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
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
