This role is for an experienced and highly skilled Utilities Maintenance Technician to provide advanced technical expertise supporting critical utility infrastructure at a premier pharmaceutical research and development facility. The technician will ensure the reliable, safe, and efficient operation of the central power plant and utility systems that directly enable pharmaceutical manufacturing, laboratory, and research activities. The role involves being a subject matter expert, responding to work orders, performing in-depth troubleshooting, root cause analysis, and delivering proactive, predictive, preventive, and corrective maintenance on various utility systems.
Responsibilities
Diagnose, troubleshoot, and repair complex industrial mechanical systems including high-pressure firetube and water tube boilers, steam and gas turbines with auxiliaries, large electric and absorption chillers, high-pressure centrifugal boiler feedwater pumps, condensate and vacuum pumps, control valves and actuators, pneumatic/hydraulic systems, and related utility plant equipment
Execute predictive maintenance strategies using advanced diagnostic technologies: vibration data collection and analysis, infrared thermography for mechanical/electrical hotspots and refractory assessment, ultrasonic testing for steam traps/leaks/thickness, oil sampling and analysis interpretation, borescope inspections, and laser alignment of rotating equipment
Perform comprehensive preventive maintenance per CMMS schedules: lubrication, filter and strainer changes, bearing and seal replacements, packing and gasket work, belt/chain adjustments, precision alignment, cleaning of heat transfer surfaces, and functional testing of controls and safety devices
Maintain and optimize cooling tower systems: fan drive gearboxes, couplings, blade pitch/balance, fill media and drift eliminator inspection/replacement, basin sediment removal, distribution nozzles, makeup water controls, and vibration monitoring
Service high-pressure steam systems: boiler tune-ups and combustion analysis for efficiency and emissions compliance, steam trap testing/repair/replacement programs, condensate return systems, deaerator maintenance, and support for annual boiler inspections and insurance surveys
Maintain feedwater and pumping systems: high-pressure centrifugal pump overhauls (impellers, wear rings, mechanical seals, bearings), laser alignment, suction/discharge valve work, and coordination of chemical treatment interfaces
Perform maintenance on compressed air and gas systems: reciprocating, rotary screw, and centrifugal compressors; inter/aftercoolers; moisture separators; desiccant and refrigerated dryers; filter banks; pressure regulation; and ultrasonic leak detection/repair
Support heat exchanger maintenance: shell-and-tube cleaning (mechanical/hydroblast/chemical), tube bundle inspection and replacement support, gasket and bolting work, and performance monitoring via approach temperature trending

Tailored applications submitted
Conduct or assist with welding, pipefitting, fabrication, rigging, and heavy equipment handling for repairs, modifications, and equipment change-outs as qualified and authorized
Respond to emergency and urgent work orders with rapid diagnostics and repairs to minimize utility downtime impacting manufacturing operations; provide timely status updates and ETAs to stakeholders
Ensure all maintenance activities comply with applicable codes (ASME, NFPA, OSHA), regulations (EPA, CT DEEP), cGMP requirements, and site standards
Maintain complete, accurate documentation suitable for internal audits, regulatory inspections, and client reviews
Champion safety culture: develop and follow detailed Job Hazard Analyses (JHAs), execute rigorous Lockout/Tagout (LOTO) for all energy sources (electrical, mechanical, thermal, pneumatic, hydraulic), utilize required PPE, and participate in confined space entry, hot work, and fall protection programs
Identify, report, and correct safety or reliability issues proactively; perform independent equipment condition assessments to prevent failures that could affect personnel safety, environmental compliance, or production continuity
Maintain precise CMMS records: create, update, and close work orders with detailed findings, parts consumed, labor hours, failure codes, and corrective actions
Support metrics reporting (PM compliance, backlog, MTTR/MTBF, work order aging)
Support environmental programs through proper refrigerant handling (EPA 608), chemical management, wastewater system coordination, and emissions-related maintenance activities
Analyze equipment performance trends and recommend improvements to maintenance strategies, PM frequencies, spare parts strategies, and equipment upgrades to enhance reliability, reduce costs, and improve energy efficiency (boiler combustion, chiller COP, steam trap management, VFD opportunities)
Lead or participate in Root Cause Analysis (RCA) investigations using structured methodologies (5-Why, fishbone, etc.); develop and implement effective corrective and preventive actions (CAPA) to eliminate recurring issues
Collaborate with engineering, operations, EHS, vendors, and capital project teams on equipment upgrades, new installations, commissioning, and major outage/turnaround planning and execution
Mentor junior technicians and operators; contribute to the development and refinement of SOPs, maintenance procedures, training materials, and knowledge transfer initiatives
Provide exceptional customer service through proactive communication, clear explanations of issues and resolutions, and a solutions-oriented approach to supporting manufacturing and research stakeholders
Work collaboratively in a team environment; be friendly, respectful, empathetic, and professional toward teammates and clients at all times
Value and respect employee authenticity and demonstrate cultural awareness to foster a welcoming, memorable, and respectful workplace
Balance multiple tasks and priorities while maintaining strong attention to detail; demonstrate flexibility when shifting priorities as requested by management
Take ownership to resolve issues independently within scope; escalate appropriately; remain adaptable and solutions-focused under changing conditions
