Data Center MEP Engineer: Mechanical & Plumbing

United States Digital Space LLC; Starbase (TX); On-site; USD 110,000 - 170,000; Full time

Job summary

United States Digital Space LLC is seeking a Mechanical Engineer with deep mechanical and plumbing expertise to design, specify, and commission cooling and fluid systems for data center infrastructure. This role blends critical facilities engineering with hands-on startup in mechanical rooms.

Responsibilities include designing chilled water plants, plumbing systems, and advanced liquid cooling tech, plus leading commissioning and vendor coordination.

Qualifications

• Bachelor's degree in Mechanical Engineering or related discipline.
• 5+ years of experience in mechanical/plumbing design for mission-critical facilities, data centers, or comparable industrial environments.
• Experience with HVAC and hydronic system design and code compliance.

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.
