About The Position

M.C. Dean is seeking a Critical Facility Technician 1 to ensure the optimal operation of electrical, mechanical, and fire/life safety equipment within data centers. This role involves planned preventative maintenance, daily corrective work, and emergency response to maintain critical facility infrastructure. The technician will act as a technical expert, reporting to a program manager and collaborating with Onsite Engineering Operations (OEO) and third-party vendors. The primary goal is to support operated data centers and ensure mission-critical servers achieve over 99.999% uptime. The position requires adherence to safe working practices, including lockout/tagout and SDS procedures, and the ability to read and interpret various technical documents such as blueprints, wiring diagrams, and MOP/SOPs. Technicians will use hand tools and test equipment for installations, troubleshooting, and repairs under supervision, logging all activities in the CMMS. They will also assist higher-level technicians, train other staff, and conduct daily facility walk-throughs to document and analyze operational parameters like power availability, temperature, and humidity. A thorough understanding of site-specific processes, emergency operating procedures (EOPs), and the functionality of various critical equipment (e.g., UPS, generators, chillers, BMS, EPMS, fire alarm systems) is essential. Maintenance records must be kept in compliance with city, state, and EPA regulations, and building codes must be interpreted and applied. The role also involves identifying necessary materials for procurement and understanding heating and refrigeration cycles, including diagnosing and repairing related issues. Knowledge of power density, HVAC system capacities, and cooling/heat load calculations is also required.
