Backed by a $20M Series A and 80,000 gaming communities, Mushroom.gg’s mission is to be the social platform that unites the countless gaming worlds people inhabit, helping us all better find meaning in our digital lives through each other. We’re combining the best parts of social networks and MMOs to build a next-generation social media product for gamers everywhere on every platform. We build tools that make it easier than ever for gamers to create a digital identity, make their gameplay more social, and grow strong friendships along the way. It’s challenging for gamers today to build an active network to play and share moments of glory with; Mushroom makes it easy. Our vision is of a digital world filled with incredible games and communities, where the social connections and context are unbounded by physical limitations but are just as rich and real as they are in physical space. There are already 3 billion gamers in the world today, and in the not-so-distant future everyone will be a gamer. Join us now to build the social platform for gamers to find connection and meaning together! https://mushroom.gg/careers
