About the role

Senior electrical safety engineer responsible for owning electrical safety controls for SpaceX’s large-scale AI infrastructure and Memphis-area supercomputing facilities; focuses on high-density critical power systems, NFPA 70E practices, and integration with data center electrical architectures.

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

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
