Join us as Junior Game Designer on our existing and upcoming games!

Want to learn how strategy games are really made?

 As a Junior Game Designer on the Supremacy Franchise, you'll work on feature design, balancing, and documentation for live games with millions of active players. Senior Designers and the Lead Game Designer will mentor you through the work, help you develop your skills, and teach you how to think like a designer.
You're learning by shipping real work. You'll contribute to features, take on design challenges, and build expertise on games that keep players engaged for months and years. Your job is growing into a designer who understands not just what works, but why

• Collaborate with Tech, Art, QA, and UI/UX to bring features to life

• Playtest regularly, identify issues, and suggest improvements

• Grow your design skills through hands-on work, mentorship, and feedback

• Take initiative within your scope by spotting improvements and contributing ideas
