Founding Engineer

As a founding engineer on a small conversational AI team, you will own the real-time voice layer, from incoming speech through AI reasoning to spoken responses. You will help make natural, responsive voice interactions work reliably in production, with a focus on end-to-end latency. The role involves building and optimizing streaming speech-to-text, LLM turn-taking, text-to-speech, and telephony or WebRTC transport systems. You will measure and reduce latency, address audio challenges, and build evaluation harnesses to guide product decisions.
