CodeCombat (http://codecombat.com/about) is a programming game for learning to code. We are currently 15 people, funded by a16z and YC, in SF, aiming to level up computer science education both in and out of the classroom. Long term, we are evolving education through game-based learning. We're open source and looking to add a core engineer, curriculum developer, and game designer to our SF team, and a customer support specialist part-time remote.
