Senior Game Engineer

ClassDojo's goal is to give every child on Earth an education they love. We started by building a powerful network for communication. ClassDojo’s flagship app is the #1 communication app connecting K-12 teachers, children, and families globally. Teachers use it to share what’s happening throughout the day through photos, videos, and messages that make parents feel like they’re there. It’s actively used in over 95% of US schools, reaching over 45 million children in 180 countries, with a team of just around 200 people [1]. We are now beginning to use this network to give kids the best learning experiences in the world, far beyond those a standard school can provide. We hire for talent density. Our team comprises the most talented, entrepreneurial, and innovative teammates from around the world, with experience in education and large scale consumer internet companies, including Instagram, Netflix, Dropbox, Stripe, Uber, Y Combinator, and more. We’re building a company where the most talented people want to work. We believe you’ll do the best work of your life here—and you’ll pioneer the future of education, too. What you’ll do: ClassDojo is looking for people to join our virtual worlds platform team. Dojo Islands, our virtual playground, is being used by millions of kids in classrooms and at home. The world is a voxel-based environment with dynamic systems and deep player customization. Students use this in the classrooms to learn to work collaboratively to build on the island and teachers can use this to set up STEM activities for the kids to collaborate on. The virtual world is built using web technologies with the goal that it is performant and scalable on the low end devices used in schools or at home. This includes a wide range of chromebooks, tablets (iOS and Android) and web browsers. The Monsterverse team is responsible for building the Dojo Islands game, underlying game engine, internal game editor (Dojo Creator) and the scalable cloud infrastructure that powers Dojo Islands.
