About the role For years, avatars have been something you watch. You write a script, we render a video, someone presses play. That model has taken AI video a long way but it has a ceiling. A video can't answer a question. It can't read the room. It can't role-play a tough conversation and adapt when you push back. We're changing that. Interactive Avatars listen, talk, and respond in real time; inside your product, your website, or your internal tools. You bring the logic and the language model; we power the avatar layer: the speech, the expression, the listening, the sense that there's someone actually there. It's early. Interactive Avatars is in closed beta today, and the teams building on it are pushing it into places we didn't expect - AI sales reps, always-on support agents, interactive trainers, onboarding guides. We're hiring a Product Manager to own it and take it from beta to a platform that thousands of developers build on. This is a role with real scope. You'll help define what a real-time avatar API should be, the surface developers integrate against, the experience end users feel, and the commercial model that makes it a business. You'll work directly with the engineering and research teams building the real-time avatar stack, and with the design partners already live in the beta. The problem you're solving Today, a developer who wants a lifelike, real-time avatar in their product has to stitch together a streaming pipeline, a rendering layer, an agent, and a set of hard real-time problems - latency, interruption handling, listening behavior, expressiveness, consistency across sessions, most of which have nothing to do with the product they're actually trying to build. We have the avatar technology and a working beta. What we need is a PM who can turn that into an API a developer can integrate in an afternoon, trust in production, and build a real business on top of, all while holding a quality bar high enough that the experience feels human, not uncanny. What you'll be doing Owning the end-to-end Interactive Avatar API. This is the developer-facing surface (SDK, integration patterns, docs), the real-time experience quality, and the path from closed beta to general availability, a
