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

Key Responsibilities
Support and improve mechanical and HVAC architectures and designs for high-availability environments, including chilled water, DX, airside systems, and redundancy strategies.
- Operate, inspect, troubleshoot, and maintain air-cooled chillers and associated mechanical systems in a 24/7 mission-critical environment.
- Diagnose failures involving compressors, fans, VFDs, refrigerant circuits, controls, pumps, valves, and BMS alarms.
- Execute preventive and corrective maintenance, equipment change-outs, and emergency response under approved procedures.
- Support incident response and root-cause analysis; document corrective actions and recommend reliability improvements.
- Coordinate and oversee OEM/vendor work while ensuring safe work controls, LOTO, and operational-risk mitigation.
Perform troubleshooting activities, incident investigations, and root cause analysis for mechanical and HVAC equipment or system issues.
Support capacity planning, retrofits, and operational initiatives, ensuring operability and maintainability of installed systems.
Partner with site operations teams to improve maintainability, safe execution of work, and documentation quality for mechanical and HVAC systems.
Support vendor technical reviews, commissioning activities, and operational handover requirements.
Coordinate with internal teams and external stakeholders to improve performance, consistency, and lifecycle outcomes across sites.
