Founding Product Designer

Simple AI is building state-of-the-art voice AI agents for enterprise. Our realistic agents help iconic businesses like Doordash, xAI, and Omaha Steaks handle all kinds of phone operations, from customer support to order intake to lead qualification. We’re growing revenue like crazy and looking to bring on a founding product designer to help shape the future of our product as we scale rapidly. We are very excited about the potential for AI to change the world, and work out of our SF office 5 days a week.
