Sportradar is seeking a Senior Game Mathematician to design, validate, and optimize mathematical models for casino games within its iGaming (Playradar) division. You will work on a diverse portfolio including slots, instant-win games, crash-style games, plinko-style products, roulette-inspired mechanics, and number games.
Key responsibilities include:
- Design and develop mathematical models for RNG-based casino games, ensuring engaging gameplay and compliant RTP structures
- Create, test, and document probability models, payout structures, volatility profiles, and game simulations
- Partner with Product Managers and Game Designers to translate game concepts into mathematically sound mechanics that balance player engagement, commercial objectives, and regulatory requirements
- Run simulations, analyze outcomes, and validate game performance against expected probability distributions, hit frequency, variance, and maximum exposure
- Prepare clear mathematical specifications and documentation for Engineering, QA, Compliance, and external certification partners
- Collaborate with Engineering and QA to ensure correct implementation and verification of game math logic
- Analyze post-launch game and player performance data and recommend improvements to mechanics, balancing, volatility, retention, and monetization
- Contribute to the Casino Games roadmap by identifying mathematical opportunities for new mechanics and scalable game templates
- Operate as a proficient individual contributor, taking ownership of assigned game math workstreams and solving complex problems independently
This is a fully office-based role in Vienna, with flexible working hours. The company values in-person collaboration, knowledge sharing, and fast decision-making.
REQUIREMENTS:
- 3+ years of relevant experience in game mathematics, probability modelling, statistical analysis, data science, applied mathematics, or comparable analytical role, ideally within casino gaming, iGaming, online games, or digital entertainment
- Strong understanding of probability theory, combinatorics, statistics, simulations, variance, RTP, hit frequency, and payout modelling for RNG-based games
- Ability to develop, validate, and clearly document mathematical models for casino games with limited supervision
- Experience with analytical tools and programming/scripting languages such as Python, R, SQL, Excel/VBA, MATLAB, or similar tools for simulations and statistical modelling
- Good understanding of casino game mechanics (slots, table games, crash games, instant games, plinko-style mechanics, lottery, number games) and how mathematical models influence player experience
- Strong analytical judgement with ability to identify risks, validate assumptions, and explain complex mathematical concepts to non-technical stakeholders
- Collaborative working style with ability to partner effectively across Product, Game Design, Engineering, QA, Compliance, and Commercial teams
- Comfortable working in fast-moving product environment where priorities evolve
- Fluent written and spoken English with ability to produce clear specifications and stakeholder-ready explanations
NICE TO HAVE:
- Hands-on experience creating math models for certified real-money casino games
- Knowledge of market-specific gaming regulations, lab certification requirements, or game math approval processes
- Experience with sports-themed or branded casino games
- Interest in innovation, prototyping, and building scalable mathematical frameworks
