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. ABOUT THE ROLE: Join the High Power Engineering team supporting SpaceXSI to design, build, operate, and maintain electrical infrastructure for AI training campuses. As a Ops/Build 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: Take high- and medium-voltage assets from steel in the ground to carrying load, then own their reliability in operation. Own the substation and transmission energization plan: pre-energization checks, phasing verification, synchronizing checks, and staged load ramp. Direct NETA acceptance testing on breakers, transformers, GIS, instrument transformers, arresters, and cable systems. Execute relay end-to-end testing, transfer trip verification, and point-to-point SCADA and telemetry checkout with the site and the utility. Coordinate outages and switching with the utility; write and own clearance and switching procedures. Execute the electrical safety program in the field: arc-flash labeling currency, energized work permitting, and switching authorizat…
