About the role

Senior Staff Mechanical Systems Engineer focused on the Spark Modular Data Center platform, responsible for the mechanical, thermal, and fluid design of high-density liquid-cooled MDCs, and driving the mechanical/thermal roadmap from concept to production.

Responsibilities

  • Liquid Cooling System Design: Own system-level design for direct-to-chip (DLC) and hydronic infrastructure, including Coolant Distribution Units (CDUs), primary/secondary loops, flow rate balancing, pressure drop calculations, manifolds, and leak-detection mechanisms. Perform the thermal and fluid calculations — heat load modeling, flow network analysis, pump/heat-exchanger sizing — that turn GPU rack power and cooling requirements into concrete mechanical specifications.
  • First-Principles Mechanical Integration: Apply core mechanical engineering principles — fluid dynamics, thermodynamics, structural mechanics, vibration/transportation dynamics — to optimize containerized envelope design, structural integrity, and environmental resiliency.
  • Engineering Partner Engagement: Work with external design & engineering partners and internal teams to review, iterate, and refine CAD models, BIM files, 30/60/90/100% drawing packages, and manufacturing-ready documentation.
  • Design for Manufacturability (DFM): Partner with Crusoe Industries (CI) and Contract Manufacturers (CMs) to optimize pipe racks, modular connections, skid assemblies, and structural mating for rapid factory assembly and field commissioning.
  • Spark Platform Evolution: Drive the mechanical and thermal roadmap for future Spark generations, moving from current air-cooled baselines to next-gen high-density liquid-cooled architectures.
  • Mechanical–Thermal Interface Ownership: Own the mechanical design as it interfaces with compute, power, and networking constraints — ensuring rack layout, cabling, and enclosure design are mechanically sound and thermally validated; serve as the mechanical design authority for manufacturable production units.
  • Sustaining Engineering & Continuous Improvement: Provide sustaining mechanical engineering support for deployed Spark assets, investigate field issues, resolve design or component issues, implement ECOs, and feed field learnings back into future design iterations.

Qualifications

  • Bachelor's degree in Mechanical Engineering or a related field; Master's degree a plus.
  • 8-12 years of mechanical engineering experience with 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).
  • 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.
