About the role

Lead security architecture for Microsoft custom silicon and SoC platforms, translating product threats and platform security goals into actionable hardware, firmware, and software security architectures across concept to production and post-silicon closure.

Responsibilities

  • Lead end-to-end security architecture for complex SoCs and silicon subsystems from product requirements and threat analysis through architecture signoff, implementation, validation, production, and post-silicon issue resolution.
  • Define the SoC security framework, trust boundaries, security objectives, assets, attacker models, and hardware, firmware, and software responsibilities.
  • Lead threat modeling and security risk assessments covering hardware, firmware, software, microarchitectural, supply-chain, lifecycle, and physical attack surfaces; drive mitigations and residual-risk closure.
  • Architect hardware roots of trust, secure and measured boot, device identity and attestation, key management, secure provisioning, ownership transfer, lifecycle states, secure recovery, and firmware update mechanisms.
  • Define isolation and confidential-computing architecture, including security enclaves or trusted execution environments, memory and I/O protection, access control, privilege boundaries, virtualization, and multi-tenant security.
  • Define secure debug, telemetry, error handling, anti-rollback, tamper response, and manufacturing and field-service security requirements while preserving product diagnosability and supportability.
  • Define cryptographic services and acceleration requirements; evaluate algorithms, protocols, key hierarchies, entropy sources, and implementation tradeoffs for performance, power, area, assurance, and agility.
  • Assess side-channel, fault-injection, replay, rollback, and other physical or microarchitectural threats; partner with design and validation teams on mitigations and security test strategies.
  • Author clear, testable security requirements and architecture specifications, maintain requirements traceability, and establish review, verification, validation, and signoff criteria.
  • Evaluate internal and third-party security IP and vendor solutions; lead architecture reviews and provide data-driven recommendations spanning security assurance, functionality, PPA, cost, schedule, reuse, and risk.
  • Drive cross-functional and cross-company technical alignment, resolve ambiguous or conflicting security requirements, and influence product and platform direction at Principal scope.

Qualifications

  • Doctorate in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 3+ years technical engineering experience OR Master’s Degree in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 6+ years technical engineering experience OR Bachelor’s Degree in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 8+ years technical engineering experience OR equivalent experience
