About the Team

The Voice Agent team builds the real‑time systems that allow Decagon agents to carry natural conversations across our omnichannels (phone, web, mobile, etc). We work across speech understanding, audio streaming, synthesis quality, and the voice‑specific execution logic that enables timing, pacing, and responsive dialogue.

Our systems must remain accurate, responsive, and stable at scale. Voice is one of the most technically challenging surfaces in conversational AI, and our small team owns this entire capability end‑to‑end.
