Sr. Electrical Safety Engineer (AI Supercomputer)

SR. 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
• Investigate electrical incidents, near misses, shock events, and arc-flash events; drive root-cause analysis and corrective actions
• Monitor and mitigate electrical hazards associated with cooling failures, thermal runaway in energy storage, hot work near energized equipment, and extreme temperature/humidity conditions that degrade insulation, PPE, and equipment ratings
• Establish safe operating limits and emergency response procedures for electrical events, including arc flash, shock, power loss, battery incidents, and fire involving electrical equipment
• Ensure compliance with applicable codes and standards, including NFPA 70 (NEC), NFPA 70E, NFPA 70B, OSHA 1910 Subpart S, IEEE, IEC, local building/fire codes, and data-center industry guidelines
• Coordinate with contractors and vendors to enforce electrical safety requirements during installation, maintenance, and repairs on critical power infrastructure

BASIC QUALIFICATIONS:

• Bachelor's degree in electrical engineering, electrical and computer engineering, electrical engineering technology, or engineering field
• 5+ years of professional experience in electrical power systems, electrical safety, or critical-facility electrical operations

PREFERRED SKILLS AND EXPERIENCE:

• Direct ownership or administration of an NFPA 70E electrical safety program in an industrial, utility, or mission-critical environment
• Hands-on experience in data centers, critical facilities, or other high-availability electrical environments
• Experience with arc-flash studies, short-circuit analysis, and protective device coordination using ETAP, SKM PowerTools, EasyPower, or equivalent
• Working knowledge of data center electrical architecture, including utility feeds, generators, paralleling switchgear, ATS, UPS, PDUs, RPPs, busway, STS, and battery energy storage
• Familiarity with delta/wye transformers, motor control centers, protective relaying, facility grounding, and power quality
• Experience creating and implementing electrical LOTO, switching procedures, and energized electrical work permit processes
• Knowledge of OSHA 1910.147, OSHA 1910.269/1910.333, NFPA 70, NFPA 70B, IEEE 1584, and NESC as applicable
• NFPA 70E related certifications (e.g., CESCP, CESW, or equivalent electrical safety credentials)
• PE (Professional Engineer) license
• CSP (Certified Safety Professional) or equivalent EHS credential
• Proficiency in AutoCAD Electrical, Revit, or similar electrical design tools
• Proficiency with PFMEA, root cause analysis, statistical process control, and structured problem-solving methodologies
• Experience working with utility providers, electrical contractors, and commissioning agents on interconnection, cutovers, and live-facility work
• Ability to quickly assess an electrical issue in the field and guide technicians through safe troubleshooting and repair
• Strong interpersonal and collaborative skills, enthusiasm for the mission of enabling multi-planetary life

ADDITIONAL REQUIREMENTS:

• This is not a remote or hybrid position and will require relocation if not already local to the Memphis, TN area
• Position occasionally requires the ability to travel and support other critical computing infrastructure
• Ability to work extended hours and weekends as needed
