About the Job

Requirements

A bachelor's degree in electrical engineering is required.
At least five years of experience in commissioning for electrical systems is required.
Willingness to travel extensively and work extended hours, nights, and weekends during critical commissioning and startup windows.
Ability to travel extensively to SpaceXSI construction sites and remain onsite for extended periods during peak commissioning phases.
Physical capability to work in industrial environments, climb ladders and stairs, lift moderate loads up to 50 pounds, and wear full personal protective equipment for long durations.
A valid driver's license and ability to meet SpaceXSI's driver eligibility requirements are required.

Responsibilities

Execute electrical commissioning activities for medium- and low-voltage switchgear, generators, uninterruptible power supply systems, power distribution units, automatic and static transfer switches, transformers, relays, busway, and associated controls in hyperscale data center environments.
Execute functional performance testing, pre-functional testing, site acceptance testing, load-bank testing, protection-relay testing, integrated system testing, and system turnover to operations.
Troubleshoot and resolve complex electrical, controls, and process issues during pre-commissioning, commissioning, and startup phases.
Develop and review detailed commissioning test procedures, scripts, checklists, and documentation in alignment with project specifications, industry standards, and SpaceXSI requirements.
Coordinate with engineering, procurement, and construction contractors, original equipment manufacturers, design engineers, and SpaceXSI stakeholders for system energization, startup sequences, and integrated system validation.
Enforce adherence to lockout/tagout, National Fire Protection Association, Occupational Safety and Health Administration, and SpaceXSI safety protocols; participate in daily safety briefings and job hazard analyses.
Maintain as-built documentation, test records, issue logs, and final commissioning reports.
Support and deliver training programs for operations and maintenance teams on commissioned systems.
Participate in constructability reviews, design feedback sessions, and lessons-learned meetings to improve installation quality and future project execution.
Support commissioning schedules and punch-list resolution to meet project timelines.

Desired Qualifications

Working knowledge of commissioning test equipment, including power analyzers, insulation testers, hipot testers, torque tools, infrared cameras, load banks, and relay test sets, or demonstrated aptitude to learn it in the field.
Familiarity with relevant codes and standards, including the National Electrical Code, National Fire Protection Association standards 70, 70B, and 70E, Institute of Electrical and Electronics Engineers standards, National Electrical Testing Association standards, National Electrical Safety Code, and Uptime Institute standards.
Ability to read, interpret, and redline electrical drawings, one-line diagrams, three-line diagrams, control schematics, and sequences of operations, and update as-built models after commissioning.
Experience coordinating with multidisciplinary teams, contractors, and vendors in construction environments.
Ability to work safely in industrial construction environments and follow lockout/tagout, National Fire Protection Association, Occupational Safety and Health Administration, and SpaceXSI safety protocols.
Commissioning experience that includes functional performance testing, pre-functional testing, site acceptance testing, load-bank testing, protection-relay testing, integrated system testing, and system turnover.
Data center systems experience and prior work on mission-critical projects.
Hands-on experience with electrical power monitoring systems, building management systems, building automation systems, and power-system controls troubleshooting and integration, including Modbus and BACnet.
Knowledge of refrigerant systems, direct liquid cooling, and advanced heat rejection technologies.
Current Occupational Safety and Health Administration 30 certification or equivalent.
Proficiency with commissioning management platforms such as CxPro, Procore, PlanGrid, or similar tools.
Experience implementing integrated systems testing, owner’s project requirements verification, and feeding as-built data back into the sitewide power model for load flow, short-circuit, coordination, and arc-flash studies.

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 making life multiplanetary and expanding consciousness to the stars.

SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.
