Senior Game Mathematician

We are looking for an experienced Senior Game Mathematician to take a leading role in developing mathematical models for an in-house slot game portfolio. The position combines advanced game mathematics, statistical modelling, and simulation with the opportunity to influence the technical foundations of math development.

Beyond creating and balancing game mechanics, you will contribute to the evolution of internal simulation tools and mathematical frameworks, working closely with game designers, producers, and engineers.

Responsibilities

• Take full ownership of slot game mathematics, developing models from initial game concepts through balancing, testing, and regulatory certification

• Create and fine-tune mathematical configurations for different slot formats, including reel-based, ways/Megaways, cluster pays, grid games, jackpots, and feature buy mechanics

• Define and optimize key game parameters such as RTP, volatility, hit frequency, maximum win, payout distribution, and bonus contribution, ensuring alignment with gameplay and product objectives

• Develop and adjust reel strips, paytables, symbol distributions, free spins, multipliers, cascades, bonus features, and progressive mechanics, including multiple RTP configurations and ante bet options

• Perform large-scale Monte Carlo simulations, validate theoretical and simulated RTP, and evaluate statistical reliability through variance analysis, confidence intervals, and convergence testing

• Prepare mathematical documentation, including PAR sheets, RTP calculations, and supporting materials required for independent testing and certification

• Contribute to the design and continuous improvement of an internal math development and simulation framework, participating in architectural discussions, technical reviews, and implementation

• Evaluate live game performance data, identify potential improvements, and provide mathematical recommendations for existing and upcoming releases

• Partner with producers, game designers, and developers to assess new mechanics, balance gameplay experience, and address mathematical or technical risks

• Help establish consistent math development standards, share technical knowledge, and support the professional growth of other mathematicians

Requirements

• 5+ years of professional experience in slot game mathematics within a game provider or development studio, rather than an operator

• Track record of at least 10 commercially released slot titles, preferably including games with demonstrated market success

• Extensive knowledge of probability, combinatorics, and statistical modelling, with the ability to apply these principles to complex slot mechanics

• Proven ability to build complete mathematical models around defined targets, including RTP, volatility, hit rate, maximum exposure, payout distribution, and feature contribution

• Practical expertise in balancing different slot formats and mechanics, including Megaways, cluster pays, grid slots, bonus buys, jackpots, free spins, multipliers, and cascading features

• Strong understanding of reel and paytable configuration, bonus buy and ante bet mathematics, and multiple RTP variants, with the ability to balance feature frequency, payout sizes, and overall player experience

• Advanced experience in mathematical validation and high-volume simulations, including analytical RTP verification, Monte Carlo methods involving billions of spins, variance analysis, confidence intervals, and convergence assessment

• Familiarity with gaming certification standards and testing procedures, including requirements associated with GLI, BMM, eCOGRA, iTech Labs, and preparation of mathematical reports and PAR sheets

• Ability to independently manage mathematical development throughout the complete game lifecycle, from initial design to final certification

• Degree in Mathematics, Applied Mathematics, Statistics, Physics, or a related discipline, preferably at Master's level or above

• Previous involvement in building or improving proprietary slot math engines or simulation frameworks

• Knowledge of mathematical optimization techniques, including genetic algorithms, simulated annealing, and linear programming, for automated adjustment of reels and paytables

• Experience designing mathematical models for crash games, instant-win products, or other alternative gaming formats

• Understanding of the interaction between mathematical models, game clients, and backend systems

• Fluent English for technical documentation, collaboration with international stakeholders, and communication with testing laboratories or regulators

• Strong communication skills, with the ability to translate complex mathematical concepts into practical explanations for non-mathematical colleagues

• Willingness and ability to mentor junior and mid-level mathematicians and contribute to knowledge sharing within the team

Would be a plus

• Proficiency in at least one programming language: Python, C++, C#, Rust, Java, or Go

• Experience developing high-performance simulation software, including multithreading, performance optimization, and large-scale data processing

• Familiarity with Git, automated testing, and code review practices, as well as software architecture principles such as modularity, well-defined interfaces, and deterministic simulation results

• Contributions to industry research, professional publications, conferences such as ICE, SiGMA, or G2E, or relevant technical communities

What's in it for you

• Opportunity to contribute to the development of innovative iGaming products and influence key technical decisions

• Work on challenging projects involving advanced game mathematics and simulation technologies

• Opportunities for professional development and career growth

• Collaboration with experienced professionals in a supportive, knowledge-sharing environment
