The Process / Exhaust / Dry Mechanical Commissioning Engineer is responsible for building and planning the commissioning activities for process mechanical, exhaust, and dry utility systems on mission-critical 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.

Responsibilities:

• Review design documents, specifications, P&IDs, isometrics, equipment submittals, and control narratives to build the commissioning database. 
• Lead and execute commissioning activities for process mechanical, exhaust, and dry utility systems for client handover pre-functional checks through system startup, functional testing, and turnover.
• Develop and review commissioning plans, procedures, checklists for: 
• Process Exhaust Systems (General, Acid, Solvent, Toxic)
• Scrubbers, Abatement Systems, and Exhaust Fans
• Dry Mechanical Utilities (CDA, Nitrogen, Vacuum, Process Interfaces)
• Ductwork, dampers, valves, and exhaust control devices
• Perform field walkdowns and verification inspections to confirm installation completeness, cleanliness, labeling, and safety compliance.
• Coordinate and support equipment startup with the trades and vendors. 
• Track, document, and manage commissioning issues, deficiencies, and punch list items, ensuring 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, particularly 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.

Skills Required:

• Strong knowledge of process mechanical, exhaust, and dry utility systems in semiconductor and mission-critical environments.
• Hands-on commissioning experience with: 
• Process Exhaust and Abatement Systems
• CDA, Nitrogen, and Vacuum Systems
• Exhaust Fans, Dampers, and Control Devices
• Scrubbers and Hazardous Exhaust Streams
• Understanding of airflow dynamics, pressure control, redundancy, and exhaust safety principles.
• Ability to read and interpret P&IDs, isometrics, control diagrams, and specifications.
• Familiarity with controls integration, sensors, actuators, and BAS/BMS interfaces.
• Knowledge of applicable codes and standards, including SEMI, ASHRAE, ASME, SMACNA, NFPA, and local AHJ requirements.
• Strong troubleshooting, documentation, and communication skills.
• Comfortable working in active construction and commissioning environments.
• Experience working in cleanroom or high-purity environments strongly preferred.

Education / Licenses / Certifications

• Bachelor’s degree in Mechanical Engineering, Process Engineering, or related technical discipline preferred.
• Equivalent industry experience may be considered in lieu of a degree.
• 3+ years of experience in mechanical commissioning, startup, or systems testing within semiconductor fabs, data centers, or industrial facilities.
• Relevant certifications are a plus:
  • OSHA 10/30
  • SEMI or client-specific safety certifications
  • Commissioning or mechanical trade certifications
• Proof of education, licenses, and certifications will be required where applicable

Benefits:
