Upchurch is a rapidly growing, full-service building engineering company providing mechanical, plumbing, HVAC, and electrical services across the southeastern United States. Founded in 1970 and headquartered in Horn Lake, MS, Upchurch has grown through both organic expansion and strategic acquisitions, establishing a strong reputation for quality, reliability, and service excellence. We offer end-to-end solutions—from design and installation to ongoing maintenance and emergency support—helping clients maximize building performance, energy efficiency, and equipment lifespan.
Through our Data Center Mission Critical (DC|MC) business unit, Upchurch provides specialized operations and maintenance services focused on uptime, reliability, and lifecycle performance of data center infrastructure.
This role supports colocation, hyperscale, enterprise, and edge data centers by executing disciplined preventive, corrective, and condition-based maintenance on mission-critical cooling and mechanical systems.
The Electrical - Mission Critical Services Technician is responsible for maintaining, troubleshooting, pre-commissioning, and servicing electrical equipment and systems that directly support data center uptime and reliability. Unlike traditional comfort-cooling roles, this position operates in high-availability environments where procedural compliance, redundancy awareness, and precision execution are mandatory.
Technicians perform scheduled preventive maintenance (PM), corrective maintenance (CM), and emergency response activities on mission-critical cooling based on SLAs of 2-8 hours and mechanical systems while adhering to strict Method of Procedure (MOP), safety, and change-management standards.
Perform preventive and corrective maintenance on data center mechanical systems, including but not limited to:
Switchgear (low voltage and medium voltage)
Distribution (switchgear, power distribution units, automatic transfer switch, remote power panels)
Battery systems
Rectifiers, Inverters
UPS systems
General building electrical
Variable frequency drives.
