LotusWorks, Chandler, Arizona, United States, 85249
LotusWorks is an Engineering Services provider specializing in managing Commissioning, Construction Services, Calibration, Operations & Maintenance scopes of work within global manufacturing facilities. LotusWorks operates globally across EMEA and North America partnering with the world's leading manufacturers across the Semiconductor, Pharmaceutical & Biologics, Medical Device and Data Centre sectors. Our team of Engineering and Technical professionals is immersed in cutting-edge technologies and innovations. LotusWorks is committed to a diverse and inclusive workplace, integral to our people-first approach.
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. Education / Licenses / Certifications High School Diploma or equivalent, required. Associate's, Bachelor's degree or technical certificate in a related field preferred but not required. Proof of education, licenses, and certifications will be required where applicable. Benefits: Medical, Dental and Vision Insurance Life, Short-Term, Long-Term Disability Insurance Training and Education Assistance 401k Retirement Plan Extra Annual Leave with Years of Service Maternity/Paternity Leave Recognition Rewards
