Mechanical Commissioning Engineer

The Dry Mechanical Commissioning Engineer is responsible for planning and executing commissioning activities for process mechanical, exhaust, and dry utility systems in a high-tech semiconductor facility and high technology construction projects. This role works closely with construction, controls, quality, safety, and operations teams to ensure systems are installed, tested, and turned over in accordance with design intent, client standards, and regulatory requirements.

• →Review design documents, specifications, P&IDs, isometrics, equipment submittals, and control narratives to build the commissioning database.
• →Lead and manage commissioning activities for process mechanical, exhaust, and dry utility systems from pre functional checks through system startup, functional testing, and turnover.
• →Develop and review commissioning plans, procedures, and checklists for:
• →Process Piping Systems (Oil Free Air, Process Cooling Water)
• →HVAC Systems (Exhaust, Supply Air, Hydronic Piping)
• →Industrial Wastewater / Ultra Pure Water Systems
• →Automated valves, dampers, and control devices
• →Perform field walkdowns and verification inspections to confirm installation completeness, cleanliness, labeling, and safety compliance.
• →Coordinate and support equipment startup with trades and vendors.
• →Track, document, and manage commissioning issues, deficiencies, and punch list items to ensure timely resolution.
• →Maintain accurate commissioning documentation, including test results, redlines, as built verification, and turnover packages.
• →Participate in startup readiness reviews, cutover planning, and transition to operations.
• →Enforce EHS, LOTO, and safe commissioning practices, especially when working with hazardous exhaust systems.
• →Provide commissioning status updates and technical input during client and project meetings.
• →Any other duties or responsibilities that may be assigned to you in your role.

• 3+ years of experience in mechanical commissioning, startup, or systems testing within semiconductor fabs, data centers, or industrial facilities.
• Strong knowledge of process mechanical systems, HVAC, and system integration in semiconductor or mission critical environments.
• Understanding of airflow dynamics, pressure control, redundancy, and exhaust safety principles.
• Ability to read and interpret P&IDs, isometrics, control diagrams, BIM models, and specifications.
• Familiarity with controls integration, sensors, actuators, and FMCS/BMS interfaces.
• Strong troubleshooting, documentation, and communication skills.
• Comfortable working in active construction and commissioning environments.
• Experience working in cleanroom or high purity environments.

• Bachelor's degree in Mechanical Engineering/Facilities Engineering, Process Engineering is strongly preferred, but not required
• Proof of education, licenses, and certifications will be required where applicable.
