Tech Lead - Game mathematician

At Aristocrat, we are motivated by our mission to bring happiness to life through the power of play. As a Tech Lead - Game Mathematician, you will play a key role in crafting groundbreaking online casino games that attract millions of players globally. This position places you in an ambitious team that develops world-class gaming products that entertain and stay in sync with mathematical accuracy and global gaming regulations.

This is an outstanding opportunity to build the future of online casino games. You will collaborate closely with game designers, developers, and product managers to develop, validate, and balance mathematical models that guide the player experience. Your expertise in probability theory, RTP modeling, volatility analysis, and regulatory compliance will be essential to our success. Join us in composing the next generation of casino games that will set industry standards!

What You'll Do

• Build and develop complete mathematical frameworks for new casino and iLottery game concepts, including paytables, prize structures, win distributions, and feature mechanics.
• Define and balance core math parameters such as RTP, volatility, hit frequency, maximum win, and bonus contribution percentages to meet both business and player experience targets.
• Build and run Monte Carlo simulations and statistical models to validate game behavior across billions of game rounds.
• Produce comprehensive math specification documents and game math sheets for use by designers, developers, QA, and certification labs.
• Liaise with external certification bodies (e.g., GLI, BMM, eCOGRA) to support regulatory submission and approval of game mathematics.
• Review and verify implemented game logic in-engine to ensure it matches approved math specifications.
• Analyze live game performance data and player metrics to find opportunities for math rebalancing or feature improvement.
• Stay current with evolving gaming regulations across international markets and incorporate compliance requirements into math build.
• Contribute to the development and improvement of internal math tooling, simulation frameworks, and documentation standards.
• Participate in concept reviews and provide mathematical feasibility assessments for proposed game features and mechanics.
• Work collaboratively with global studio teams for status updates and delivery of defined mathematical goals.
