Principal Design Engineer

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. About This Role: Crusoe is a vertically integrated AI Factory company with a mission to accelerate the abundance of energy and intelligence. Our competitive advantage— "Speed is the only moat" —is directly tied to our ability to rapidly design, manufacture, and deploy our own modular power and compute infrastructure. We are seeking a Principal Design Engineer to own the full-lifecycle engineering design of our "Spark" modular data center (MDC) product line. You will be the technical authority across electrical, mechanical, thermal, and structural domains and the primary engineering interface to our external design and contract manufacturing partners. You will translate aggressive product roadmap requirements into manufacturable, deployable, and safe physical systems that power the next generation of AI workloads.
