Role
Who you are
- Executive Security Leadership: 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
- Organizational Design & Manager Leadership: Proven success in organizational architecture, hiring, developing, and mentoring engineering managers, and building scalable team structures aligned with broader business objectives
- Strategic Vision & First-Principles Thinking: Demonstrated track record of evaluating complex technical challenges from foundational principles, guiding engineering leaders to solve systemic architectural bottlenecks without defaulting to off-the-shelf vendor playbooks
- Executive Stakeholder Management: Excellence in partnering with cross-functional executive leaders, setting multi-year talent and resource allocation strategies, and translating high-level infrastructure security risk into business context
- Technical Credibility: Broad architectural depth across Linux, hypervisors, container orchestration, IAM frameworks, PKI, workload identity, and hardware or network primitives, sufficient to guide senior leaders and evaluate high-level system design
- Location: In-person presence in the San Francisco Bay Area to partner closely with senior engineering and operational leadership
What the job involves
- 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
Our take
Crusoe is tackling one of the biggest challenges facing the digital age: the enormous energy demand of data centres and AI infrastructure. As AI models grow more powerful, they require immense computing power (and therefor electricity) to train and operate. This surge in energy use has put some pressure on power grids, driven up costs, and raised environmental concerns. Crusoe is on a mission to make this process more sustainable by finding smarter, cleaner, and more efficient ways to power the data centres that drive modern computing.
The company started out by putting wasted energy to work. Originally known as Crusoe Energy, it captured natural gas that would otherwise be burned off ("flared") at remote oil sites and used it to power modular data centres. Today, Crusoe has evolved into a major player in AI infrastructure, designing and operating large-scale data centres near renewable or stranded energy sources. It's now one of a handful of "neocloud" companies (next-generation cloud providers focused on flexible, efficient computing for AI workloads). And its facilities are helping tech giants like OpenAI handle the massive computing requirements of training advanced AI models.
Recently, Crusoe has attracted some huge investor attention, tripling its valuation to over $10B and raising almost $1.4B in its 2025 funding round. It's building OpenAI's first major US data centre campus and even experimenting with bold new frontiers. In partnership with Starcloud, Crusoe plans to deploy the world's first space-based cloud computing infrastructure, powered by solar energy and orbiting the Earth by 2027. If successful, this could redefine how and where computing happens, opening up a cleaner, virtually limitless source of energy for AI's next generation.
