Senior Unified Communications Engineer-797

JOB SUMMARY

This position serves as the lead engineer and subject matter expert for the organization’s Cisco VoIP and unified communications environment. The role is responsible for the day-to-day operation, reliability, security, and continual improvement of the Cisco telephony, voicemail, contact center, and emergency calling platforms that support the organization and the public it serves. The Cisco VoIP Engineer is responsible for all aspects of the Cisco voice environment, including Cisco Unified Communications Manager (Call Manager), Unity Connection voicemail, Unified Contact Center Express, Unified Intelligence Center, Cisco Finesse, Emergency Responder, all Cisco IP phones, Jabber clients, and remote worker telephony, including E911 services delivered through RedSky.
This role owns the full lifecycle of these systems, including physical hardware maintenance, operating system and application software maintenance, patching and upgrades, backups and disaster recovery readiness, testing, monitoring, troubleshooting, and documentation. Because telephony, contact center, and 911 services are mission-critical, the position requires a dependable, detail-oriented engineer who can work independently, communicate clearly with users and leadership, and respond quickly to service-impacting events. While the role includes collaboration with broader IT teams, it is intentionally structured to remain highly hands-on, requiring deep technical expertise in Cisco Unified Communications technologies and a strong commitment to customer service, operational excellence, and continuous improvement.
