• Own the electrical architecture from the medium-voltage bus to the GPU rack, including topology, redundancy and standards
• Set and defend the redundancy basis, proving split-feed and cross-feed schemes against bus, transformer and switchgear loss
• Establish the campus electrical design standard, including grounding, insulation coordination and arc-flash boundaries
• Own the interface with the compute organization on rack density, step-load behavior and power capping
• Own the interface with mechanical and cooling engineering on CDU, sidecar and pump electrical loads
• Lead design reviews with EPCs, OEMs and owner's engineers; approve vendor drawings and factory acceptance tests
• Direct Design, Commissioning, R&D, BIM and Protection & Controls engineers on the Data Center team
• Keep hall design, interconnection and storage dispatch on one model of record with Transmission & Distribution and Battery Storage leads
• Ensure compliance with NFPA 70, 70B, 70E, NESC and IEEE standards

• Bachelor's degree in electrical engineering, computer engineering, physics or another engineering discipline
• 10+ years of electrical power design experience, focused on high-power, high-voltage or mission-critical systems
• Experience owning medium-voltage distribution architecture at 10 kV to 35 kV class
• Perform hands-on work in all environments (heat, cold, rain), in tight quarters or at heights
• Remain focused in hazardous environments while wearing appropriate PPE
• Lift up to 25 lbs unassisted
• Valid driver's license
• Willing to work on-site in Memphis, TN

Nice to have
