Datacenter MEP Field Engineer

Role Overview

• Evaluate and commission liquid cooling for GPU compute—CDUs, direct-to-chip cold plates, reardoor HX, immersion tanks, and chilled water plants.
• Size heat rejection from real TDP data, not marketing sheets.
• PDU/UPS/XFR/ATS/STS Medium Voltage to Low Voltage transformation, inversion, rectification, power distribution one-lines.
• CRAH/CRAC/CDUs, hot/cold aisle containment, economizers, humidification, and supplemental cooling for mixed air/liquid deployments.
• Spec piping for liquid cooling loops—routing, glycol concentration, pump curves, flow balancing, filtration, expansion tanks, and leak detection.
• Thermal validation under load—delta-T, flow rate verification, coolant pressure testing, refrigerant charge validation.
• Coordinate with mechanical subs, vendors, and controls integrators. Catch trade conflicts before they become change orders.

Requirements

• Any Journeyman MEP Trade License or higher.
• Several years of datacenter mechanical/electrical installation, and commissioning.
• Hands-on liquid cooling experience at 75+ kW/rack—CDUs, direct-to-chip, rear-door HX, or immersion.
• Familiarity with N+1/2N redundancy architectures for cooling plants and concurrently maintainable designs.
• Willing to travel for site surveys, construction oversight, and commissioning.
