About the role
The HPC Mechanical Manager oversees the Central Utility Plant (CUP) at a hyperscale AI/ML data center in West Texas. This role is responsible for ensuring the safe, continuous operation of all thermal, water, and mechanical systems enabling high-density GPU compute.
Responsibilities
- Own end-to-end CUP operation targeting 99.999% availability of cooling, water, and thermal services
- Operate, monitor, and optimize chillers, pumps, cooling towers, dry coolers, heat exchangers, CDUs, hydronic distribution, and expansion systems
- Oversee demineralized water treatment; ensure ultrapure make-up water quality for DLC loops, secondary cooling, closed-loop circuits, and buffer tanks
- Support liquid-cooled HPC (CDUs, manifolds, filtration, leak detection) and air-cooled data halls (CRAH/CRAC, AHUs, humidity and temperature control)
- Operate BMS/SCADA/PLC systems; interpret alarms, trend performance, and adjust setpoints within approved operating envelopes
- Control chemistry for chilled water, condenser water, glycol/hydronic loops, and DLC circuits; manage scaling, corrosion, fouling, and biological risk
- Oversee safe handling and storage of bulk chemicals (acids, caustics, biocides); ensure HSE and spill prevention compliance
- Act as site authority for environmental incidents, near misses, RCAs, and corrective action closure
- Lead Control Room and Field Operations: alarm management, trend-based fault detection, and rapid response to abnormal conditions and thermal excursions
- Execute EOPs during plant upsets; communicate status and recovery actions to stakeholders; coordinate during maintenance windows and commissioning
- Maintain accurate operating logs, shift turnover documentation, incident reports, and work orders
- Safe Work & Change Management: govern Permit-to-Work and LOTO; enforce procedural discipline and exercise stop-work authority
- Champion a “safety first, always” culture
- Own MOPs/SOPs/EOPs — draft, validate during execution, and incorporate lessons learned
- Coordinate with maintenance and engineering teams for safe return-to-service without impact to live loads
- Lead People Leadership: Lead a multi-disciplinary CUP team: Power/Stationary Engineers, Control Room Operators, and Field Technicians
- Manage 24x7 shift coverage, staffing, overtime, and on-call rotations
- Conduct performance management, coaching, and development; drive training in DLC cooling, water chemistry, and emergency operations
- Lead recurring drills: alarm response, thermal excursion, and leak events
- Reliability & Continuous Improvement: Track KPIs: utility availability, chemistry compliance, incident metrics, PM completion, backlog health, and energy/water performance
- Drive corrective actions and optimization of plant efficiency, WUE, and thermal performance
- Own Tier III/IV design intent compliance and regulatory readiness
Qualifications
- Valid 2nd Class Power Engineering License (or ability to obtain/maintain per site authority)
- 5+ years operating mission-critical or industrial utility systems with progressive leadership responsibility
- Strong CUP fundamentals: chillers, hydronic/glycol loops, pumps, heat exchangers, VFDs, mechanical refrigeration
- Hands-on experience with HPC liquid cooling (CDUs, manifolds, filtration, leak detection)
- Ability to read one-lines, P&IDs, and MEP drawings; proficient with BMS/SCADA/PLC systems
- Proven ability to lead teams in high-availability, high-consequence environments
- Must lift 50 lbs., climb ladders, work in varied environments; on-call rotation required
Preferred Qualifications
- Boilers, steam systems, large-frame gas or steam turbines; hyperscale data center or heavy industrial background
- EPA 608 Universal; OSHA 10/30; NFPA 70E; cooling tower water treatment certification
- CMMS proficiency; hydronic balancing and data center thermal operations experience
Pay
The salary range will start at $145,000. Actual compensation will be determined based on factors such as experience, qualifications.
