Senior Data Center MEP Systems Engineer

InvestedintheMission; Town of Texas (WI); On-site; USD 140,000 - 190,000; Full time

Job summary

SpaceX is seeking a Sr. Mechanical Engineer (Data Center MEP Systems) to design, specify, and commission cooling and fluid systems for our critical facilities.

You’ll own mechanical/plumbing design from concept through startup, interfacing with architects, electrical, and controls teams. The role requires 10+ years in mechanical/plumbing design for mission-critical environments, with hands-on experience in chilled water, CRAH/CRAC, piping, and direct liquid cooling.

Qualifications

• Bachelor’s degree in Mechanical Engineering or related discipline.
• 10+ years of experience in mechanical/plumbing design for mission-critical facilities, data centres, or comparable environments.
• Experience with liquid cooling technologies (direct-to-chip, rear-door heat exchangers, immersion cooling).
• Familiarity with Uptime Institute Tier standards and ASHRAE data centre thermal guidelines.

Responsibilities

• Design and specify mechanical cooling systems for data center facilities: chilled water plants, CRAH/CRAC units, air handling units, 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 modelling, 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, IST, and level 5 commissioning for critical cooling infrastructure.
• Work with equipment vendors 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.
