Commissioning Engineer

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.

ABOUT THE ROLE:

We are seeking an Electrical Commissioning Engineer to execute the buildout, startup, and handover of electrical systems for SpaceXSI's high-performance data centers. This is a hands-on role where you will commission, test, troubleshoot, and turn over critical systems that support next-generation AI supercomputing infrastructure.

You will work closely with construction, engineering, operations, EPC contractors, and OEM vendors to deliver safe, reliable, and high-quality electrical systems. This is a full-time, onsite role with travel to SpaceXSI data center construction sites across the United States.

RESPONSIBILITIES:

• Execute all electrical commissioning activities for MV/LV switchgear, generators, UPS systems, PDUs, ATS/STS, 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 EPC contractors, OEM vendors, design engineers, and SpaceXSI stakeholders for system energization, startup sequences, and integrated system validation.
• Champion safety by enforcing strict adherence to LOTO, NFPA, OSHA, and SpaceXSI safety protocols; participate in daily safety briefings and job hazard analyses.
• Maintain comprehensive as-built documentation, test records, issue logs, and final commissioning reports.
• Support and deliver training programs for operations and maintenance teams on commissioned systems.
