Job description

• As a GPU-cloud provider, Crusoe’s infrastructure is our product. Infrastructure Security Engineering is a critical executive domain in our security organization. Unlike traditional enterprise cloud security functions that act as passive auditors asking other teams to fix bugs, this is a strategic platform engineering organization. As Director of Infrastructure Security, you will define organizational strategy, scale leadership structures, and lead an expanding organization responsible for foundational security strategy across our hyper-scale fleet
• Reporting directly to the Senior Director of Security Engineering, you will own the long-term strategic vision, organizational architecture, and executive execution across two core pillars: Platform Security Services and Cloud Security Access and Posture Governance. Leveraging extensive executive leadership experience, you will establish multi-year roadmaps, empower engineering managers, and build out high-performing organizational structures required to scale with Crusoe’s growth
• Organizational Strategy & Manager Leadership: Design and scale dedicated engineering domains across both pillars. Hire, mentor, and empower engineering managers and senior leaders, establishing clear organizational accountability, career paths, and leadership governance as Crusoe scales
• Executive Alignment & Resource Allocation: Own multi-year strategic roadmaps, high-level domain metrics, and organizational risk reduction goals. Translate complex technical infrastructure risks into strategic business priorities and resource investments for executive stakeholders
• Technical Vision & Governance: Set long-term architectural vision, applying first-principles strategy to guide engineering leadership, challenge legacy norms, and ensure all security initiatives align with Crusoe’s overarching mission
• Identity, Secrets & PKI Strategy: Define the multi-year identity and access roadmap, ensuring the organization delivers scalable, secure-by-default primitives across the hyper-scale GPU fleet
• Fleet Security & Sensor Strategy: Drive strategic planning and organizational alignment for fleet-wide runtime visibility, empowering engineering teams to deploy security sensors and kernel-level protections at scale
• Hardware, Firmware & Supply Chain Governance: Establish organizational standards, risk policies, and oversight frameworks for hardware roots of trust, secure boot, firmware update validation, and software supply chain verification across custom GPU nodes and networks
• Organizational Strategy & Growth: Formally establish the long-term vision, leadership structure, and operational roadmap for this function, driving sustainable organizational scale across Crusoe’s infrastructure security domain
• Control Plane & Cloud Security Governance: Establish high-level security architecture frameworks and governance for Crusoe’s control plane across public cloud environments and multi-gigawatt on‑premise AI data center infrastructure
• Zero-Trust & IAM Strategy: Champion executive initiatives to eliminate standing admin privileges and long-lived secrets, enabling leadership teams to deliver automated, just-in-time access engines and least-privilege models
• Systemic Risk & Isolation Governance: Oversee the identification and mitigation of architectural risks, driving cross-functional alignment on tenant control plane isolation, decoupling execution environments, and enforcing structural blast-radius boundaries natively through Infrastructure-as-Code strategy
