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. As we expand rapidly, we’re now continuing to build out our consumer-facing application that will bring our voice AI technology directly into the hands of everyday users.
We are growing revenue like crazy and looking to hire a talented software engineer to lead development of our origin story! We’re very excited about the potential for AI to change the world, and work out of our SF-based office 5 days a week.
