## Description

The Tier 3 Helpdesk Technician is the senior technical authority and the final escalation point before a service event is elevated to a vendor, manufacturer, or program management. This position holds full system programming and configuration authority across Video Surveillance Systems (VSS), Intrusion Detection Systems (IDS), and Physical Access Control Systems (PACS). Tier 3 operates primarily in a helpdesk and remote support capacity but conducts occasional site visits when a fault cannot be resolved through remote means or when a site requires direct technical assessment. Tier 3 also owns the team's technical knowledge base, ensuring troubleshooting guides, equipment records, and reference documentation are current and accurate. Pay will range from 67k - 75k annually based on a variety of factors.
