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. In this role, you will provide hands-on mechanical commissioning training and mentorship to engineers and technicians working on mission-critical data center and advanced manufacturing projects. This is a field-based mechanical engineering position focused specifically on mechanical systems, equipment startup, testing, functional testing, and integrated systems testing. You will partner with Commissioning Managers and Leads to develop mechanical commissioning competency across project teams. This position requires approximately 75–90% travel, including extended assignments at project locations. Responsibilities: Travel extensively between mission-critical project locations to provide hands-on mechanical commissioning training and mentorship. Embed with project teams to train and develop junior Mechanical Commissioning Engineers and Technicians during live field commissioning activities. Develop junior personnel from initial field exposure through supervised execution and independent mechanical commissioning competency. Train personnel across the mechanical commissioning lifecycle, including L2 installation verification, L3 startup, L4 functional performance testing, L5 integrated systems testing, and turnover. Provide field training on chillers, cooling towers, air handling units (AHUs), computer room air handlers (CRAHs), computer room air conditioning units (CRACs), pumps, heat exchangers, hydronic systems, HVAC systems, piping systems, valves, controls, and associated mechanical equipment. Teach personnel to interpret mechanical drawings, P&IDs, equipment schedules, sequences of operation, specifications, equipment submittals, control diagrams, and approved settings. Provide practical instruction on mechanical testing, including pressure testing, flushing, equipment startup, pump testing, valve verification, airflow and waterflow verification, temperature and pressure verification, controls testing, and functional testing. Train personnel on mechanical system startup readiness and safe work practices, including LOTO/COHE, equipment isolation, stored energy hazards, PPE, and safe mechanical work practices. Develop troubleshooting competency across mechanical systems, controls, communications, HVAC equipment, piping systems, and associated equipment. Train personnel to identify and document mechanical installation deficiencies, QA/QC issues, commissioning defects, failed test conditions, and system readiness risks. Provide instruction on mechanical commissioning documentation, including test scripts, checklists, deficiency reports, test evidence, commissioning records, and turnover documentation. Coordinate with Commissioning Managers and Leads to identify upcoming mechanical commissioning activities that provide training and development opportunities. Develop individual training plans and conduct field competency assessments to document technical progression and readiness for additional responsibility. Identify recurring mechanical commissioning knowledge gaps and develop targeted training materials using lessons learned, troubleshooting examples, and commissioning best practices. Support consistent mechanical commissioning execution, testing methodology, documentation quality, and technical standards across project locations. Provide technical leadership with feedback on personnel readiness, competency gaps, training…
