About the role

Our mission at Duolingo is to develop the best education in the world and make it universally available. We’re expanding beyond languages to bring joyful, effective learning in new domains – Math, Music, and Chess. These are early but strategically critical bets for Duolingo, and we need exceptional data science leadership to shape what success looks like.

We’re looking for a trailblazing, hands-on staff-level data scientist to define and build and expand data science in our New Subjects pillar. You will be a pivotal DS voice in this space: setting the vision, leading with metrics, and embedding experimentation into how we build. You will establish and manage a team of data scientists in the pillar, with a strong IC self-focus in the beginning. If you’re excited to influence the future of education and build from the ground up, this is your moment.
