Senior Search Engineer

Quizlet’s mission is to help students (and their teachers) practice and master whatever they are learning. Every month over 30 million active learners from 130 countries practice and master more than 200 million study sets on every conceivable topic and subject. We are developing new learning experiences by modeling how students learn and by drawing upon knowledge acquisition, retention, and tracing pedagogy in cognitive science. We are always seeking to help students master any subject by optimizing study efficiency and engagement.

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 is a leading company in education technology with proven traction and huge growth ahead. Our business model is strong and got us to profitability before raising venture capital money. Come help us scale one of the fastest growing and highest quality consumer learning brands, as we develop innovative simple-to-use study tools that help students everywhere. Quizlet is a fun and unique company in a truly exciting phase of its growth.
