Senior Director of Engineering, New Subjects 

From Duolingo’s posting

... Over the last few years, Duolingo has expanded beyond language learning into entirely new subjects: Math, Music, and Chess. These products reach millions of daily active users, are growing quickly, and represent a CEO-level bet that Duolingo can become a platform for learning anything. We're looking for a Senior Director of Engineering to co- lead our newest subjects, responsible for building and scaling products ranging from early stages through to some of the company’s fastest-growing initiatives. This is a role for a builder. You'll make decisions about which subjects to invest in, how to allocate engineering resources across bets at different stages, where to continue investing and where to pivot.
