Search is the engine that connects users with the best possible learning materials to efficiently master or teach any subject. We have unique technical challenges that you'll tackle as a search engineer, from optimizing the flashcard discovery experience to content recommendations to helping students decide which concepts to study next. Our search experiences are extraordinarily high throughput, serving thousands of requests per second over terabytes of data.

Quizlet’s mission is to help students (and their teachers) practice and master whatever they’re learning. We provide engaging and customizable activities with content contributions from people everywhere (over 200 million study sets and counting). We have fanatical users, significant organic growth, and a strong business model that got us to profitability before raising venture capital money.
