Staff Software Engineer, 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 Staff Security Software Engineer, you are fundamentally a systems engineer who operates with a security-first mindset. You will design, build, and deploy the core infrastructure and automation platforms that define Crusoe's security posture. Rather than operating as a traditional security auditor, you will act as a platform architect—engineering the foundational software systems that enable secure-by-default production environments. You will own the full engineering lifecycle—from high-throughput identity and secrets management systems and Kubernetes orchestration to the development of high-throughput data pipelines—ensuring that our architecture is both performant and impregnable.

• Tackle complex security and compliance puzzles at cutting-edge scale within cloud and distributed infrastructure.

• Collaborate with a brilliant, multidisciplinary team of engineers who are redefining compliance adherence for modern infrastructure.

• Have the freedom, autonomy, and responsibility to innovate, experiment, and heavily influence how Crusoe establishes its core security assurance pipelines.

• Advanced understanding of authentication, authorization at scale in distributed systems.

• Experience engineering security tools or telemetry platforms within large-scale AI/ML or high-performance computing environments.

• Active contributor to open-source security engineering projects or frameworks.
