Electrical Safety Engineer

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 enabling human life on Mars.

ELECTRICAL SAFETY ENGINEER (AI SUPERCOMPUTER) 

The Environmental Health and Safety team is seeking a highly driven electrical safety engineer to own electrical safety controls throughout the expansion of SpaceX's large-scale AI infrastructure and supercomputing facilities in the Memphis area. This role is critical in ensuring high-density critical power systems meet rigorous personnel-protection and control-reliability requirements, enabling the safe, rapid scaling of compute capacity. The ideal candidate will have a comprehensive understanding of data center electrical system architecture, NFPA 70E electrical safety work practices, and the hazards associated with UPS, PDUs, switchgear, generators, and energy storage systems.

RESPONSIBILITIES:

• Own the site electrical safety program in accordance with NFPA 70E, including shock protection, arc-flash protection, energized electrical work permits, approach boundaries, and electrically safe work conditions
• Establish and maintain lockout/tagout (LOTO) procedures, switching orders, and live-dead-live verification practices for UPS, PDUs, RPPs, busway, switchgear, transformers, automatic transfer switches (ATS), generators, and battery energy storage systems
• Lead arc-flash hazard analysis and incident energy studies (IEEE 1584), maintain equipment labeling, and define PPE categories, working distances, and restricted/limited approach boundaries for AC and DC systems
• Qualify, train, and audit electrical workers as NFPA 70E Qualified Persons; develop and deliver electrical safety training for operators, technicians, contractors, and construction partners
• Review and approve energized work, electrical switching, and commissioning procedures from a safety perspective; stop work when conditions do not meet electrically safe work practice requirements
• Ensure proper grounding, bonding, equipotential bonding, and power quality monitoring/telemetry to prevent equipment damage and personnel injury
• Validate ATS, generator, and UPS failover procedures for personnel safety during planned and unplanned transfers, including black-start, paralleling, and restoration sequences
• Partner with design, construction, and commissioning teams to integrate electrical safety into new builds and expansions: one-line diagrams, protective device coordination, short-circuit studies, temporary power, and construction LOTO
• Conduct structured risk assessments of electrical systems, including Failure Mode and Effects Analysis (FMEA) and electrical hazard assessments for medium- and low-voltage distribution, DC plants, and energy storage
