Power System Engineer (Transmission & Distribution) - Memphis

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 Lead Engineer for Transmission & Distribution, 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 everything from generation terminals and the point of interconnection down to the medium-voltage bus: high-voltage switchyards, collector transmission, main power transformers, and the utility relationship that determines whether the campus energizes on schedule. Own high-voltage switchyard architecture: bus configuration, GIS versus AIS tradeoffs, bus sectionalizing, and fault-current management. Lead the interconnection process with the local distributor and balancing authority, including application, system impact and facilities studies, protection philosophy alignment, telemetry and metering, and technical exhibits to the service agreement. Own campus protection philosophy and the settings management database served to Data Center and Battery Storage

ABOUT THE ROLE: Join the High Power Engineering team to design, set, commission, and maintain protection and control systems for large electrical infrastructure. As a Protection & Controls Engineer, you will own schemes and settings from the transmission interconnection through distribution, on-site generation, and battery energy storage, down to medium- and low-voltage buses serving data halls and other mission-critical loads. The position is based in Memphis, TN, with potential travel to other sites. RESPONSIBILITIES: Develop protection philosophy, one-line and three-line diagrams, DC control schematics, wiring diagrams, and relay panel layouts for the electrical system from the utility interconnection to facility buses. Calculate, implement, and maintain protective relay settings and logic for transmission lines, buses, power transformers, distribution feeders, generators, and battery energy storage / inverter-based resources. Specify relays, current and voltage transformers, trip circuits, lockout schemes, breaker-failure protection, and communications-assisted schemes (permissive, blocking, transfer trip). Perform short-circuit, protective-device coordination, and arc-f

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 author
