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 and English proficiency testing with the Duolingo English Test.

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.

You Will...

  • Conduct cutting-edge AI research that pushes forward the field of education
  • Work with a multi-functional team of award-winning designers, researchers, engineers, and others to build new research-based product features
  • Assist in mentoring junior scientists and engineers
  • Contribute to the broader research community by publishing and presenting about your work
  • A few example projects include:
  • The Duolingo English Test (TACL paper)
  • Novel bandit algorithm for mobile notifications (KDD paper)
  • Shared task on translation & paraphrasing (ACL paper)
  • Novel model of vocabulary forgetting (ACL paper)

You Have...

  • PhD in machine learning, AI, computer science, or a related technical field
  • Experience implementing ML systems in Python, Java, Scala, or C/C++ (i.e., not just R or MATLAB)
  • Outstanding interpersonal communication and organizational skills
  • Contributions to research communities and efforts, including publishing papers at conferences such as ACL, CVPR, EDM, ICML, NeurIPS, etc.

Exceptional Candidates Will Have...

  • Familiarity with educational and/or assessment technologies
  • Experience mentoring or managing junior scientists or engineers
  • Strong publication record

We will do everything we can within reason to make sure that your interview takes place in an environment that fairly and accurately assesses your skills. If you need assistance or accommodation, please contact your recruiter.

We aim to return to office, and as such are requiring all employees to be fully vaccinated against COVID-19 and have received any booster doses as recommended by the Centers for Disease Control and Prevention.

An Insider's view of Duolingo

What are some social events your company does?

I've really appreciated the high-touch, fun social activities that we've gotten to take part in – especially events like a virtual cooking class. I was so pleasantly surprised to get a personalized apron in the mail with my name on it, and learn how to make tacos from Duolingo's in-house chef!

What kinds of technical challenges do you and your team face?

We are part of a business unit (The Duolingo English Test) that was recently spun off into its own product. This means we have some technical debt we need to pay off because we had a lot of rapid growth. Our team also tackles ambiguous problems requiring research and development. We brainstorm and try various ideas until we have a working solution.

How does the company support your career growth?

When I first joined, I had no prior experience with iOS development. But I was eager to learn, and Duolingo was willing to invest in me. Duolingo provided me with the mentorship and resources to not only learn iOS, but become proficient enough to now build a new app from the ground up.

What’s the vibe like in the office?

Duolingo feels like a family. “Duos,” as we call ourselves, are these great people who strongly believe in our mission of creating free and accessible education. They are fun-loving people, and it’s the kind of company where you feel comfortable enough to hang out with people after hours to play games or just joke around.
