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 priorities, and development needs. • Support the development of personnel with the potential to progress into Mechanical Commissioning Engineer, Lead, and SME positions. • Maintain flexibility to travel approximately 75-90%, including short-term visits and multi-week or multi-month project assignments. • Any other duties or responsibilities that may be assigned to you in your role. Skills Required: • Extensive hands-on mechanical commissioning experience within data center, semiconductor, or other mission-critical facilities. • Strong knowledge of mission-critical mechanical systems, including chillers, cooling towers, AHUs, CRAHs/CRACs, pumps, heat exchangers, hydronic systems, HVAC systems, piping systems, valves, controls, and associated mechanical equipment. • Strong understanding of L2-L5 mechanical commissioning, startup, functional performance testing, Integrated Systems Testing (IST), and turnover. • Experience performing or overseeing mechanical testing, troubleshooting, startup, and commissioning of mission-critical mechanical systems. • Ability to read and interpret mechanical drawings, P&IDs, equipment schedules, specifications, sequences of operation, equipment documentation, and control diagrams. • Strong knowledge of mechanical LOTO/COHE, equipment isolation, stored energy hazards, and safe mechanical work practices. • Demonstrated ability to train and mentor Mechanical Commissioning Engineers and Technicians through hands-on field instruction. • Strong communication, leadership, troubleshooting, and problem-solving skills. • Ability and willingness to travel approximately 75-90% to active construction and commissioning project sites. Education / Licenses / Certifications • Bachelor's degree in Mechanical Engineering preferred. • Relevant mechanical trade license or certification preferred. • Commissioning certification preferred. • 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
