Sportradar is the world's leading sports technology company operating at the intersection of sports, media, and betting. Within the iGaming (Playradar) division, you will design, validate, and optimize mathematical models for casino games including slots, instant-win games, crash-style games, plinko-style products, roulette-inspired mechanics, and number games.
As a Senior Game Mathematician, you will work independently on well-defined game math challenges while partnering confidently with Product, Game Design, Engineering, Compliance, and Commercial teams. Key responsibilities include:
- Design and develop mathematical models for RNG-based casino games, creating probability models, payout structures, volatility profiles, and RTP configurations
- Create, test, and document game simulations to support product development and certification readiness
- 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 in production systems
- Analyze post-launch game and player performance data, recommending 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 workstreams and solving complex problems independently
The role is fully office-based in Vienna, with the company valuing in-person collaboration, knowledge sharing, fast decision-making, and team connection as key drivers of innovation.
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
- Commercial experience designing, developing, and maintaining Java-based applications in production environments
- 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 including slots, table games, crash games, instant games, plinko-style mechanics, lottery, or number games
- 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 in fast-moving product environments where priorities evolve and pragmatic, high-quality solutions are needed
- Fluent written and spoken English with ability to produce clear specifications, analysis summaries, 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 combining sports content with casino-style mechanics
- Interest in innovation, prototyping, and building scalable mathematical frameworks for growing casino games portfolios
