Define multi-year identity, secrets, and PKI strategies to deliver scalable, secure-by-default primitives across the hyper-scale GPU fleet.
Drive strategic planning for fleet-wide runtime visibility, hardware roots of trust, secure boot, firmware update validation, and software supply chain verification.
Formally establish the long-term vision, leadership structure, and operational roadmap for infrastructure security posture and access governance.
Establish security architecture frameworks and governance for the control plane across public cloud environments and on-premise AI data center infrastructure.
Champion executive initiatives to eliminate standing admin privileges, implement zero-trust identity and access management, and enforce structural blast-radius boundaries.

Requirements

10+ years of progressive security engineering experience, including 5+ years leading second-line management structures or multi-team security organizations at hyper-scale cloud providers or infrastructure-intensive platforms.
Proven success in organizational architecture, hiring, developing, and mentoring engineering managers, and building scalable team structures.
Demonstrated track record of evaluating complex technical challenges from foundational principles and guiding engineering leaders to solve systemic architectural bottlenecks.
Excellence in partnering with cross-functional executive leaders, setting multi-year talent and resource allocation strategies, and translating infrastructure security risk into business context.
