Senior Data Center MEP Systems Engineer

Spacex; Starbase (TX); On-site; USD 130,000 - 190,000; Full time

Job summary

SpaceX seeks a Senior Mechanical Engineer (Data Center MEP Systems) to design, specify, and commission cooling and fluid systems for our data center infrastructure. You will bridge facilities engineering with the physical plant, reviewing designs and guiding startup in real time.

The role requires deep mechanical and plumbing expertise, experience with direct-to-chip cooling or immersion systems, and ability to coordinate with vendors and cross-functional teams.

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 environments.
• Experience with liquid cooling technologies and data center thermal management.
• Ability to read and produce mechanical/plumbing construction documents, P&IDs, and equipment schedules.
• Familiarity with industry standards and commissioning of critical cooling systems.

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 modeling, and capacity planning to meet design requirements.
• 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: FPT, IST, and level 5 commissioning for critical cooling infrastructure.
• Work with vendors on equipment specs and factory 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 infrastructure.
