Senior ML Engineer — Scalable AI & Personalization

In 2005, 15-year-old Andrew Sutherland was a sophomore in high school facing a familiar challenge: he needed to study for a French vocabulary test. Frustrated with traditional paper flashcards, he built a simple tool to help him learn more effectively. That tool would grow into Quizlet, now the world's largest student and teacher online learning community. What started as a personal project to memorize French words has evolved into a platform serving tens of millions of students every month, including two-thirds of U.S. high schoolers and half of U.S. college students, powering over 2 billion learning interactions monthly.

Today, Quizlet blends cognitive science with machine learning to personalize and enhance the learning experience for students, professionals, and lifelong learners alike. The company operates on a freemium business model with growing revenue streams from subscriptions and advertising, maintaining its commitment to accessibility while building sustainable growth. Based in San Francisco with a growing team, Quizlet continues to innovate AI-powered learning tools that scale across the world, driven by the core belief that anyone can learn anything with the right tools and guidance.
