Over the last few years, Duolingo has expanded beyond language learning into entirely new subjects: Math, Music, and Chess.

We're looking for a Senior Director of Engineering to help lead Math and scale our teaching method to Physics, Chemistry, and more. This is a role for a builder. You’ll take on creating math education at scale, leveraging a world-class engineering team and AI-driven content generation system.

You’ll partner closely with Product and Design to shape the future of the product while building the organization that delivers it. This role is based in our New York, NY office on a hybrid (4+1) work schedule. 🧠 You will.
