Job description

Network & Telecom Engineer / Lead
Combined (Dual-Track) — Network & Voice/UC

Role Summary
Versatile senior engineer and technical lead to support both network and voice/UC services across local/office sites, data centers, and cloud. Owns incidents and changes end-to-end across the network-to-voice boundary — where problems are often mis-triaged between teams. Should be strong in one track and genuinely operational in the other.
Note: single-track specialists are also welcome (see the separate Network and Telecom job descriptions). This combined role suits engineers who can resolve cross-domain issues such as voice quality over the WAN, SIP connectivity through firewalls, and site turn-ups spanning LAN, wireless, and voice.

What You'll Support
• Network: Cisco Nexus / IOS-XE routing & switching (OSPF, BGP, vPC, VRF, QoS), Palo Alto firewalls (Panorama), Cisco wireless + FortiNAC, Client/TACACS, MPLS/IPsec WAN, and AWS/OCI connectivity.
• Telecom / UC: Cisco CUCM, Unity Connection, IM&P, Expressway, CUBE/Client and voice gateways, SIP trunks/DIDs, plus Zoom/Teams and contact-center platforms.
• Shared: local/office sites, data centers, and cloud (US, Canada, and international); SolarWinds and ServiceNow (ITSM/CMDB); PCI/SOC-regulated scope.

Key Responsibilities
• Own complex incidents and changes across both network and voice; lead end-to-end P1 bridges.
• Resolve cross-domain issues (QoS-for-voice, SIP-over-WAN, remote-access/MRA, DMZ/firewall, DNS/certificates) without re-triage.
• Deliver combined site turn-ups and IMACs spanning LAN/WAN, wireless, and voice.
• Perform root-cause analysis, manage vendor/Cisco TAC cases, and set technical standards across both tracks.
• Mentor and uplift frontline teams on both domains; keep documentation and the CMDB accurate.
• Partner on cross-domain design, automation, and continuous improvement.

Required Skills & Experience
• 10+ years spanning enterprise network and voice operations, including senior or lead-level responsibility across both domains.
• Documented production experience in the secondary track — not exposure only (e.g., a network-primary engineer who has run CUCM dial-plan and CUBE/SIP changes, or vice versa).
• Evidence of resolving network-to-voice incidents end-to-end is a strong differentiator.
• Comfortable with ITIL processes in ServiceNow and PCI/SOC boundaries; clear English able to lead cross-domain P1 bridges and write clean RCAs.

Certifications
• CCNP-level minimum in the primary track (Enterprise or Collaboration); CCIE strongly preferred.
• Supporting credentials: Palo Alto (PCNSE) and/or AWS/OCI networking for network-primary; certificate/security and Cisco TAC experience for voice-primary.
