across teams and provide clear technical leadership
- Act as the central authority for SDL regarding SoCs, guiding teams and driving consistent decision-making
- Provide frameworks and mentorship for threat modeling, risk assessment, and security reviews
- Ensure SDL coverage throughout the entire stack including hardware, software, and production
- Develop and mature security verification methodology for SoCs
- Define metrics to track SDL adoption and efficiency
- Continuously improve SDL based on feedback and evolving risks
- Advocate for robust security measures throughout engineering teams
Necessary Skills And Experience
- Prior experience as a SoC Security Architect or similar role
- Strong understanding of the full SoC lifecycle including architecture, RTL, physical build, software, and production
- Experience defining or influencing security processes, frameworks, or methodologies at an organizational level
- Proven ability to lead and influence across multiple teams without direct authority
- Demonstrated history of promoting consensus and influencing choices among architecture, building, verification, physical implementation, firmware, software, and product teams
- Experience with threat modeling and risk assessment
- Familiarity with hardware and system security concepts such as secure boot, root of trust, and key management
- Understanding of secure provisioning, manufacturing, and lifecycle management
- Exposure to hardware security verification or validation approaches
