Mechanical Engineer

GTN Technical Staffing; Dallas (TX); On-site; USD 120,000 - 180,000; Full time

Job summary

GTN Staffing is seeking a Mechanical Engineer to design and commission piping and fluid distribution systems for AI, HPC, and data center infrastructure. Own engineering from hydraulic calculations through installation coordination, testing, and commissioning of chilled water, glycol, and cooling loops with chiller plants.

PE licensed with 7-10+ years of experience, preferably in data centers, is required. Experience with CAESAR II/AutoPIPE and BIM/Revit is essential for coordinating large-bore

Qualifications

• Bachelor's degree in Mechanical Engineering from an ABET-accredited program or equivalent.
• Professional Engineer (PE) license.
• 7-10+ years of mechanical engineering experience, including hands-on chilled-water or process piping design.
• Proficiency with CAESAR II, AutoPIPE, or comparable pipe stress analysis software.
• Working knowledge of ASME B31.3 and B31.9.
• Experience with hydraulic calculations, thermal expansion, material compatibility, and failure-isolation design.
• Experience coordinating BIM layouts and developing pressure-testing and flushing procedures.
• Experience verifying valve and pump operation during commissioning.

Responsibilities

• Perform hydraulic modeling, pipe sizing, pressure-drop calculations, friction-loss analysis, and NPSH assessments.
• Evaluate pipe stress and thermal expansion using CAESAR II, AutoPIPE, or equivalent software; design supports, anchors, expansion loops, and joints.
• Design cooling loops and integrate Coolant Distribution Units (CDUs) with facility and rack-level cooling systems.
• Specify piping materials, seals, filtration, and water-treatment requirements to address corrosion, contamination, and fluid compatibility.
• Coordinate large-bore piping layouts in BIM/Revit, resolving structural and electrical clashes.
• Design isolation arrangements, including double block and bleed, to maintain cooling availability under N+1 or 2N requirements.
• Develop and witness pressure testing, flushing, and cleanliness procedures.
• Verify valve, pump VFD, and system response during Level 4/5 commissioning.
• Serve as Engineer of Record, review vendor submittals, prepare technical specifications, and provide commissioning sign-off.

Job description

GTN Staffing is currently hiring for a Mechanical Engineer - Process Piping & Liquid Cooling*

GTN Technical Staffing is seeking a Mechanical Engineer to design and commission piping and fluid distribution systems supporting AI, high-performance computing, and data center infrastructure. This is an opportunity to own engineering from hydraulic calculations and pipe stress analysis through installation coordination, testing, and commissioning. Systems include chilled water, condenser water, glycol, and technology cooling loops connected to electric and absorption chiller plants.

PE licensure is required. Engineers with relevant process-industry experience are encouraged to apply; prior data center experience is preferred.

What You’ll Do-

• Perform hydraulic modeling, pipe sizing, pressure-drop calculations, friction-loss analysis, and NPSH assessments.
• Evaluate pipe stress and thermal expansion using CAESAR II, AutoPIPE, or equivalent software; design supports, anchors, expansion loops, and joints.
• Design cooling loops and integrate Coolant Distribution Units (CDUs) with facility and rack-level cooling systems.
• Specify piping materials, seals, filtration, and water-treatment requirements to address corrosion, contamination, and fluid compatibility.
• Coordinate large-bore piping layouts in BIM/Revit, resolving structural and electrical clashes.
• Design isolation arrangements, including double block and bleed, to maintain cooling availability under N+1 or 2N requirements.
• Develop and witness pressure testing, flushing, and cleanliness procedures.
• Verify valve, pump VFD, and system response during Level 4/5 commissioning.
• Serve as Engineer of Record, review vendor submittals, prepare technical specifications, and provide commissioning sign-off.

What You’ll Bring-

• Bachelor’s degree in Mechanical Engineering from an ABET-accredited program or equivalent.
• Professional Engineer (PE) license supporting Engineer of Record responsibilities.
• 7-10+ years of mechanical engineering experience, including hands-on chilled-water or process piping design.
• Proficiency with CAESAR II, AutoPIPE, or comparable pipe stress analysis software.
• Working knowledge of ASME B31.3 and B31.9.
• Experience with hydraulic calculations, thermal expansion, material compatibility, and failure-isolation design.
• Experience coordinating BIM layouts and developing pressure-testing and flushing procedures.
• Experience verifying valve and pump operation during functional commissioning.
• Strong troubleshooting, documentation, and coordination skills.

Preferred Experience:

• Comparable process-industry or mission-critical facility experience.
• Absorption chilling systems and lithium bromide handling.
• Master’s degree in Mechanical Engineering, Fluid/Thermal Engineering, or a related field.
