• Coordinate with commissioning teams to support system readiness, integrated systems testing (IST), and turnover. 

• Ensure deficiencies are identified early and resolved prior to commissioning milestones. 

Nonconformance & Corrective Action Management 

• Identify, document, and track mechanical nonconformances (NCRs) through closure. 

• Coordinate corrective actions with subcontractors and verify satisfactory resolution. 

• Analyze trends in defects and recommend corrective or preventive measures. 

Trade & Cross-Discipline Coordination 

• Work closely with mechanical subcontractors to communicate quality expectations and resolve field issues. 

• Coordinate with Electrical, Fire Protection, Structural, and Architectural teams to ensure proper system interfaces. 

• Collaborate with Safety, Commissioning, and VDC/BIM teams to support coordinated system delivery. 

Documentation & Reporting 

• Maintain accurate mechanical quality records, including: 

• Inspection and Test Plans (ITPs) 

• Inspection reports and test documentation 

• Deficiency logs and corrective action tracking 

• Utilize project management platforms such as Procore, BIM 360, and Bluebeam. 

• Provide regular quality status updates to the QA/QC Manager and project leadership. 

Project Closeout & Turnover 

• Support preparation of mechanical closeout documentation, including O&M manuals and test records. 

• Verify mechanical systems meet quality and documentation requirements prior to owner turnover. 

• Assist with final inspections and turnover readiness reviews. 

Additional Responsibilities 

• Perform other duties as assigned by the QA/QC Manager or Project Leadership. 

Core Competencies & Behavioral Expectations 

• Quality Mindset: Uncompromising focus on mechanical system quality and reliability. 

• Communication: Clear, direct communication with field teams, subcontractors, and leadership. 

• Problem Solving: Proactively identifies and resolves quality and installation issues. 

• Accountability: Takes ownership of assigned systems and quality outcomes. 

• Organization: Manages multiple systems, inspections, and documentation requirements effectively. 

• Professionalism: Represents the company and project standards with integrity. 

Required & Preferred Qualifications 

• Bachelor’s degree in Mechanical Engineering, Construction Management, or related field preferred. 

• 5–7+ years of experience in mechanical QA/QC, field engineering, or MEP construction. 

• Experience on mission-critical or hyperscale data center projects strongly preferred. 

• Strong working knowledge of mechanical codes and standards, including ASHRAE, NFPA, IMC, SMACNA, and applicable local codes. 

• Familiarity with hyperscale owner standards  

• Proficiency with Microsoft Office and construction management software (Procore, BIM 360, Bluebeam). 

• Strong written and verbal communication skills. 

Physical Requirements & Work Environment 

• Ability to work on-site in an active construction environment for extended periods. 

• Frequent walking, standing, climbing stairs/ladders, and field inspections.
