About The Position

Praetorian Power Protection, the leader in NETA testing and staff augmentation to the mission critical industry, is seeking a veteran Mechanical Commissioning Superintendent to lead the testing and integration of complex HVAC and cooling systems within mission-critical data center environments. You will be responsible for ensuring that high-density cooling infrastructure—from chilled water plants to liquid cooling systems—is validated, optimized, and ready for 100% uptime.

Requirements

5+ years of experience in mechanical commissioning, HVAC field engineering, or mechanical project management.
Direct experience in Data Center construction or commissioning is mandatory.
Deep technical knowledge of chilled water systems, DX systems, evaporative cooling, and piping infrastructure.
Coordinate the execution of scripts with the Commissioning Authority and associated vendors/subcontractors.
Strong understanding of OSHA standards and Lockout/Tagout (LOTO) procedures for mechanical systems.
Minimum of 5+ years of professional experience in electrical commissioning or electrical construction management.
Proven track record working specifically on Data Center projects or similar mission-critical facilities.
Strong background in low voltage (LV) systems, including fire alarm, security, and controls/monitoring systems.

Nice To Haves

Experience with Liquid Cooling or Rear Door Heat Exchangers (RDHx) in high-density environments.
Certification from ACG, NEBB, or BCxA (CCP).
Proficiency in Bluebeam and commissioning management software (e.g., CxAlloy).
Strong leadership skills with a "boots-on-the-ground" approach to problem-solving.
OSHA 30-Hour Construction Safety certification.
Familiarity with commissioning software platforms (e.g., CxAlloy, Bluebeam, or Procore).
Exceptional communication skills with the ability to translate complex technical issues for non-technical stakeholders.

Responsibilities

Oversee the full commissioning lifecycle (L1–L5), specifically focused on Mechanical, Plumping, and Fire Protection (MPF) systems.
Direct the functional performance testing (FPT) of CRAHs/CRACs, chillers, cooling towers, pumps, and AHUs.
Lead integrated systems testing (IST) using load banks to simulate server heat loads and verify cooling redundancy.
Partner with controls technicians to validate Building Management System (BMS) sequences of operation and alarm notifications.
Analyze P&IDs, sequences of operation, and mechanical specifications to identify potential points of failure before site mobilization.
Manage the mechanical punch list, working closely with mechanical contractors to resolve deficiencies and perform re-testing.
Direct the Level 1 through Level 5 (L1-L5) commissioning process, specifically focusing on the integration of low-voltage systems and critical power infrastructure.
Manage the onsite testing of UPS systems, switchgear, PDU/RPP units, and EPMS/BMS integrations.
Review design drawings, specifications, and submittals to ensure "buildability" and compliance with data center redundancy requirements (N+1, 2N).
Author and execute detailed Commissioning Scripts (Scripts/FPTs) and Final Commissioning Reports.
Maintain rigorous punch-list tracking and resolution.
Enforce strict NFPA 70E standards and electrical safety protocols during energized testing phases.
Act as the primary liaison between the client, MEP contractors, and equipment vendors to maintain the project schedule and resolve technical roadblocks.
