Principal Sustaining Engineering Manager - Spark

The posting, as Crusoe wrote it

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 the Role

Crusoe is a vertically integrated AI Factory company accelerating energy and compute infrastructure. We believe that “speed is the only moat” and our vertical integration allows us to design, manufacture, and deploy modular power and compute infrastructure at market leading speed and cost.

We are seeking a Sustaining Engineering Leader to own how Spark physical modules perform post-deployment and drive continuous improvement. While Product Management defines future generations and NPI delivers them for production, you own each generation once it ramps: fleet reliability, field failures, configuration, component obsolescence, and the design modifications required for full service life performance.

In this role, “hardware” and “product” refers to the physical infrastructure of the Spark module: structural steel modules, RPPs, DLC cooling loops, CDUs, chillers, piping headers, electrical and mechanical systems, and power distribution gear. Compute hardware (servers, GPUs, storage, networking, and rack specifications) is owned by Cloud Product. Sitting on the Spark design engineering team, you capture how deployed Spark modules perform in service and aggregate the lessons learned and required changes into the design process, so the next version is more reliable, serviceable, and cost-effective. Working with Data Center Facility Operations and Field Operations, you are the definitive evidence source for Product Management and NPI, turning field data into design requirements and acceptance criteria. You start as the single-threaded leader of this function and build the team as the fleet expands.
