The engineer works across the full lifecycle: mapping a customer''s SIP trunks, CTI integrations, and CCaaS-specific APIs, building and hardening the signaling, media, and event integrations that connect those systems to ServiceNow''s Voice/CTI and Native Voice Controls platform, and proving through testing and production monitoring that calls connect, stay connected, and hand off cleanly under real network and carrier conditions. Ensure the audio, signaling, and event streams the connectivity layer delivers are clean, well-formed, and low-latency enough for the voice AI agents running on ServiceNow''s Voice ecosystem to operate correctly - partnering with agent engineering rather than building the agents yourself.
