Our mission at Duolingo is to develop the best education in the world and make it universally available. It’s a big mission, and that’s where you come in!

At Duolingo, you’ll join a team that cares about finding innovative solutions to complex technical problems, running countless experiments (300+ at a time!) with our massive user base to make data-driven decisions, and educating our users and employees alike. You’ll have limitless learning opportunities, mentorship and collaboration with world-class minds, and a variety of projects with large scopes — while doing work that’s both fun and meaningful.

You'll work on adding new exercises that support our learners in practicing skills like recall and production in bite-sized formats, as well as creating other ways to help learners build foundational skills in a new language.

You’ll work on improving how we present subscription options across the app, highlight the value of our offerings, and craft delightful, high-impact conversion moments. We’re looking for engineers who are passionate about creating seamless, user-centered purchase flows and subscription experiences.
 
Social Area:
As an Android engineer on the Social Area, you'll build features to make social interactions a fundamental part of the core Duolingo experience. You will develop social features, own projects from end-to-end, iterate quickly based on experiments, and be a part of big bets that will help drive new rewards and deeper connections. The Social teams at Duolingo create ways for learners to engage socially, share their wins with each other, and get great rewards while learning. We're looking for engineers who are passionate about building fun, high-quality social experiences that will motivate learners.
