We are seeking an experienced Mechanical Operations & Maintenance Technician to support the operation, maintenance, and reliability of systems in a mission-critical environment. The ideal candidate will have a strong background in performing preventive and corrective maintenance across a range of mechanical equipment including chillers, cooling towers, and compressors. This role ensures safety, compliance, and consistent system readiness to support client and facility operations.
Responsibilities: • Perform preventive and corrective maintenance on chillers, cooling towers, and compressors in accordance with OEM requirements, internal standards, and best practices. • Execute all scheduled maintenance (quarterly, semi-annual, annual, multi-year) per defined intervals, ensuring proper documentation, coordination, and operational readiness. • Conduct annual chiller PMs during low-load months and ensure all units are fully operable before seasonal demand periods. • Complete semi-annual chiller PMs approximately five to seven months apart from annual PMs to maintain performance and reliability. • Perform quarterly and annual maintenance on cooling towers, including drift eliminator inspections and system condition reporting. • Ensure all inspections are performed and documented within the required timeframes and maintenance windows. • Immediately report any major equipment failures or safety-related findings to site leadership. • Conduct compressor PMs (semi-annual and annual) to maintain reliability and minimize downtime, ensuring only one unit is offline at a time unless otherwise coordinated. • Coordinate system outages and handoffs with operations teams to avoid process or production impacts. • Perform full Lockout/Tagout (LOTO) procedures prior to maintenance, verify zero-energy state, and safely restore systems upon completion. • Execute corrective maintenance as needed, including troubleshooting, parts replacement, and performance verification. • Complete all in-scope repairs such as oil and filter changes, refrigerant filter/dryer replacements, instrumentation calibration, leak repairs, insulation or paint touch-ups, and electrical or mechanical troubleshooting. • For repairs requiring refrigerant removal, obtain approval, provide detailed cost estimates, and perform work only after authorization. • Follow all EPA and environmental compliance standards for refrigerant handling, recovery, and documentation. • Ensure all refrigerant boundary repairs are leak-tested and verified prior to system restart. • Properly contain and dispose of oil, filters, and waste materials to prevent environmental or system alarms. • Use OEM-specified materials and components unless otherwise approved. • Maintain a spare parts inventory of critical items (e.g., fan-train components, vibration switches, oil switches, belts, motors) to support rapid response and minimize system downtime. • Support reliability and uptime by performing regular system inspections, trending performance data, and escalating abnormal conditions. • Participate in root cause analysis (RCA) and reliability improvement initiatives for repeated failures. • Document all work activities, labor hours, materials, and as-found/as-left conditions in the CMMS (Maximo, eMaint, SAP PM, or equivalent). • Generate and submit inspection reports, PM closeouts, and cost summaries as required. • Comply with all site safety requirements, including PPE use, elevated work, confined space entry, and environmental controls. • Coordinate closely with team leads, maintenance planners, and engineers to ensure safe and effective execution of all tasks. • Maintain professionalism, cleanliness, and strong communication throughout all maintenance activities. • Participate in technical and safety training to maintain or expand qualifications. • Achieve zero safety incidents, complete all PMs on time, maintain LOTO compliance, and ensure thorough documentation across all assigned systems. • Perform other duties and responsibilities as assigned.
Skills Required: • 2–5 years’ hands-on experience in operations and maintenance within mission-critical or industrial facilities. • Broad technical knowledge of mechanical systems including chillers, cooling towers and compressors. • Ability to troubleshoot, maintain, and escalate issues with equipment and systems effectively. • Knowledge of environmental, health, and safety standards in mission-critical environments. • Strong communication and collaboration skills for working with engineers, vendors, and operations staff. • Attention to detail with accurate documentation and monitoring of system performance. • Ability to remain proactive and responsive in fast-paced, high-stakes environments.
