Staff AI Research Scientist
Our mission at Duolingo is to develop the best education in the world and make it universally available. But we’ve got more left to do — and that's where you come in!
Duolingo is the most popular language-learning application in the world, with over 500 million users and over half a billion exercises completed daily. Beyond our core learning product, we have also entered into literacy with Duolingo ABC, English proficiency testing with the Duolingo English Test, and even Math.
We are passionate about educating our users, making fact-based decisions, and finding innovative solutions to complex problems. We offer meaningful work, limitless learning opportunities, and collaboration with world-class minds. Come brighten your life and over half a billion more!
As an AI Research Scientist, you will apply your background in AI and machine learning to invent the technologies that will define the future of education in areas such as personalization, natural language processing, speech, and so on. In many cases, this means identifying entirely new research problems, or synthesizing work that spans several fields. You will find opportunities to improve existing systems – or reinvent them completely – to tackle Duolingo's unique data. We are a fun and motivated team, building intelligent software used by millions of people around the world every day.
