# Game Mathematician **Company:** Eeze **Department:** Engineering **Location:** Hammersmith **Remote status:** Hybrid **Language requirement:** English **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. - Opportunities for personal growth and learning - An open, inclusive and supportive team where you will be valued, and your suggestions will be welcome. - 26 days paid holiday per year. This is in addition to local bank holidays. - Competitive salary - €400 annual wellness Allowance - Hybrid Working - Risk Benefits such as pension, Life Assurance (4x annual salary), - Private Medical Insurance - Team Building Opportunities - Flexible core hours between 10am – 4pm - Receive support whenever you need it with our Employee Assistance Program, available 24/7. - Local discounts and more. _This position is no longer accepting applications._
