About the role
SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.
SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.
POWER SYSTEMS ENGINEER, TRANSMISSION & DISTRIBUTION
Join the High Power Engineering team supporting SpaceXSI 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 such as ETAP, SKM, EasyPower, PowerWorld, Matlab, PSCAD, PSS/E, ASPEN, and/or Simulink
- 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 such as Revit, AutoCAD, and/or NX
- Demonstrated initiative, creative problem-solving, and strong analytical/engineering fundamentals
ADDITIONAL REQUIREMENTS
- Perform hands-on work in all environments (heat, cold, rain), in tight quarters or at heights
- Work extended hours and weekends as needed to support construction, energization, and operations
- Remain focused in hazardous environments while wearing appropriate PPE
- Lift up to 25 lbs unassisted
- Provide 24/7 on-call support for emergencies
- Willing to work on-site in Memphis, TN – this is not a remote or hybrid role
- Travel up to 25% for factory witness testing, vendor and OEM engagement, and supporting other sites
- Valid driver's license
