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 conditionsEstablish 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 systemsLead 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 systemsQualify, train, and audit electrical workers as NFPA 70E Qualified Persons; develop and deliver electrical safety training for operators, technicians, contractors, and construction partnersReview and approve energized work, electrical switching, and commissioning procedures from a safety perspective; stop work when conditions do not meet electrically safe work practice requirementsEnsure proper grounding, bonding, equipotential bonding, and power quality monitoring/telemetry to prevent equipment damage and personnel injuryValidate ATS, generator, and UPS failover procedures for personnel safety during planned and unplanned transfers, including black-start, paralleling, and restoration sequencesPartner 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 LOTOConduct 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 storageInvestigate electrical incidents, near misses, shock events, and arc-flash events; drive root-cause analysis and corrective actionsMonitor 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 ratingsEstablish safe operating limits and emergency response procedures for electrical events, including arc flash, shock, power loss, battery incidents, and fire involving electrical equipmentEnsure 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 guidelinesCoordinate with contractors and vendors to enforce electrical safety requirements during installation, maintenance, and repairs on critical power infrastructureBasic Qualifications:Bachelor's degree in electrical engineering, electrical and computer engineering, electrical engineering technology, or engineering field5+ years of professional experience in electrical power systems, electrical safety, or critical-facility electrical operationsPreferred Skills and Experience:Direct ownership or administration of an NFPA 70E electrical safety program in an industrial, utility, or mission-critical environmentHands-on experience in data centers, critical facilities, or other high-availability electrical environmentsExperience with arc-flash studies, short-circuit analysis, and protective device coordination using ETAP, SKM PowerTools, EasyPower, or equivalentWorking knowledge of data center electrical architecture, including utility feeds, generators, paralleling switchgear, ATS, UPS, PDUs, RPPs, busway, STS, and battery energy storageFamiliarity with delta/wye transformers, motor control centers, protective relaying, facility grounding, and power qualityExperience creating and implementing electrical LOTO, switching procedures, and energized electrical work permit processesKnowledge of OSHA 1910.147, OSHA 1910.269/1910.333, NFPA 70, NFPA 70B, IEEE 1584, and NESC as applicableNFPA 70E related certifications (e.g., CESCP, CESW, or equivalent electrical safety credentials)PE (Professional Engineer) licenseCSP (Certified Safety Professional) or equivalent EHS credentialProficiency in AutoCAD Electrical, Revit, or similar electrical design toolsProficiency with PFMEA, root cause analysis, statistical process control, and structured problem-solving methodologiesExperience working with utility providers, electrical contractors, and commissioning agents on interconnection, cutovers, and live-facility workAbility to quickly assess an electrical issue in the field and guide technicians through safe troubleshooting and repairStrong interpersonal and collaborative skills, enthusiasm for the mission of enabling multi-planetary lifeAdditional Requirements:This is not a remote or hybrid position and will require relocation if not already local to the Memphis, TN areaPosition occasionally requires the ability to travel and support other critical computing infrastructureAbility to work extended hours and weekends as neededITAR Requirements:To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
