Senior Data Center Operations Engineer

The Senior Data Center Operations Engineer is responsible for leading the daily operation, maintenance, and reliability of mission-critical electrical, mechanical, and cooling infrastructure within a high-density, liquid-cooled AI data center. This position serves as the senior technical resource for the facility, working closely with the Facility Manager to ensure safe, efficient, and reliable operations. The Senior Data Center Operations Engineer will provide technical leadership to the site operations team and serve as the primary technical resource when the Facility Manager is unavailable. Responsibilities include overseeing critical power and cooling systems, managing preventive maintenance activities, leading incident response, coordinating vendors and contractors, and maintaining operational readiness. The position also plays a key role in developing site procedures, technical training, and employee qualification programs as the company expands its data center operations. This is a hands-on critical facilities position focused on mechanical, electrical, and plumbing (MEP) infrastructure rather than IT, networking, or cabling.

Key responsibilities include:

Lead daily operations of mission-critical electrical, mechanical, and cooling systems, including UPS systems, switchgear, power distribution units (PDUs), generators, chillers, computer room air handlers (CRAHs), and liquid cooling infrastructure.

Monitor critical facility equipment and ensure reliable operation of electrical and mechanical systems.

Manage and improve preventive maintenance programs to support equipment reliability and operational readiness.

Maintain facility documentation, maintenance records, and procedures to ensure audit readiness.

Lead incident response activities during equipment failures, outages, and operational escalations.

Make sound technical decisions under pressure to restore service and minimize operational disruptions.

Monitor and optimize facility performance using Building Management Systems (BMS), Computerized Maintenance Management Systems (CMMS), and ticketing platforms.
