Protection & Controls Engineer - 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: We are seeking an Electrical Commissioning Engineer to execute the buildout, startup, and handover of electrical systems for SpaceXSI's high-performance data centers. This is a hands-on role where you will commission, test, troubleshoot, and turn over critical systems that support next-generation AI supercomputing infrastructure. You will work closely with construction, engineering, operations, EPC contractors, and OEM vendors to deliver safe, reliable, and high-quality electrical systems. This is a full-time, onsite role with travel to SpaceXSI data center construction sites across the United States. RESPONSIBILITIES: Execute all electrical commissioning activities for MV/LV switchgear, generators, UPS systems, PDUs, ATS/STS, transformers, relays, busway, and associated controls in hyperscale data center environments. Execute functional performance testing, pre-functional testing, site acceptance testing, load-bank testing, protection-relay testing, integrated system testing, and system turnover to operations. Troubleshoot and resolve complex electrical, controls, and process issues during pre-commissioning, commissioning, and startup phases. Develop and review

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 Battery Storage, 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 storage fleet as a power plant, not as an accessory: architecture, sizing, controls, safety case, and grid-forming behavior that lets the campus ride through compute step loads and generation contingencies. Own BESS architecture: pack-to-MV-transformer grouping, string composition, medium-voltage collection topology, string-level protection, and physical block layout including spacing per NFPA 855. Own sizing; translate compute duty cycles — step loads, training-job ramps, actual-versus-nameplate utilization — into power and energy requirements. Own inverter control strategy: grid-forming versus grid-following, droop and virtual inertia, fault-current contribution, ride-through, and coordination with generation governors and excitation. Own the plant controller and

ABOUT THE ROLE : The fire protection technician keeps facility fire and life safety systems working: fire suppression, sprinklers, fire alarm and detection, extinguishers, and related life safety equipment. This is a field role. You inspect, test, troubleshoot, and support the installation and commissioning of systems that protect people and high-density computing. GPU racks and industrial processes can and do catch fire. You will work with facilities, contractors, and the local fire marshal. You are not the design engineer of record. You are the technician who ensures the as-built system is installed, tested, and kept in service. RESPONSIBILITIES : Inspect, test, and maintain fire and life safety systems (sprinklers, suppression, alarms, detection, extinguishers) and close out deficiencies Support installation, upgrades, and commissioning of fire protection systems: walkdowns, device checkout, punch lists, functional tests, and turnover Verify that installed systems stay in working order and that impairments are logged, mitigated, and restored Work with facilities teams, fire contractors, and the authority having jurisdiction (fire marshal) on inspections, permits, impair
