Career possibilities with growing team.

We’re looking for a Senior Game Mathematician — someone who sees patterns where others see chaos, and who understands that behind every “big win” there’s elegant math. You’ll shape the core of our games: design math models, define volatility and player experience, and turn ideas into numbers that actually feel right.

• Flexible schedule: start your day anytime between 08:00–12:00 CET;
