  • Own network and voice architecture: define target architectures, standards, and roadmaps; drive lifecycle, patching, capacity planning, and resiliency patterns.
  • Own perimeter and remote access services including firewall platforms, VPNs, secure internet access, private access controls, and cloud-delivered security enforcement; maintain policy governance and periodic reviews with Security.
  • Deliver reliable cloud and partner connectivity: routing, external DNS dependencies, secure ingress/egress, and least-privilege network access.
  • Ensure voice and contact center quality: QoS design, monitoring, troubleshooting, and provider management.
  • Partner with OT stakeholders to keep OT/SCADA and IoT connectivity safe, segmented, and supportable.
  • Manage carriers, cellular providers, OEMs, and MSPs; own SLAs, escalations, and cost awareness.
  • Track and report KPIs (availability, latency, packet loss, MTTR, change success rate, voice quality/MOS).
  • Maintain accurate documentation and diagrams (circuits, sites, devices, external DNS domains/zones, DNS forwarders, dependencies) in the ticketing/knowledge system and CMDB.

  • Voice fundamentals (SIP/RTP, codecs, call quality drivers).
  • Leadership in incidents and change: clear communication, calm execution, and strong operational discipline.
  • Automation mindset (scripts, templates, Infrastructure-as-Code where applicable) and comfort leveraging generative AI to accelerate analysis, documentation, and troubleshooting workflows.
