Full-time
Quizlet’s mission is to help students (and their teachers) practice and master whatever they are learning. Every month more than 50 million active learners from 130 countries practice and master more than 300 million study sets on every conceivable topic and subject. We are developing new learning experiences by modeling how students learn and drawing upon knowledge acquisition, retention, and pedagogy in cognitive science. We are always seeking to help students master any subject by optimizing study efficiency and engagement.

As part of the Core Backend Services team, you will redesign parts of the backend and build services to help scale Quizlet . Quizlet continues to add millions of users every day. To support the next 100 million users we’re building highly-scalable back-end services in the areas of content-management, communication, payments, search, and many more. This team will own this migration and pave the way for other teams to build new services.

Quizlet is a leading company in consumer learning technology with proven traction and huge growth ahead. Our business model is robust with two strong revenue streams — advertisements and paid subscriptions. Our ads business allows us to offer amazing study tools to millions of students around the globe for free. And our premium subscriptions give students and teachers the ability to create custom content and access learning analytics tools. 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.
