About The Position

XNRGY Climate Systems is seeking an experienced Project Manager – Mission Critical Data Center Programs (HVAC) to lead onsite execution of complex HVAC service and construction programs. This role serves as the on-site face of XNRGY for customers, General Contractors (GCs), and mechanical and electrical trade partners on mission-critical data center projects. The Project Manager owns execution across both air-side equipment—including CRAC/CRAH units, air handling units, and economizers—and chiller/water-side plant equipment, including chillers, cooling towers, pumps, and piping. The Project Manager will lead execution from rework and start-up through commissioning, warranty, and field support, while coordinating building management and controls integration and supporting the uptime-critical requirements of Tier III/IV data center environments. The Project Manager is responsible for driving safe, disciplined execution of highly technical HVAC mechanical programs in active mission-critical construction environments. Working across internal teams, mechanical contractors, controls integrators, GCs, commissioning agents, OEM technicians, and data center operators, this position coordinates equipment start-up, Level 3–5 commissioning, functional performance testing, integrated systems testing (IST), and ongoing field support. The Project Manager will also oversee Superintendents and other onsite staff, represent XNRGY at GC and project meetings, manage project risks and dependencies, and serve as the primary escalation point for HVAC scope, schedule, and change management.

Requirements

10+ years of progressive experience in HVAC service operations or project management, ideally within mission-critical or data center environments.
Proven track record managing complex, highly technical HVAC mechanical programs across both: Air-side systems: CRAC/CRAH units, air handlers, precision cooling, and VRF. Chiller/water-side systems: chillers, cooling towers, condenser water and chilled water piping.
Working knowledge of mechanical drawings and sequences of operation.
Working knowledge of BMS/controls platforms and protocols such as BACnet, Niagara, and Modbus as they relate to HVAC systems.
Experience with ERP/CRM systems, service management platforms, and performance dashboards.
Strong planning and program structuring skills with disciplined follow-through managing complex HVAC field operations at scale in high-stakes, uptime-critical settings.
Balances empathy with sound business judgment while proactively supporting data center client cooling and reliability needs.
Builds trust through clear, professional interaction with GCs, mechanical contractors, customers, and internal teams across all levels of the organization.
Operates with composure under the tight and shifting priorities typical of mission-critical HVAC construction and commissioning environments without compromising execution or safety standards.

Nice To Haves

Direct experience with mission-critical infrastructure—including data centers, hyperscale, colocation, or other uptime-sensitive facilities—strongly preferred.
Mechanical or HVAC engineering background preferred; candidates with strong operational, business, or technical program management experience specifically within HVAC will also be considered.

Responsibilities

Apply project methodologies to drive scalable, repeatable, and cost-effective execution across mission-critical HVAC mechanical programs.
Lead cross-functional internal and external teams—including mechanical contractors, controls integrators, GCs, and commissioning agents—across rework, start-up, commissioning, warranty, and field support.
Lead execution across both air-side equipment and chiller/water-side HVAC systems.
Coordinate Level 3–5 commissioning, including equipment start-up, functional performance testing, and integrated systems testing (IST).
Coordinate OEM technicians and commissioning agents to validate cooling capacity and redundancy design.
Track project progress, risks, and interdependencies related to mechanical equipment delivery, refrigerant piping, ductwork, and controls sequencing against data center construction schedules.
Ensure strict adherence to safety requirements including LOTO, confined space, and hot work, particularly when operating in live or near-live data halls.
Serve as the primary escalation point and strategic liaison with General Contractors, mechanical engineers, and data center operators on HVAC scope, schedule, and change management.
Oversee Superintendents and other onsite staff.
Represent XNRGY at all GC and project meetings.
Maintain regular construction-site presence throughout project execution.
