Posted: May 14, 2026

Job Description

We’re looking for a Senior / Lead 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 products: design and own math models, define volatility and player experience, and turn ideas into numbers that actually feel right — while guiding others and raising the overall quality of the team.

What you’ll do

  • Take ownership of the full math direction for one or multiple game titles;

  • Drive innovation in game mechanics and math design, proposing new approaches and features;

  • Partner closely with product and business teams to align math with KPIs and market goals;

  • Make high-level decisions on risk, volatility profiles, and long-term game performance;

  • Improve internal tools, simulation processes, and math pipelines;

What you bring

  • 5+ years of experience in slot game math or similar complex probability systems;

  • Strong ownership mindset: you can lead a feature/game from idea to post-launch analysis;

  • 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;

  • Experience mentoring others or leading small teams/projects;

  • Ability to balance creativity with business impact (retention, monetization, engagement);

  • Confident communication: you can explain and defend your decisions to both technical and non-technical stakeholders;

  • Fluent English.

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 08:00–11:00 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.
