Senior Data Center MEP Engineer — Cooling & Plumbing Lead

Future Ventures; Town of Texas (WI); On-site; USD 140,000 - 210,000; Full time

Job summary

SpaceX is seeking an experienced Sr. Mechanical Engineer (Data Center MEP Systems) to design and commission cooling and fluid systems for critical data center infrastructure.

You will specify chilled water plants, CRAH/CRAC units, piping for cooling systems, and direct-to-chip/liquid cooling technologies. You will perform heat load calculations, model airflow, size pumps, review drawings with cross-disciplinary teams, and coordinate with vendors for testing and startup activities.

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.

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, IST, and level 5 commissioning for critical cooling infrastructure.
• Work directly 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.
