About the role

What You’ll Be Working On

  • Design Ownership & First-Principles Engineering: Drive the medium- and low-voltage electrical architecture, structural enclosure design, and thermal management for Direct Liquid Cooling (DLC/CDU).
  • Design for Manufacturing (DFM): Embed DFM best practices into every design revision, ensuring engineering packages are optimized for high-volume production at Crusoe Industries and external manufacturing partners.
  • Safety & Compliance: Ensure all designs comply with applicable safety standards including UL, CE, NEC, NFPA, and OSHA for modular and containerized electrical equipment.
  • Factory Acceptance Testing (FAT): Own the development and continuous improvement of FAT protocols to verify electrical distribution, protection, UPS performance, and structural integrity before unit release.
  • External Partner Management: Serve as the primary engineering contact for all external design firms and specialty consultants, owning scope definition, deliverable quality, and schedule accountability.
  • Liquid Cooling Transition: Lead systems-level engineering for the shift from air-cooled units to DLC/CDU architectures, managing integration impacts on power density and structural loads.
  • Technical Documentation: Own the complete engineering design package for each Spark version, including drawings, specifications, BOMs, and interface control documents ready for manufacturing hand-off.

What You’ll Bring to the Team

Education: Bachelor's degree in Electrical Engineering, Mechanical Engineering, or a related discipline. A Master’s degree and an active Professional Engineer (PE) license are strongly preferred.

Experience: 10+ years of progressive engineering experience in data center design, modular infrastructure, or industrial power systems.

Partner Management: 10+ years of demonstrated experience managing external design engineering partners with direct accountability for budget and schedule.

Technical Depth: Mastery across medium-voltage power distribution, structural analysis for containerized systems, heat transfer fundamentals, and seismic/wind load calculations.

Safety Mastery: Expert knowledge of electrical safety standards (NFPA 70E), arc flash hazard analysis, and UL/CE compliance.

Software Proficiency: Proficiency with CAD/BIM platforms, electrical single-line design tools, and/or thermal simulation software.

Bonus Points:

  • Familiarity with the physical layer requirements of high-performance computing (HPC) and large-scale AI workloads.
  • Experience with agency certification strategies for modular electrical equipment in multiple global jurisdictions.
  • Track record of scaling a physical product from prototype through high-volume production.
