The Data Center Technician provides a working level of data center knowledge and is responsible for the operational integrity and regulatory compliance of the data center electrical, mechanical, and fire life safety systems. The technician maintains and follows the processes that maximize customer uptime in the most cost‑effective way, ensuring that data center problems are identified and repaired quickly, contractors deliver quality services, and internal customer demands are met.

• Develop creative approaches to keep operational costs to a minimum, improve efficiency, and implement new strategies.
• Mechanical responsibilities: chilled water systems and components, HVAC systems such as rooftop units, CRAC/CRAH units, and humidification systems.
• Electrical responsibilities: electrical/critical power distribution from the utility/generator main switch gear through the UPS systems to the customer load.
• Fire Life Safety responsibilities: wet sprinkler systems and pre‑action sprinkler systems and their associated detection devices.
• Test performance of electromechanical assemblies and electronic voltmeters.
• Read blueprints, schematics, diagrams, or technical orders to determine methods and sequences of processes.
• Inspect parts for surface defects and install electrical or electronic parts and hardware in housings or assemblies using hand tools.
• Align, fit or assemble component parts using hand or power tools.
