Chiller Mechanic

Job Description

On-site in Abilene, TX at the data center

Ideal Candidate Profile

• Experience with mission-critical, industrial, pharmaceutical, semiconductor, healthcare, or large commercial mechanical systems.

• Air-cooled chiller specifics: screw/scroll compressors, condenser fans, VFDs, refrigerant circuits, expansion valves, low-ambient operation, glycol systems, pumps, leaks, alarms, and controls.

• Core data-center operations expectations: perform rounds, respond to alarms/outages, follow SOP/MOP/EOP procedures, use LOTO, complete PMs/work orders, trend BMS data, and document findings/escalations.

• Ability to interpret mechanical drawings, P&IDs, sequences of operation, and equipment documentation.

• Working knowledge of chilled water systems, DX cooling, controls integration, redundancy concepts, and operational risk.

• Technical certification, trade experience, apprenticeship completion, or equivalent practical experience preferred.

• Experience with chillers, pumps, cooling towers, CRAH/CRAC units, heat exchangers, water treatment interfaces, controls, and mechanical distribution systems.

• Familiarity with BMS, PLC/controls concepts, trending, alarm management, commissioning, and vendor coordination.

• Experience supporting maintenance planning, acceptance testing, energy-efficiency projects, or equipment change-outs.

• ASHRAE certifications and training are relevant for growing HVAC depth; ASHRAE currently maintains multiple certifications and identifies the Certified HVAC Designer (CHD) credential as validation of HVAC design competency.

• Schneider Electric University data center power-and-cooling coursework and DCCA-oriented training are relevant for technicians building broader data center fluency.

• OEM or manufacturer training on chillers, CRAH/CRAC systems, cooling towers, controls platforms, or water-cooled plant equipment preferred.

• Uptime Institute's Accredited Tier Designer (ATD) is more design-oriented than technician-oriented, but it is a legitimate data center credential for candidates involved in higher-level infrastructure design and Tier concepts. Skills and Competencies

• Strong troubleshooting and diagnostic capability.

• EPA Section 608 Technician Certification required for roles involving where attaching gauges, recover/add refrigerant and/or refrigerant-handling activities on stationary HVACR equipment.
