Job summary

Submer is seeking an MEP Design Engineer to lead end-to-end MEP design for high-density HPC/AI data centers, including 100-300 MW sites and modular deployments. You’ll coordinate electrical, mechanical, and plumbing systems for scalable, mission-critical facilities and work with NVIDIA GB300 and VR200 reference architectures.

The role demands a strong technical leadership background, experience with liquid cooling, power distribution, and compliance with NEC/NFPA/ASHRAE standards, plus

Qualifications

• Bachelor's degree in Mechanical or Electrical Engineering (or related MEP discipline).
• PE license strongly preferred.

Responsibilities

• Lead the holistic MEP design, specification, and optimization for hyperscale and modular HPC/AI data centers, ensuring integrated performance, reliability, efficiency, and scalability.
• Design electrical systems including MV/LV distribution, switchboards, overhead busways, circuit breakers, transformers, PDUs, grounding, protection, BESS, UPS, and generators.
• Oversee mechanical systems focused on high-density liquid cooling, CRAC/CRAH, heat rejection, airflow management, and redundancy for 100+ kW racks.
• Manage plumbing and fluid systems, including coolant distribution, primary/secondary cooling loops, leak detection, piping, pumps, filtration, and integration with facility water systems or closed-loop designs.
• Architect modular data center solutions (1-2 MW containers/pods) that efficiently aggregate into larger 50-300 MW sites.
• Deliver MEP designs tailored to NVIDIA GB300 (Grace Blackwell) and VR200 (Vera Rubin) reference architectures, addressing rack power and thermal management.
• Perform system-level studies (power, thermal, hydraulic, CFD) and ensure NEC/NFPA/ASHRAE/IEEE compliance.
• Collaborate with architecture, structural, IT, and construction teams through design, procurement, construction, commissioning, handover.
• Optimize for energy efficiency, sustainability, capacity planning, fault tolerance, and total cost of ownership in AI environments.
• Develop standards, create drawings/specifications, troubleshoot issues, and mentor junior MEP engineers.
• Create internal and customer-facing MEP specifications and explain discussions with technical and non-technical customers.
