Game Mathematician in London

Key Responsibilities

• 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.
• 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.

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.
