ABOUT THE ROLE:
Join the High Power Engineering team supporting SpaceXAI to design, build, operate, and maintain electrical infrastructure for AI training campuses. As a Power System Engineer on the Transmission & Distribution team, you will work with a small on-site team to scale high-capacity power systems on a schedule set by compute demand. The position is based in Memphis, TN, with potential travel to other sites.
RESPONSIBILITIES:
- Own the single model of record for the Memphis campus: load flow, short circuit, coordination, arc flash, motor starting, harmonics, transient stability, and EMT studies for grid-forming inverter interaction with generation.
- Create and maintain sitewide power budgets, monitoring, and metering for mission-critical assets to optimize visibility and efficiency.
- Perform detailed analysis on electrical power systems: one-lines, three-lines, studies that justify relay settings, and as-built model updates after commissioning.
- Feed interconnection studies, relay settings, arc-flash labels, and Battery Storage sizing from the same model. Do not allow shadow models in other pillars.
- Develop standardized study cases for hall add, storage dispatch, islanding, and black start.
- Ensure compliance with NFPA 70, 70B, 70E, NESC, and IEEE standards, prioritizing safety and engineering excellence.
BASIC QUALIFICATIONS:
- Bachelor's degree in electrical engineering, computer engineering, physics, or another engineering discipline.
- 3+ years of experience in power systems design, analysis, and studies, with a focus on high-power, high-voltage systems.
PREFERRED SKILLS AND EXPERIENCE:
- Experience with power systems analysis software and tools: ETAP, SKM, EasyPower, PowerWorld, Matlab, PSCAD, PSS/E, ASPEN, Simulink, etc.
- Experience performing load flow, short-circuit, arc-flash, coordination, and transient stability studies.
- Familiarity with industrial power systems up to 345 kV, including switchgear, transformers, BESS, VFDs, motors, distribution systems, UPS/emergency backups, power generation, relaying, metering, protective devices, and networking.
- Professional Engineering license or intention to actively seek a PE license.
- Experience with CAD software: Revit, AutoCAD, NX, etc.
- Demonstrated initiative, creative problem-solving, and strong analytical/engineering fundamentals.
ADDITIONAL REQUIREMENTS:
