Electrical Mission Critical Service Technician

Company Overview

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.
