The role involves defining the mechanical cooling strategy and overseeing the design for data centers, focusing on efficiency and innovative cooling solutions.
Responsibilities
- Lead design and strategy for data center mechanical systems, including air, liquid, and hybrid cooling
- Define and maintain mechanical design standards for high-density air, rear-door heat exchangers, cold-plate, and immersion cooling
- Drive innovation to improve PUE, WUE, and overall energy efficiency
- Own and update basis-of-design, master specifications, drawings, and sequence-of-operations
- Oversee project-specific adaptations with external consultants and ensure quality through design reviews, inspections, and commissioning
- Perform CFD modeling, airflow/capacity planning, and specify critical equipment (chillers, pumps, CRAH/CRAC, dry coolers)
- Advance sustainability initiatives: free cooling, water-side economizers, and waste-heat reuse
- Collaborate with Electrical, Controls, and Construction teams at all design stages
Skills
- B.S. in Mechanical Engineering or equivalent technical discipline
- 7+ years of experience designing mechanical/cooling systems for data centers, with significant exposure to hyperscale or high-performance computing facilities
- Deep technical knowledge of chilled water systems, air-cooled and water-cooled chillers, direct liquid cooling, and heat rejection plant design
- Experience leading or managing a mechanical engineering team and directing external MEP consultants through a full design lifecycle
- Working command of ASHRAE TC 9.9 thermal guidelines, liquid cooling best practices, and relevant mechanical codes (IMC, ASME, NFPA)
- Demonstrated ability to develop and enforce design standards, basis of design documents, and master specifications across a multi-site portfolio
- Willingness to travel to project sites across the US (estimated 20-30%)
- Professional Engineer (PE) license or Chartered Engineer credential
- Direct experience with modular or prefabricated mechanical system design and off-site manufacturing coordination
- Hands-on CFD experience (6SigmaET, Ansys Icepak, Flotherm) and proficiency with Revit/BIM workflows
- Experience with medium-voltage (4.16 kV+) chiller applications and 800VDC power distribution architectures in data centers
- Background in owner/developer-side roles with direct accountability for system performance and reliability
- Familiarity with FM Global requirements for mechanical systems in mission-critical facilities
Benefits
- Medical, Dental, Vision, Commuter and 401K benefits with company matching
