Responsibilities

Provide direct supervision to the HVAC lead, Chiller Plant lead, Utilities Maintenance lead, and BMS lead, and through them to the technicians, operators, and specialists in each group.
Establish shift coverage, on-call rotations, overtime plans, and surge staffing for planned outages, seasonal peaks, and emergency events.
Set daily and weekly priorities that balance preventive maintenance, corrective work, projects, and research-driven requests.
Hire, onboard, coach, evaluate, and, when necessary, discipline personnel in accordance with company policy and applicable labor agreements.
Build cross-training so that no single person is the sole source of knowledge for a critical plant or control sequence.
Hold toolbox talks and pre-job briefs covering LOTO, confined space, hot work, elevated work, refrigerant handling, and chemical hazards.
Own day-to-day operating posture of the central chiller plant, including load following, equipment rotation, condenser- and chilled-water temperatures, approach temperatures, and tower performance.
Ensure HVAC systems serving laboratories and controlled environments maintain specified temperature, humidity, air-change, and differential-pressure ranges.
Direct response to environmental excursions, plant trips, loss of redundancy, and utility interruptions; restore service and support quality impact assessments.
Coordinate seasonal changeover, winterization, and peak-load readiness reviews well ahead of weather and occupancy changes.
Own the preventive, predictive, and reliability-centered maintenance program for assigned assets in the site CMMS (Maximo).
Drive completion of PMs on time; investigate chronic backlog and repeat failures; initiate root-cause analysis for significant events.
Specify and oversee vibration analysis, oil analysis, infrared thermography, ultrasonic leak detection, tube inspections, and other PdM methods.
Manage spare-parts strategy for long-lead chiller, tower, AHU, and controls components, including critical-spares min/max levels.
Ensure the BMS is maintained as an operational tool and, where applicable, as a GxP-relevant data source: accurate graphics, validated alarm paths, and reliable historian data.
Establish alarm philosophy: prioritization, deadbands, delay timers, notification paths, and after-hours escalation so operators can act rather than drown in nuisance alarms.
Review trends after excursions and after significant sequence or setpoint changes; document findings.
Operate assigned systems in a manner consistent with cGMP expectations for facilities supporting pharmaceutical R&D, including good documentation practices (GDP).
Ensure refrigerant, pressure-vessel, boiler, backflow, and water-treatment records meet EPA, ASME, and local jurisdictional requirements.
Investigate deviations, environmental monitoring failures, and utility-related quality events; write or contribute to CAPAs that address system and human factors.
Enforce OSHA and site EHS requirements: LOTO, confined space, fall protection, electrical safety awareness, hearing conservation, and chemical handling.
Maintain emergency operating procedures for loss of chilled water, loss of heating, loss of exhaust, smoke event affecting HVAC, refrigerant leak, and flooding of mechanical spaces.
Serve as a primary facilities responder or incident commander-support for utility and HVAC emergencies.
Lead after-action reviews following major outages and incorporate lessons into procedures and training.
