Datacenter MEP Field Engineer

Hydra Host•Miami, FL

2d•$80,000 - $120,000•Onsite

About The Position

This role is for a hands-on Field Engineer responsible for liquid cooling and HVAC infrastructure within GPU compute environments. The engineer will manage CDUs, direct-to-chip loops, facility water plants, precision air handling, power distribution, power chain assessment, and power analysis management, particularly at rack densities where miscalculations can lead to hardware downtime.

Requirements

Any Journeyman MEP Trade License or higher.
Experience with liquid cooling 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.

Nice To Haves

Portfolio showcasing designed or delivered projects (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).
Several years of datacenter mechanical/electrical installation and commissioning experience.
Experience with DCIM/BAS integration for cooling monitoring and electrical capacity management.

Responsibilities

Evaluate and commission liquid cooling for GPU compute, including CDUs, direct-to-chip cold plates, rear door HX, immersion tanks, and chilled water plants. Size heat rejection based on real TDP data.
Manage PDU/UPS/XFR/ATS/STS from medium 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, verifying delta-T, flow rate, coolant pressure testing, and refrigerant charge.
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.
