About Us:

Headquartered in Dallas, Texas, Divcon delivers fully integrated automation solutions nationwide that optimize performance, energy efficiency, and reliability across HVAC, lighting, power monitoring, and mission-critical systems. Leveraging advanced technologies—including Allen-Bradley PLCs, Ignition SCADA, and Delta DDC systems—we combine deep technical expertise with field-tested execution to deliver precise, scalable, and high-performance solutions.

The Service Preventative Maintenance Technician is responsible for performing scheduled preventative maintenance and remote system health checks for Divcon customers’ Delta Controls Building Automation Systems (BAS).

This role focuses on routine inspections, system verification, minor adjustments, and documentation to ensure customer systems remain reliable, optimized, and operating according to Divcon standards. The PM Technician supports proactive service delivery and helps identify issues before they escalate into corrective service calls.
