Job description

About the Role

This role focuses on designing, validating and optimising the mathematical models behind casino games, ensuring engaging gameplay, robust probability logic, compliant RTP structures and commercially successful game mechanics. It sits within the iGaming (Playradar) division, which builds casino games, virtual sports, live betting products, 24/7 experiences and other innovative gaming concepts inspired by the world of sports. The position works closely with Product, Game Design, Engineering, QA and Compliance, and is suited to someone who can work independently on well-defined game math challenges while contributing hands-on expertise to a fast-growing casino games portfolio.

Key Responsibilities

• Design and develop mathematical models for casino games, including slots, instant-win games, crash-style games, plinko-style products, roulette-inspired mechanics, number games and other RNG-based gaming experiences.
• Create, test and document probability models, payout structures, volatility profiles, RTP configurations and game simulations to support product development and certification readiness.
• 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, analyse outcomes and validate game performance against expected probability distributions, hit frequency, variance, maximum exposure and target RTP.
• Prepare clear mathematical specifications and supporting documentation for Engineering, QA, Compliance and external certification partners.
• Collaborate closely with Engineering and QA to ensure the correct implementation, testing and verification of game math logic in production-ready casino games.
• Analyse game and player performance data after launch and recommend improvements to mechanics, balancing, volatility, retention and monetisation.
• Contribute to Playradar's Casino Games roadmap by identifying mathematical opportunities for new mechanics, differentiated game experiences and scalable game templates.
• Operate as a proficient individual contributor, taking ownership of assigned game math workstreams, solving complex but defined problems independently and escalating risks with clear recommendations.

Required Experience & Qualifications

• 3+ years of relevant experience in game mathematics, probability modelling, statistical analysis, data science, applied mathematics or a comparable analytical role.
• 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 in designing, developing and maintaining Java-based applications in production environments.
• Experience with analytical tools and programming or scripting languages such as Python, R, SQL, Excel/VBA, MATLAB or similar tools used 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, and how mathematical models influence player experience.
• Strong analytical judgement with the ability to identify risks, validate assumptions and explain complex mathematical concepts to non-technical stakeholders.
• Collaborative working style with the ability to partner effectively across Product, Game Design, Engineering, QA, Compliance and Commercial teams.
• Comfortable working in a fast-moving product environment where priorities evolve and pragmatic, high-quality solutions are needed.
• Fluent written and spoken English, with the ability to produce clear specifications, analysis summaries and stakeholder-ready explanations.

Preferred Skills

• Experience within casino gaming, iGaming, online games or digital entertainment.
• Experience with certification processes, regulated gaming environments, responsible gambling considerations or jurisdiction-specific RTP requirements is an advantage.
• 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, including products that combine sports content with casino-style mechanics.
• Interest in innovation, prototyping and building scalable mathematical frameworks for a growing casino games portfolio.

Workplace

• The role is fully office-based, with flexible working hours offered; the company values in-person collaboration, knowledge sharing, fast decision-making and team connection.
• Certain exemptions may apply depending on location.

Salary

• Competitive salary

Benefits & Perks

• Attractive benefits package.
• Shape the mathematical foundations of one of the most exciting and fast-growing portfolios in sports entertainment, casino gaming and iGaming.
• Create game math models that directly influence player experience, product performance and the commercial success of casino games played by audiences worldwide.
• Collaborate with talented colleagues across Product, Game Design, Engineering, QA, Compliance and Commercial teams in a highly collaborative international environment.
• Take ownership of mathematical models, simulations and balancing decisions for an expanding portfolio of innovative casino gaming experiences.
• A challenging, rewarding and analytical environment where expertise has a direct impact on products used around the globe.
• Individual learning and professional development opportunities.
• A vibrant, inclusive company culture with global collaboration and diverse communities.
• Corporate fitness activities and additional employee wellbeing programmes.
