About Simple
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 qualifications. We are growing revenue like crazy and looking to hire AI Agent Engineers to help us stay afloat of current customer demand and also build out systems for the future. We are very excited about the potential for AI to change the world, and work out of our SF based office.
Simple AI raised $14M from world-class investors and operators like Y Combinator, First Harmonic, Massive Tech Ventures, Michael Seibel, Jared Friedman, Alexandr Wang, Matt Van Horn, Suhail Doshi, and Scott Wu.
The Team
The founders (Catheryn and Zach) met while running software teams at YC, where they shipped tons of new products for YC founders, including YC’s co-founder matching site. Cat previously worked at Instagram and Facebook and earned degrees in math and computer science at MIT. Zach previously studied computer science and statistics at U Chicago and led software at PEAK6. We have grown into a strong team of 20+ and are continuing to scale quickly.
About the Role
We are looking for an AI Agent Engineer to work directly with customers and help turn Simple’s voice AI platform into production-ready agents for each business.
This is a highly technical and highly customer-facing role. You will work across pre-sales and post-sales: building custom demos for prospective customers, understanding customer workflows, deploying agents, debugging edge cases, improving performance, and turning customer feedback into product improvements.
Every customer has different call flows, systems, products, policies, and edge cases. You will be responsible for understanding those details and making sure the agent works reliably in the real world. This role is a good fit for someone who wants to code, talk to customers, move fast, and be close to the business impact of what they build.
