Jobs & internships

We create fun. We do this by creating games: Serious Games that can be used to teach and train new skills, change perceptions, and share new ideas with the goal of changing the world for the better, bit by bit. That last part is reflected in our core values: trust, openness, transparency and equality.

We’ve being doing this for nearly twenty years and we’re good at it. Our games have won awards and we have international clients and partners in the sustainability, education, and healthcare sectors.

Our brilliant team is made up of creative people across a wide range of disciplines and since we are growing, we need someone to help herd the cats. Not literally, obviously, we don’t have any cats in the office, just the occasional doggies. Not that cats wouldn’t be welcome, of course they would. Which is a cute way of saying: our team is diverse and open to more diversity.
