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.

We’re a team of people who left safe jobs to build something better. No bureaucracy, no pointless meetings — just sharp minds building games that stand out.

🎲 What you’ll do

• Prototype and simulate gameplay mechanics to test balance, volatility, hit rates, and potential;
• Reverse-engineer competitors’ math to understand and improve on the best mechanics in the market;
• Collaborate with producers and developers to bring your math to life — ensuring technical and creative integrity;
• Run simulations, build reports, and validate results in Excel or via your own scripts/tools;
• Prepare clear documentation for internal reviews, certification, and release;
• Analyze performance data of live games, providing actionable insights for tweaks and next iterations.

🧠 What you bring

• 3+ years of experience in slot game math design (or similar gambling / probability-based products);
• Advanced Excel and solid programming/scripting knowledge (Python, R, or similar);
• Deep understanding of RTP, volatility, hit frequency, max exposure, feature math, and player behavior;
• Obsessive attention to detail — and ability to explain complex systems clearly;
• Collaborative mindset: you enjoy working with creative and technical people to make something that just feels good;
• Fluent English.

💎 Nice to have

• Experience with internal math simulators or your own simulation tools;
• Familiarity with regulatory / certification requirements for game math;
• Curiosity for game design and player psychology — not just numbers.

🎁 Benefits

• 21 vacation days + 5 extra day-offs annually;
• 12 paid sick days;
• Fully remote format — work from anywhere you feel productive;
• Flexible schedule: start your day anytime between 08:00–12:00 CET;
• Fixed budget for health insurance and gym/fitness;
• Provided all required work equipment;
• Zero bureaucracy and direct communication with founders and C-level;
• Minimal meetings, async-friendly workflow;
• Startup energy: fast motion, creativity, and tight-knit communication;
• Business trips and team meetups several times per year;
• Multiple salary payout options (flexible formats);
• …And many more perks unlocked after we hit break-even.
