Senior Conversational Designer

About the role

Hello Patient is hiring a Senior Conversational Designer to shape how our AI agents communicate with patients in real, high-stakes conversations. This is a senior individual contributor role that sits at the intersection of product, behavior, and language. You'll improve and refine live agent behavior in production - helping our systems become more effective, more reliable, and more human in real-world conditions. Our agents have seconds to build trust, handle objections, and complete tasks without human intervention. You'll work closely with Product, Engineering, and QA to evaluate how conversations perform in production, identify failure modes and missed opportunities, and translate those insights into better conversational behavior. You'll also help raise the bar for conversational quality across the team by reviewing work, contributing frameworks and best practices, and helping less experienced teammates develop stronger instincts. We're looking for someone who combines strong language judgment with practical experience building or improving AI-driven conversational systems. The right person is thoughtful, rigorous, highly curious, and excited by solving ambiguous problems through iteration in a fast-moving environment.
