About the role

Senior Mechanical Engineer focused on data center MEP systems, designing, specifying, and commissioning cooling and fluid systems for critical facilities at SpaceX data center sites.

Responsibilities

  • Design and specify mechanical cooling systems for data center facilities: chilled water plants, CRAH/CRAC units, air handling units, and cooling towers
  • Own plumbing system design: domestic water, sanitary, storm drainage, makeup water, and process piping for cooling systems
  • Evaluate and specify facility liquid cooling infrastructure (direct-to-chip, rear-door heat exchangers, immersion cooling)
  • Perform heat load calculations, airflow modeling, and capacity planning to ensure design requirements are met
  • Develop piping design, pump sizing, and hydraulic calculations for chilled water and condenser water loops
  • Review and coordinate mechanical/plumbing drawings with architectural, electrical, structural, and fire protection disciplines
  • Support commissioning of mechanical systems: functional performance testing, integrated systems testing (IST), and level 5 commissioning for critical cooling infrastructure
  • Work directly with equipment vendors (chillers, CRAH units, pumps, cooling towers) on technical specifications and factory witness testing
  • Troubleshoot operational issues in existing facilities — water treatment, pump cavitation, control valve failures, capacity shortfalls
  • Support due diligence and technical evaluation for new site selection, including utility water availability and existing mechanical infrastructure condition

Qualifications

  • Bachelor’s degree in Mechanical Engineering or related discipline
  • 10+ years of experience in mechanical/plumbing design for mission-critical facilities, data centers, or comparable industrial environments
