Senior Cooling SME– Piping Specialist

Primary Location

Fairfield, Ohio, Red Oak, TX, or Phoenix, AZ

Overview

The Senior Cooling SME -Piping Specialist is responsible for the design, technical review, standardization, and execution of mechanical piping systems for Modular Data Center and Liquid Cooling solutions, with primary focus on Technology Cooling Systems (TCS) and Facility Water Systems (FWS) supporting high-density AI/HPC infrastructure.

The position requires strong expertise in data center liquid cooling architecture, hydronic piping and hydraulic design, piping materials/components, fabrication, testing, and commissioning.

The SME will also lead the development and continuous improvement of internal piping specifications, engineering standards, design guidelines, and standardized TCS/FWS solutions.

Key Responsibilities

TCS & FWS Piping / Hydraulic Design


* Lead design and technical review of TCS and FWS piping systems, including supply/return headers, distribution piping, CDU interfaces, heat exchangers, pumps, and rack/row liquid cooling distribution.



* Understand the complete cooling path from facility cooling/FWS through CDU or heat exchanger to TCS and IT equipment.



* Perform/review pipe sizing, flow velocity, pressure drop, pump head, Cv/Kv, flow balancing, system pressure, expansion, air separation, drain/fill, and flushing calculations.



* Develop/review P&IDs, piping one-lines, piping layouts, mechanical schedules, valve schedules, and sequences of operation.



* Address system reliability, redundancy, maintainability, water quality, cleanliness, and commissioning requirements.

Piping Specifications & Design Standards


* Develop, maintain, and continuously improve internal piping specifications and engineering design standards for TCS/FWS applications.



* Establish standardized requirements for:



* Piping materials, pipe schedules, fittings, flanges, and joining methods



* Valves, balancing devices, strainers, hoses, gaskets, and instrumentation



* Pipe sizing, flow velocity, pressure drop, and design pressure



* Pipe supports, anchors, guides, restraints, and thermal expansion



* Welding, inspection, cleaning, flushing, passivation, and pressure/leak testing



* System cleanliness, water quality, corrosion control, and commissioning



* Develop standard TCS/FWS architectures, design rules, typical details, component selection guidelines, and engineering best practices.



* Drive design standardization to improve quality, reliability, manufacturability, scalability, and cost effectiveness across Prefab data center solutions.

Materials, Components & Fabrication


* Specify and evaluate piping materials, including 304/304L and 316/316L stainless steel, carbon steel, and other applicable materials.



* Select/review pumps, heat exchangers, valves, balancing devices, strainers, fittings, flanges, hoses, gaskets, expansion provisions, and instrumentation.



* Evaluate compatibili...
