This role plays a critical part in delivering reliable, safe, and fully operational mission-critical infrastructure by performing inspections, coordinating testing activities, validating system performance, and supporting issue resolution throughout construction and commissioning phases.

• Demonstrate strong working knowledge of data center electrical and mechanical systems, including power distribution, UPS, generators, HVAC, cooling systems, controls, and life safety systems.
• Accurately interpret drawings, specifications, submittals, sequences of operation (SOOs), and commissioning plans.
• Identify discrepancies between design documents and field installations and escalate for resolution.

• Perform detailed field inspections to verify installations comply with approved drawings, specifications, manufacturer requirements, and applicable codes (NEC, NFPA, ASHRAE, local AHJ).
• Verify proper installation of equipment, supports, labeling, grounding, clearances, and accessibility.
• Track deficiencies and punch list items, working with construction teams to ensure timely closure.

• Witness and oversee pressure testing, leak testing, flushing, cleaning, megger testing, and equipment start-ups.
• Support and observe Factory Acceptance Tests (FATs), Site Acceptance Tests (SATs), and Functional Performance Testing (FPT).
• Validate operational readiness of systems and ensure testing is executed per approved procedures and commissioning plans.
• Confirm system performance aligns with design intent and redundancy requirements for mission-critical operations.

• Maintain accurate and organized QA/QCx documentation, including inspection reports, test results, deficiency logs, and turnover records.
• Review contractor documentation such as test reports, checklists, and as-built drawings for completeness and accuracy.
• Support systems turnover, client acceptance, and commissioning closeout packages.

• Collaborate with construction teams, commissioning agents, engineers, vendors, and client representatives to resolve quality and commissioning issues.
• Participate in coordination meetings, commissioning readiness reviews, and system walkthroughs.
• Communicate issues clearly and professionally, ensuring alignment across all stakeholders.

• Enforce site safety policies and support compliance with EHS requirements, including LOTO, PPE, and energized work controls.
• Promote quality and commissioning best practices throughout all phases of construction and startup.
• Support continuous improvement by identifying recurring issues and recommending process enhancements.
• Any other duties or responsibilities that may be assigned to you in your role. 

• 7-10 years of experience in data center, mission-critical, or large-scale commercial construction QA/QC or commissioning.
• Strong understanding of electrical and mechanical systems in critical facilities.
• Experience witnessing and documenting testing activities.
• Ability to read and interpret technical drawings, specifications, and test procedures.
• Excellent documentation, communication, and coordination skills.
• Ability to work in a fast-paced construction environment and manage multiple priorities

• Associate’s or Bachelor’s degree in Mechanical Engineering (highly desirable, not required).
• High School Diploma required.
• Trade certifications are an advantage.
• Proof of education, licenses, and certifications will be required where applicable
