We are seeking an experienced and detail‑oriented Commissioning Pipefitter with a strong background in commercial mechanical rough‑ins to support the start‑up and commissioning of large‑scale HVAC and mechanical systems.

The role plays a key part in ensuring piping systems are correctly installed, tested, and fully operational in alignment with project specifications, safety standards, and commissioning protocols.

• Review and interpret piping schematics, isometric drawings, and shop drawings to verify system installation and troubleshoot discrepancies.
• Work closely with commissioning teams, project managers, controls contractors, and field installers to ensure all systems function properly and meet turnover criteria.
• Complete and maintain commissioning checklists and field reports on a company iPad with accuracy and attention to detail.
• Provide input during system walk‑downs and punch lists, ensuring all deficiencies are corrected.
• Maintain a strong focus on jobsite safety, quality, and productivity.

• Minimum 5 years of commercial/industrial pipe fitting experience, with a focus on HVAC and mechanical system rough‑ins.
• Strong working knowledge of piping materials and installation methods, including welded, brazed, threaded, grooved, and press‑fit systems.
• Familiarity with commissioning processes, piping system operation, and functional testing.
• Ability to read and interpret mechanical drawings, riser diagrams, and specifications.
• Experience working on active commercial construction sites and coordinating with multiple trades.
• Availability to work nights, weekends, overtime, and occasional overnight travel as required by project schedules.
• Clean and valid driver’s license.
• Previous experience supporting or performing commissioning/start‑up of HVAC/mechanical systems.
• Understanding of system sequences of operation and controls integration.
• NCCER certification or equivalent trade training a plus.
• Familiarity with ASME and SMACNA standards.

• High school diploma or GED equivalent required.
• OSHA 10 required, OSHA 30 certification preferred.
• Experience with BAS/BMS systems and control startup.

• Climbing up and down ladders.
• Push, pull, and frequently carry objects as tools, materials and equipment weighing up to 50 pounds.
• Stoop, kneel, crouch and crawl.
• Stand and walk for long periods of time.
• See and hear well with or without correction to avoid safety hazards to themselves and others.
