EF LEARNING LABS is the tech hub of EF Education First. We’re an international team of over two hundred engineers spread over three primary cities - London, Boston, and Shanghai.

Our front-end battalion is a close-knit team of 20. When we’re not working to deliver happiness to over nine million language learners, we’re playing foosball in the kitchen, owning the product managers at table-tennis, spiking the designers’ sodas with baijiu at Happy Hour Fridays in our stadium, and contributing to top-notch open source projects born out of our daily crunch.
