Chemical Service Technician for Data Centers

Garratt Callahan Co•Reno, NV

78d•$85,000 - $100,000•Onsite

About The Position

Oversee the chemical cleaning, passivation, and flushing of primary cooling loops during the construction phase of large-scale data centers. Perform on-site technical lead role, coordinating with mechanical contractors to ensure water chemistry meets stringent, time-sensitive specifications and managing the logistics and documentation for each project in a Google document workflow (Google Workspace).

Requirements

Two of the following: Water Chemistry Basics (Proficiency in performing and documenting field water analysis - e.g., glycol %, pH, conductivity, iron, phosphate, and inhibitor levels), Project Coordination (Experience or ability to manage project timelines, including the logistics of ordering chemicals and coordinating deliveries with freight carriers and Garratt-Callahan Orderdesk / Commodity Manager), Direct experience (Chemical cleaning of closed-loop HVAC systems), Industrial water Experience (Minimum 2–3 years of experience in industrial water treatment), Mechanical Contractor Experience (Commissioning or chemical cleaning of closed-loop HVAC systems)
Able to professionally interface with Clients, Mechanical Contractors, and General Contractors to drive the flushing schedule.

Nice To Haves

Ability to read and interpret P&IDs (Piping and Instrumentation Diagrams) and mechanical blueprints to identify isolation valves, bypasses, and system volumes.
Bluebeam experience
Strong ability to perform volume calculations and chemical dosage rates (e.g., calculating the amount of cleaner needed for a 50,000-gallon loop). Basic ratios.
Previous experience working on Hyperscale or Enterprise data center build-outs (e.g., AWS, Meta, Google, or Microsoft sites).
Current OSHA 10 or OSHA 30 Construction Safety certification.
Experience installing and programming water treatment controllers (e.g., Walchem, Advantage, Google Workspace, WebMaster).
Association of Water Technologies (AWT) certifications or a Certified Water Technologist (CWT) designation.
Experience using inventory management software or specialized ERP systems to track orders and shipments.
Familiarity with high-flow filtration skids and temporary bypass pumping setups.

Responsibilities

In-plant passivation of stainless steel
Lead the chemical cleaning and "pre-operational" flushing of closed-loop chilled water systems.
Perform on-site water chemistry testing (e.g., pH, conductivity, iron levels, azole concentrations) to verify system readiness.
Work side-by-side with mechanical contractors to manage roadblocks, pump setups, dose chemistry, and filtration.
Ensure all chemical feed equipment and monitoring controllers are properly installed and calibrated.
Perform service by checking residuals, swapping out filtration, and dosing any necessary chemicals. Write a service report at the end of each service.
Forecast chemical volumes required for system volumes and place timely orders to avoid site delays.
Join weekly project meetings
Track shipments and coordinate the delivery of bulk chemicals or IBC totes to active construction sites.
Maintain precise "Daily Field Reports" and final documentation for the client (Owner's Rep) and/or mechanical contractors.
Align chemical treatment phases with the mechanical construction schedule to ensure on-time commissioning and product delivery.
