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 Engineer - Detection & Response at Crusoe, you will serve as a primary architect of our defense, safeguarding our customers and our mission to align the future of computing with the future of the climate. In this high-impact, full-time role, you will influence our overarching detection strategy by designing, tuning, and validating complex correlation models to stay ahead of an ever-evolving threat landscape. You will bridge the gap between high-level strategy and hands-on execution, building the very technologies that identify and neutralize risks before they manifest.
The ideal candidate is a seasoned security expert who balances deep technical mastery in Detection as Code with the leadership presence to mentor peers and partner with cross-functional teams. You will drive massive projects—from building open-source security observability at scale to integrating AI into our response workflows—ensuring that Crusoe’s security posture is as innovative as our energy solutions. If you are an automation-first engineer who thrives on solving complex forensic puzzles and building resilient systems, you will play a foundational role in our continued growth.
