Senior Game Engine & Tools Engineer

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 procedurally generated and user‑customizable. Students use this in the classrooms to learn to work collaboratively to build on the island, and teachers can use it 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, the underlying game engine, the internal game editor (Dojo Creator) and the scalable cloud infrastructure that powers Dojo Islands. As an engineer on the team, you will bring your expertise in one or more of the game subsystems—rendering, networking, avatars, and performance engineering—to help deliver the highest‑quality game to our players. You will also build gameplay functionality with a modular, systems‑first approach. Your creativity in prototyping fun gameplay and game‑design ideas will be validated and shipped to production with very high quality. You will collaborate with other engineers and cross‑functional team members in a continuous‑delivery environment.
