Game Mathematician

Game Mathematician Key Responsibilities Game Mathematics & Product Design Own the mathematical design and validation of new and existing games across live casino, table games, game shows, slots, and gamification products. Design and document RTP, volatility, hit frequency, payout distributions, pay tables, bet limits, jackpot mechanics, bonus mechanics, and other core mathematical parameters. Develop mathematical models for game mechanics, payout structures, side bets, bonus rounds, promotional mechanics, and proprietary game variants. Conduct feasibility analysis for new game concepts, identifying mathematical risks, commercial trade-offs, and regulatory considerations before development begins. Partner with Product Owners, Game Designers, Commercial, and Engineering teams to shape game mechanics that balance player experience, operator value, compliance, and business goals. Review competitor products and market trends from a mathematical and product-performance perspective to support roadmap decisions. Provide mathematical sign-off for game specifications and releases, ensuring implemented logic matches approved models and documentation. Simulation, Modelling & Quantitative Analysis Design, build, and maintain simulation models to validate game mathematics, estimate statistical properties, and test edge cases. Run large-scale Monte Carlo simulations and theoretical analyses to validate RTP, variance, volatility, confidence intervals, risk exposure, and payout behaviour. Develop efficient simulation tooling using vectorised computation, parallel processing, memorisation, and other optimisation techniques where appropriate. Produce analytical and numerical solutions for expected value, variance, conditional probabilities, distributional outcomes, and other key game metrics. Support real-time or near-real-time expected-value calculations for live game features, side bets, bonus mechanics, and monitoring tools. Create clear mathematical documentation, models, and reports that can be reviewed by internal stakeholders, auditors, testing labs, and regulators. Regulatory Compliance & Mathematical Documentation Prepare and maintain mathematical documentation required for internal approval, certification, testing labs, and regulatory submissions. Produce theoretical RTP calculations, simulation reports, game logic explanations, pay-table analyses, and statistical validation reports. Work closely with the Compliance Lead, who manages regulator-facing communication and formal submission processes. Ensure all game mathematics aligns with applicable regulatory, certification, and testing-lab requirements across relevant jurisdictions. Support audits, certification reviews, and regulatory queries by providing clear mathematical evidence and explanations. Advise on mathematical and statistical requirements for adjacent systems, including RNG, RGS, game servers, statistical monitoring tools, and reporting systems where required. Cross-Functional Collaboration & Stakeholder Management Act as the mathematical authority within the organisation, advising Product, Engineering, Compliance, Commercial, Operations, and senior stakeholders. Communicate complex mathematical concepts clearly to non-technical audiences. Challenge assumptions and identify risks in game designs, promotional mechanics, simulations, or implementation logic. Partner with Engineering to ensure mathematical models are implemented accurately and efficiently in production systems. Support Product and Commercial teams with data-driven insights into game performance, player behaviour, volatility, profitability, and product positioning. Identify opportunities to improve mathematical processes, documentation standards, simulation tooling, validation methods, and release governance. What We’re Looking For Required Qualifications & Experience Degree in Mathematics, Statistics, Mathematical Economics, Computer Science, Physics, Engineering, or another highly quantitative discipline. Proven experience, 2 years, as a game mathematician within iGaming, online casino, live casino, slots, table games, lottery, or a closely related gaming environment. Strong understanding of RTP, volatility, variance, hit frequency, pay-table construction, jackpot design, bonus mechanics, and payout modelling. Advanced knowledge of probability theory, combinatorics, statistics, stochastic processes, optimisation, and simulation methods. Ability to build, validate, and document mathematical models from concept through certification and production release. Experience producing or supporting mathematical documentation for regulated gaming markets, testing labs, or certification processes. Strong analytical and problem-solving skills, with high attention to detail and a rigorous approach to validation. Ability to explain complex quantitative concepts clearly to Product, Commercial, Engineering, Compliance, and executive stakeholders. Comfortable working independently in a role with high ownership and accountability. Desirable Experience Experience across multiple iGaming verticals, especially live casino, table games, slots, game shows, and gamification. Experience with jackpot systems, progressive prizes, side bets, missions, tournaments, free spins, drops, or reward-distribution mechanics. Knowledge of regulated iGaming markets, testing labs, and certification processes. Experience with machine learning, anomaly detection, advanced statistical modelling, or fraud/risk analytics. Knowledge of player-behaviour modelling, behavioural economics, game theory, or retention modelling. Experience working with data platforms, dashboards, BI tools, or production monitoring systems. Familiarity with RNG principles, RGS architecture, game-server logic, or casino platform integrations. What’s in it for you? Experience a dynamic and team-orientated work environment.
