Upchurch
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 . Upchurch is a 50+ year building engineering firm delivering mechanical, electrical, plumbing, and controls services across the southeastern United States. Through our Data Center Mission Critical (DC|MC) business unit, Upchurch provides specialized operations and maintenance services focused on uptime, reliability, operational visibility, and lifecycle performance of data center infrastructure. This role supports colocation, hyperscale, enterprise, and edge data centers by executing disciplined preventive, corrective, commissioning-support, and condition-based activities on mission-critical controls, BAS/BMS, EPMS, DCIM-adjacent, and integrated building automation systems . Role Summary The Controls – Mission Critical Services Technician is responsible for maintaining, troubleshooting, validating, and supporting controls systems that directly impact data center uptime, system visibility, alarming, sequencing, and operational reliability. This role works across BAS/BMS platforms, EPMS interfaces, control panels, sensors, actuators, networked controllers, graphics, alarm points, sequence-of-operation logic, and integration points between mechanical, electrical, and facility operations systems. Unlike traditional controls service roles, this position operates in high-availability data center environments where procedural compliance, redundancy awareness, change control, documentation accuracy, and live-site discipline are mandatory. Controls technicians must understand that improper setpoint changes, failed sensors, communication loss, overridden points, or incorrect alarm logic can create significant operational risk. Technicians perform scheduled preventive maintenance, corrective maintenance, troubleshooting, point-to-point verification, alarm validation, controls readiness checks, commissioning support, and emergency response activities while adhering to approved Methods of Procedure (MOPs), Standard Operating Procedures (SOPs), Emergency Operating Procedures (EOPs), safety requirements, and change-management standards . Key Responsibilities Perform preventive and corrective maintenance on data center controls and automation systems, including but not limited to: BAS/BMS controllers and field panels. EPMS and power-monitoring interface points. DCIM-adjacent monitoring and integration points. Control panels, relays, terminal blocks, low-voltage wiring, and communication modules. Temperature, humidity, differential pressure, static pressure, airflow, leak detection, and equipment status sensors. Dampers, actuators, valves, VFD control interfaces, and controlled devices. CRAH/CRAC, AHU/RTU, fan wall, chilled water, pump, cooling tower, adiabatic, and liquid-cooling control interfaces. UPS, generator, ATS/STS, switchgear, PDU, RPP, and electrical monitoring points where applicable. Alarm points, trend logs, graphics, setpoints, schedules, and sequence-of-operation logic. Execute work through the approved field management system using approved MOPs, SOPs, EOPs, and change-management processes. Maintain awareness of redundancy, upstream/downstream impacts, stacked risk, and potential consequences of controls changes. Support alarm response, degraded performance investigations, sensor failures, communication loss, control-loop instability, and emergency service calls per SLA. Perform point-to-point verification, sensor validation, command/feedback checks, trend review, and controls readiness inspections. Support startup, functional testing, integrated systems testing, and turnover activities as assigned. Document work performed, readings, screenshots, trends, deficiencies, alarms, corrective actions, and system conditions accurately. Follow strict safety protocols, including LOTO, PPE, low-voltage electrical safety, site access rules, tool control, and live-site restrictions. Participate in scheduled maintenance windows, on-call rotations, after-hours response, and outage-support activities.
