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, build, and deploy high-density modular power and compute infrastructure.
Embedded directly within the Spark Modular Data Center (MDC) Business Unit, the Senior Staff Mechanical Systems Engineer - Spark is a key technical engine supporting the mechanical, thermal, and fluid architecture of our MDC platform. You will sit at the crossroads of hardware, software, and physical infrastructure translating next-generation GPU compute workloads, cluster topologies, power envelopes, and cooling requirements into robust, high-performance liquid-cooled MDC system designs.
In this role, you will support the technical execution of current and future MDC architectures, collaborating closely with external design & engineering partners and internal R&D, Crusoe Industries (CI), Cloud Product, and Cloud Engineering teams to turn first-principles mechanical design into scalable product reality.

Bachelor's degree in Mechanical Engineering or a related field; Master's degree a plus.
8-12 years of mechanical engineering experience, with deep, hands-on expertise in fluid mechanics, heat transfer, structural integrity, and mechanical system dynamics.
Direct experience designing, validating, or integrating complex liquid-cooling loops (DLC, CDUs, pumping skids, heat exchangers, or hydronic systems).
Strong working understanding of thermal engineering fundamentals (heat transfer, CFD/thermal modeling concepts) sufficient to collaborate closely and speak the same technical language as dedicated thermal engineers — you don't need to be the thermal expert, but you need to design mechanical systems that hold up under their analysis.
Proficiency with mechanical CAD tools (e.g., SolidWorks, Creo, or Inventor) and familiarity with thermal-fluid simulation tools (e.g., ANSYS Fluent/CFX, 6SigmaET, or equivalent).
Working knowledge of relevant mechanical codes and standards (e.g., ASME B31.x piping codes, ASHRAE thermal guidelines, NFPA data center cooling requirements).
Demonstrated experience collaborating with external design & engineering partners while contributing to internal design iterations and CAD review workflows.
Comfort navigating fast-moving environments where physical hardware and compute infrastructure are co-developed concurrently.
