Understanding customer problems through interviews and market research and translating them into requirements is critical. What You’ll Do: Drive B2 product strategy and roadmap development through to delivery execution. Lead the end-to-end product development lifecycle from discovery through delivery in feature development. Gather and synthesize

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

In this role, your mission is to help build a product ecosystem where reliability, privacy, and performance are non-negotiable. You will develop reusable components and resilient architectures that exude trust, ensuring that every patient interaction is seamless and every clinical data point is secure. You will be a "multiplier," creating the foundational frameworks that allow us to deploy 5-star experiences across a portfolio of partners without sacrificing the quality our users depend on. This role requires onsite presence in our New York City office 4 days a week and does not provide immigration support. What you will do Full-Stack: Support the end-to-end lifecycle of products and features, from multi-platform clients, to the Kotlin/JVM-based backend services that power them. Quality as a Feature: Enforce standards for high-stakes engineering—ensuring that performance, accessibility, and data privacy are baked into every feature Platform Innovation: Proactively modernize our systems to leverage agentic AI tools that improve developer productivity and team efficiency. Technical Stewardship: Act as a stabilizing force in complex technical situations, bringing clarity to ambiguous requirements and making informed decisions that mitigate risk. Mentor & Multiply: Level up the engineering organization by fostering an ownership mindset and modeling how to move fast while maintaining clinical-grade quality. What we are looking for Established Expertise: 3-5+ years of professional software engineering experience, with a deep focus on building robust, customer-facing products from front-to-back. Full Stack Fluency: Strong profession
