About You

You are a focused, creative, smart, intrinsically motivated game dev. You enjoy working on a small, focused team and building things that millions of people play. You appreciate working with people who care about impact over hours worked, and who appreciate that you are amazing at identifying the 20% that gets us 80% of the way and then building them.

You enjoy going from batting around ideas to execution to deployment in super short cycles, and you like that you have a real voice on the team. You appreciate being a peer with other driven, skilled and focused people. You understand that some structure is beneficial to help humans work together, but you also feel comfortable raising a flag if the process gets out of hand. You don’t accept broken windows, and you don’t get overly bogged down perfecting every detail - the point is to create great experiences for players and move forward fast.

You’re also the type of person who dives fearlessly into internal and external code bases to find the bugs, the extra frames per second or the memory that you need to prove that given enough engineering talent (and grit), this game can feel good and run well even on a potato!
