Mechanical Engineer, Process & Piping

Mechanical Engineer, Process & Piping

Location: Dallas, TX
Industry: Data Centers | Mission Critical | High-Performance Computing

The Opportunity

A rapidly growing technology infrastructure company is seeking a Mechanical Engineer, Process & Piping to join its Power and Cooling Systems engineering team in Dallas.

This is a highly technical role supporting the design and delivery of large-scale data center campuses and high-performance computing infrastructure, including facilities with on-site power generation and advanced liquid cooling systems.

You will take ownership of the fluid distribution networks supporting critical cooling infrastructure, from hydraulic design and pipe stress analysis through testing and commissioning. The environment combines traditional chilled water systems with increasingly sophisticated technologies such as direct-to-chip liquid cooling, CDUs, absorption chillers, electric chiller plants, glycol systems, and ultra-pure secondary cooling loops.

This is an excellent opportunity for an experienced mechanical or process piping engineer looking to apply process-industry engineering principles to some of the most technically demanding infrastructure being developed today.

Key Responsibilities

• Perform hydraulic modeling, NPSH calculations, pipe sizing, friction-loss analysis, and thermal stress analysis.
• Use Caesar II or AutoPIPE to evaluate piping stress and design expansion loops, joints, anchors, and supports.
• Design chilled water, condenser water, and secondary technology cooling loops, including CDU integration for liquid-cooled AI/HPC environments.
• Engineer piping architectures supporting absorption and electric chiller plants with differing pressure, temperature, and turndown requirements.
• Design side-stream filtration, strainers, and air separation systems to maintain fluid quality and protect sensitive cooling equipment.
• Route large-bore piping within BIM/Revit, coordinating closely with electrical, structural, and controls disciplines.
• Develop isolation, redundancy, and double block and bleed strategies to contain failures while maintaining cooling availability.
• Specify piping materials, seals, and gaskets compatible with treated water, glycol, dielectric fluids, and other cooling media.
• Develop and witness hydrostatic/pneumatic testing and flush-to-clean procedures.
• Support Level 4/5 commissioning, including functional testing of control valves, balancing valves, pumps, and VFDs under simulated operating and failure conditions.
• Serve as an engineering authority for piping design, testing protocols, and commissioning documentation.

What We're Looking For

• BS in Mechanical Engineering from an ABET-accredited program or equivalent.
• Professional Engineer (PE) license required.
• 7-10+ years of mechanical engineering experience involving chilled water or process piping systems.
• Strong hands-on expertise in hydraulic modeling, NPSH calculations, pressure-drop analysis, pipe sizing, and thermal expansion.
• Proficiency with Caesar II and/or AutoPIPE.
• Working knowledge of ASME B31.3 and B31.9.
• Experience designing mission-critical chilled water, process piping, or comparable high-availability fluid systems.
• Experience with data center liquid cooling, direct-to-chip cooling, immersion cooling, or CDU integration is highly desirable.
• Understanding of material compatibility across glycol, treated water, dielectric fluids, and other specialized cooling media.
• Experience developing pressure-testing, flushing, and commissioning procedures.
• Background in hyperscale data centers, mission-critical facilities, semiconductor, industrial/process, energy, or similarly complex environments strongly preferred.

Why This Role?

This position sits at the intersection of process engineering, mission-critical infrastructure, and next-generation computing. Rather than simply sizing mechanical systems by conventional rules of thumb, you will engineer and validate cooling networks where flow, redundancy, fluid compatibility, pressure loss, and commissioning performance directly affect the reliability of large-scale computing infrastructure.

Writing approach: I kept the most differentiating technical requirements, especially PE licensure, Caesar II/AutoPIPE, B31.3/B31.9, hydraulics, CDU/liquid cooling, and L4/L5 commissioning, while removing the company name and specific language that could make the advert unnecessarily identifiable.
