About The Position

Hands-on Field Engineer that owns liquid cooling and HVAC infrastructure in GPU compute environments. This role involves managing Cooling Distribution Units (CDUs), direct-to-chip loops, facility water plants, precision air handling, power distribution, power chain assessment, and power analysis management at rack densities where miscalculations can take hardware offline.

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.

Nice To Haves

Portfolio showcasing designed or delivered projects, including CDU install docs, HVAC load calcs, One-Line Power Train diagrams, commissioning reports with thermal data, piping schematics, conduit installations, construction photos, capacity models.
Personal site, portfolio, or reference list of completed facilities.

Responsibilities

Evaluate and commission liquid cooling for GPU compute, including CDUs, direct-to-chip cold plates, reardoor HX, immersion tanks, and chilled water plants.
Size heat rejection from real TDP data.
Manage PDU/UPS/XFR/ATS/STS from Medium Voltage to Low Voltage transformation, inversion, rectification, and power distribution one-lines.
Oversee CRAH/CRAC/CDUs, hot/cold aisle containment, economizers, humidification, and supplemental cooling for mixed air/liquid deployments.
Specify piping for liquid cooling loops, including routing, glycol concentration, pump curves, flow balancing, filtration, expansion tanks, and leak detection.
Perform thermal validation under load, including delta-T, flow rate verification, coolant pressure testing, and refrigerant charge validation.
Coordinate with mechanical subcontractors, vendors, and controls integrators to prevent trade conflicts.
Integrate DCIM/BAS for cooling monitoring and electrical capacity management.
Perform datacenter mechanical/electrical installation and commissioning.
Manage liquid cooling systems at 75+ kW/rack, including CDUs, direct-to-chip, rear-door HX, or immersion.
Ensure N+1/2N redundancy architectures for cooling plants and concurrently maintainable designs.
Travel for site surveys, construction oversight, and commissioning.
