What are we building?

At Hard Rock Digital , we’re reimagining what online gaming can be. Backed by the legendary Hard Rock brand—synonymous with music, entertainment, and hospitality - we operate like a bold, fast-moving startup with a passion for delivering unforgettable digital experiences. Now, we’re leveling up.

Our newly formed Games Studio is at the heart of this mission, dedicated to building world-class Card & Table and iCasino games that thrill players and define the next generation of online casino entertainment. You’ll be at the forefront of this journey, leading the creation of in-house Card & Table games for Hard Rock Bet Casino—games that will anchor our content strategy and become flagship experiences for our players. This is your chance to shape something from the ground up, with the backing of a global brand and the freedom of a startup.

Our Games Studio is dedicated to building world-class slot and iCasino games that thrill players and define the next generation of online casino entertainment. As we expand our in-house capabilities, we’re looking for a Senior Game Design Mathematician to help shape the design, core mechanics, features, and mathematical foundations of our slot portfolio. This is a chance to influence the DNA of our games from the ground up—designing models that drive excitement, engagement, and long-term player value.

What’s the position?

As our Senior Game Design Mathematician, you will define and lead the mathematical architecture behind our slot games. From early concept modeling to certification and live tuning, you’ll ensure every title delivers precise statistical integrity, compelling volatility profiles, and strong commercial performance.

You’ll partner across disciplines to convert creative ideas into robust probability structures and feature mechanics — owning the math from theory to implementation. This role requires both deep technical mastery and the ability to influence gameplay design at a strategic level.

Key Responsibilities:

• Design Slot Math Models: Develop mathematical models that define RTP, volatility, hit frequency, and feature behavior aligned with creative and commercial objectives.
• Create & Maintain PAR Sheets: Produce detailed PAR sheets and supporting math documentation for all games.
• Simulate & Validate: Build simulations and perform theoretical calculations (Excel and/or code-based) to validate outcomes and ensure statistical accuracy.
• Debug & Support Implementation: Validate RTP implementation and debug discrepancies in collaboration with engineering teams to ensure correct integration of the math model.
• Prototype & Iterate: Participate in playable prototype creation, playtesting, and iterative tuning of gameplay mechanics to optimize player experience.
• Innovate Game Mechanics: Contribute new mathematical structures and feature concepts that differentiate our slot portfolio.
• Analyze Market & Performance Data: Review competitor math models and post-launch performance data to inform future designs and improve player engagement.
• Support Certification: Provide documentation and technical support through regulatory approvals across US, and CAN regulated markets.
• Work Within Development Pipelines: Collaborate within structured development environments, including simulation tooling and version-controlled workflows.

What are we looking for?

We’re looking for a senior-level slot mathematician who combines deep technical expertise with a passion for creating unforgettable player experiences.

You understand that great slot games are built on exceptional math—and you’re motivated to push boundaries while delivering precision and compliance in regulated markets.

The ideal candidate will have:

• 5+ years of experience designing mathematical models for real-money slot games.
• A proven track record contributing to or leading the math design of multiple shipped slot titles.
• Strong experience creating PAR sheets and detailed math documentation.
• Deep expertise in combinatorics, probability theory, and statistics.
• Advanced proficiency in MS Excel or other tools for complex modeling and simulations.
• Experience working with programming teams and simulation tools (Java, C, C++ or similar).
• Familiarity with version control systems and structured development workflows.
• Experience working with internal and external development teams
• Experience supporting games through regulatory certification processes.
• Bachelor’s degree in mathematics, Computer Science, Statistics, or equivalent experience.
• Strong written and verbal communication skills in English.
• A genuine passion for slot and casino games.
• A sense of humor and a passion for building compelling, high-quality player experiences.

What’s in it for you?
