Director, Infrastructure Security

Crusoe is on a mission to accelerate the abundance of energy and intelligence . As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster. We're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that — with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI. We're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services. If you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe.

As a GPU-cloud provider, Crusoe’s infrastructure is our product. Infrastructure Security Engineering is arguably the most critical domain in our security engineering organization.   Unlike traditional enterprise cloud security functions that act as passive auditors asking other teams to fix bugs, this is an elite engineering and software development organization . You will lead a dedicated team of 5–6 infrastructure security engineers who design, build, and operate foundational security layers across our hyper-scale fleet. This role offers a high-impact organizational leadership opportunity: inheriting an established team of talented engineers, sharpening technical focus, resolving execution friction, and instilling a high-velocity software delivery culture to turn this core group into an elite, world-class engineering unit.   Reporting directly to the Senior Director of Security Engineering , you will own two core pillars: Platform Security Engineering and Infrastructure Security Access and Posture Management . A Note From the Hiring Manager "Infrastructure Security Engineering at Crusoe is an active software engineering discipline, not a pure ‘cloud security’ function. We don't throw tickets over the fence - we build the foundational cryptographic, identity, access, and runtime layers that make our GPU-cloud VM and baremetal offerings secure by default. I come from a deep product and infrastructure security background, and I hold strong, battle-tested opinions on how infrastructure security should be engineered and operated. I am looking for a Director who can dive into the technical details, establish clear architectural direction, and transform an existing team into a high-performance engineering engine. Once aligned, you will have my full support, dedicated headcount, and total executive backing to build and scale one of the premier infrastructure security teams in the AI industry."   What You'll Be Working On: 1.

Leadership, Turnaround & Talent Elevation Organizational Transformation: Inherit, lead, and mentor an existing team of 5–6 infrastructure security engineers. Diagnose execution bottlenecks, resolve cultural alignment issues, and elevate the team into a high-throughput engineering org. Engineering Rigor & Velocity: Transition the team from reactive operational task handling to a proactive platform engineering model with clear shipping cadences, code quality standards, and architectural roadmaps. Strategic Growth & Hiring: Establish clear accountability, strategically hire additional junior talent to complement existing strengths, systems security, and automation   2. Platform Core Security Services (Foundational Engineering) Identity, Secrets & PKI: Build, operate, and scale core identity and crypto primitives,
