Back Bay Networks is seeking a VoIP / Unified Communications Engineer to support and evolve voice and collaboration environments across our managed client base.

This is a hands-on engineering role focused on VoIP systems, SIP-based communications, and call flow design, with supporting network configuration as needed. You’ll work across multiple platforms, including Elevate UC, Microsoft Teams Phone, and other hosted VoIP systems, helping clients deploy, troubleshoot, and optimize their communication infrastructure.

Troubleshooting & Optimization

Diagnose and resolve call quality issues (latency, jitter, packet loss, one-way audio)
Analyze SIP signaling and call paths to identify and resolve issues
Monitor system performance and implement improvements to ensure reliability

Network Support (VoIP-Focused)

Configure and troubleshoot VLANs, QoS, and network settings impacting voice traffic
Work with firewalls and routers to ensure proper SIP/RTP handling (NAT, ACLs, QoS)
