Utilities Maintenance Technician

Amentum is seeking 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 in Groton, CT. This role is essential to ensuring the reliable, safe, and efficient operation of the central power plant and utility systems that directly enable pharmaceutical manufacturing, laboratory, and research activities.

The Utilities Maintenance Technician serves as a subject matter expert responsible for responding to work orders, performing in-depth troubleshooting, root cause analysis, and delivering proactive, predictive, preventive, and corrective maintenance on high-pressure boilers, steam turbines, industrial chillers (electric and absorption), boiler feedwater systems, cooling towers, compressed air/gas systems, vacuum systems, heat exchangers, pumps, valves, steam distribution networks, and all associated support equipment. All work is performed in a highly regulated cGMP pharmaceutical manufacturing environment with strict adherence to safety, quality, environmental, and operational standards.

Key Responsibilities

Maintenance Execution & Technical Expertise

• 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.

• 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.

Compliance, Safety, Documentation & Quality

• 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.

Continuous Improvement, Reliability & Team Support

• 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.
