About the role
- 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.
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.
Requirements
- 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
- U.S. citizen or national, U.S. lawful permanent resident, Refugee, or Asylee, or be eligible to obtain required authorizations from the U.S. Department of State
Preferred qualifications
- 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
- 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
Workplace
- 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
