• 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.

• Occasional lifting of materials or equipment up to 20 pounds.

• Exposure to noise, dust, weather, and typical jobsite conditions.

• Ability to review drawings, schedules, and digital documentation regularly
