Core Responsibilities

Primary Functions

Operate and maintain high-pressure boilers, centrifugal chillers, cooling towers, and associated auxiliary equipment to supply steam, hot water, and conditioned air for the entire facility.
Conduct regular, systematic rounds and inspections of the central heating plant, meticulously recording key operational data from gauges, meters, and control systems to ensure performance is within designated parameters.
Monitor and precisely adjust system controls, including burners, fuel feed rates, and water levels, to maintain safe, stable, and efficient boiler operation in accordance with established standard operating procedures.
Perform routine and emergency water quality tests on boiler water, condensate returns, and feedwater, and administer prescribed chemical treatments to prevent corrosion, scale, and biological fouling.
Execute a comprehensive preventive maintenance program on all heating plant equipment, including pumps, valves, compressors, and heat exchangers, to minimize unscheduled downtime and extend equipment lifecycle.
Respond promptly and decisively to system alarms and operational abnormalities, employing advanced troubleshooting techniques to diagnose mechanical and electrical faults and implement immediate corrective actions.
Perform formal start-up and shutdown procedures for boilers and related plant systems in a safe, sequential, and well-documented manner, adhering strictly to operational checklists and safety protocols.
Maintain detailed and accurate operational logs, maintenance work orders, chemical treatment reports, and regulatory compliance documentation for auditing and historical analysis.
Skillfully clean, lubricate, and repair plant machinery and equipment, performing hands-on tasks such as repacking valves, replacing mechanical seals, aligning pump motors, and overhauling components.
Monitor and manage the inventory and consumption of fuel oil, natural gas, and treatment chemicals, ensuring an adequate and uninterrupted supply to meet facility demands.
Ensure all critical safety devices, such as pressure relief valves, low-water cutoffs, flame scanners, and interlocks, are functioning correctly through regular testing, calibration, and inspection.
Isolate and de-energize equipment using formal lock-out/tag-out (LOTO) procedures before commencing any maintenance or repair activities to guarantee personnel safety.
Oversee the operation of the building automation system (BAS) or energy management system (EMS) to monitor, trend, and control HVAC and heating parameters throughout the campus or facility.
Read and interpret complex technical manuals, engineering blueprints, and piping and instrumentation diagrams (P&IDs) to understand equipment functionality and facilitate effective troubleshooting.
Perform minor pipefitting and plumbing repairs within the central plant to address leaks and maintain system integrity.

Secondary Functions

Maintain a clean, organized, and safe work environment within the boiler room, mechanical spaces, and workshops, adhering to all OSHA and facility-specific safety regulations.
Assist in ordering and maintaining an adequate inventory of spare parts, consumable supplies, and specialized tools required for plant operation and maintenance activities.
Provide technical support and operational guidance to other facilities maintenance staff regarding issues related to the central heating, cooling, and utility distribution systems.
Participate actively in mandatory safety training sessions, emergency response drills, and continuous professional development programs to stay current with industry best practices and evolving regulations.
Escort and monitor outside service contractors performing specialized work on plant systems, ensuring their compliance with facility safety protocols and operational standards.
Operate and perform routine tests on emergency power generation systems to ensure the facility's readiness and resilience in the event of a primary power outage.
Generate periodic reports on key performance indicators such as energy consumption, equipment uptime, and maintenance activities for review by the Facilities Management team.
Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
