Decagon is the leading conversational AI platform empowering every brand to deliver concierge customer experience. Our AI agents provide intelligent, human-like responses across chat, email, and voice, resolving millions of customer inquiries across every language and at any time.

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.

As a Staff Software Engineer focused on Voice Agent, you will lead the architecture and evolution of Decagon's voice platform. You will drive multi-quarter projects that improve timing, responsiveness, audio quality, and reliability across millions of interactions.

You will collaborate with Research to integrate the next generation of speech models, with Infra to push the boundaries of latency and performance, and with Product to bring new voice capabilities to customers. You will help set engineering standards for voice, mentor senior engineers, and raise the technical bar for one of Decagon's most important surfaces.
