• Engineer IP paging, public address, and overhead speaker systems using SIP-native or SIP-bridged endpoints.
• Engineer the network underlay required by voice and SIP services, including QoS marking and queueing for RTP, multicast routing for IP paging, VLAN segmentation, PoE budgeting, and switch port profiles.
• Coordinate with IT and InfoSec on SIP signaling security (TLS), media encryption (SRTP), session border control, perimeter design, and lawful logging of communications events into the enterprise SIEM.
• Design and operate the dispatch console architecture for the GSOC, integrating LMR, LTE PTT, SIP intercom, and mass notification under a unified operator experience using Genetec Mission Control SOPs.
• Maintain interface documentation and network diagrams for every site, including donor antenna locations, BDA placement, head-end distribution, and SBC connectivity.
• REQUIRED QUALIFICATIONS
• Bachelor's degree in Electrical Engineering, Communications Engineering, Computer Science, Information Technology, or a related technical field, or equivalent practical experience.
• Hands-on SIP architecture and operations: SIP, SDP, RTP, SRTP, TLS for SIP signaling, codec selection, dial plan design, and Session Border Controller configuration.
• Direct experience integrating SIP intercom platforms with a video management or access control system, ideally Genetec Sipelia integrated with Security
