Teams and roles

• Data: AI and machine learning, data science, and analytics.
• Product: product managers in growth, monetization, notifications, and the English Test, who own features from idea to experiment.
• Design: product designers, writers, researchers, and animators, with a portfolio of consumer mobile work.

Other roles are in marketing, learning design, and localization.

What they look for

Duolingo judges candidates on craft, leadership, and citizenship. It wants curious people who care about the mission and ship polished first versions. Interviews usually have a recruiter call, a talk with the hiring team, and a test such as live coding, a take-home, or a presentation. A virtual onsite about craft follows. Candidates must know the principles and bring examples of past impact.
