Collaboration Engineer, Senior

The Opportunity:
You’ll engineer and sustain the collaboration ecosystems that keep mission teams communicating across secure, distributed environments. From VoIP call flows to enterprise video conferencing, and SIP trunks to QoS tuning, you’ll ensure that every conversation, meeting, and message happens reliably, no matter the classification level or operational tempo.

You’ll architect and optimize voice and collaboration solutions that integrate seamlessly with secure networks, wireless infrastructures, and mission applications. You’ll modernize legacy unified communications (UC) platforms, improve call quality and resiliency, and build the high-availability frameworks that keep voice and video online for users who can’t afford downtime. Every call connected, every conference stabilized, every secure voice path delivered—your work keeps teams aligned and missions moving.

What You’ll Do:

• Engineer and maintain enterprise VoIP and UC environments such as Cisco CUCM, Unity, Expressway, Jabber or Webex, and Cisco or Ribbon SBCs.
• Design and optimize SIP call routing, dial plans, trunks, and voice gateways across classified and unclassified networks.
• Troubleshoot complex issues involving QoS, call signaling, codec negotiation, jitter or latency, and media path analysis.
• Deploy and support secure collaboration solutions, including video conferencing, softphone platforms, and on-prem or cloud hybrid UC systems.
• Integrate UC platforms with identity services, directory systems, messaging platforms, and network segmentation.
• Maintain and tune voice and video quality across LAN or WAN architectures in alignment with mission requirements.
• Support expansion, migration, or modernization of UC clusters and assist with high-availability and disaster recovery designs.
• Collaborate with network, cybersecurity, and infrastructure teams to maintain secure, compliant, and resilient collaboration environments.
