About the Job

Requirements

A bachelor's degree in Electrical Engineering, Computer Engineering, Physics, or another engineering discipline is required.
At least 3 years of experience in power systems design, analysis, and studies, focused on high-power, high-voltage systems.
Perform hands-on work in varied environments, including heat, cold, rain, tight quarters, and heights.
Work extended hours and weekends as needed to support construction, energization, and operations.
Remain focused in hazardous environments while wearing appropriate personal protective equipment.
Lift up to 25 pounds unassisted.
Provide 24/7 on-call support for emergencies.
Work on-site in Memphis, Tennessee; the role is not remote or hybrid.
Travel up to 25% for factory witness testing, vendor and original equipment manufacturer engagement, and support of other sites.
Hold a valid driver's license.

Responsibilities

Own and maintain the single model of record for the Memphis campus, including load flow, short circuit, coordination, arc flash, motor starting, harmonics, transient stability, and electromagnetic transient 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 electrical power-system analysis, including one-line and three-line diagrams, studies that justify relay settings, and as-built model updates after commissioning.
Use the same model for interconnection studies, relay settings, arc-flash labels, and battery energy storage system sizing; prevent shadow models in other groups.
Develop standardized study cases for hall additions, storage dispatch, islanding, and black start.
Ensure compliance with NFPA 70, 70B, 70E, the National Electrical Safety Code, and IEEE standards, prioritizing safety.

Desired Qualifications

Experience with power systems analysis software and tools such as ETAP, SKM, EasyPower, PowerWorld, MATLAB, PSCAD, PSS/E, ASPEN, 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, battery energy storage systems, variable-frequency drives, motors, distribution systems, UPS and emergency backup systems, power generation, relaying, metering, protective devices, and networking.
Hold a Professional Engineer license or intend to actively seek one.
Experience with computer-aided design software such as Revit, AutoCAD, or NX.
Demonstrate initiative, creative problem-solving, and strong analytical and engineering fundamentals.

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
