Founding Engineer

About Simple

Simple AI makes super realistic voice AI powered agents. We help all kinds of big businesses handle their phone operations, from customer support and order intake at e-commerce stores, to lead qualification for insurance brokers. We are growing like crazy (doubling MoM in revenue) and looking to hire our first 1-2 founding software engineers to help us both stay afloat of current customer demand, and help build out systems that will stay ahead of future problems.

Based in San Francisco, Simple AI is backed by Y Combinator, top VCs, and angels like Michael Seibel (co-founder of Twitch), Jared Friedman (Scribd), Alexandr Wang (Scale AI), Matt Van Horn (June Oven and Lyft), Suhail Doshi (Mixpanel), JJ Fliegelman (WayUp) and Scott Wu (Cognition).

The team

We have a tiny, talented team of 3. The founders (Catheryn and Zach) met while each 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 UChicago and led software at Evil Geniuses. We just added Mitchell to the team, the most educated of us with a BS from Yale and PhD in applied math from MIT.
