Who are we?

It’s pretty simple, really. IO Interactive is here to deliver exciting best-in-class gaming experiences. We want our games to play and feel like the people who created them – unique and creative. It is our way of making sure that we will always deliver something interesting.

So we do a lot to foster a culture of brother- and sisterhood and we strive to be a collective of creative, productive people rather than a factory. You come to work at Io-Interactive because you want to create top-of-the-line games and because you want to be part of a company that isn’t afraid of doing things differently.

Because you will be spending a substantial amount of your day here, we do as much as we can to make IOI feel like a second home. We meet for optional breakfast every morning, have communal lunches and even dinner on those occasionally long days where we need to meet an important deadline.

On Fridays we sometimes have our Friday bar – either planned as a big thing where we run around in the building with laser guns or other fun like that – or just spontaneously started somewhere in the building. Every now and then we have IOI days where we can dig into our pet projects or attend presentations from colleagues or external experts on everything game related. It’s all about getting creative, influenced and inspired.
