Job summary

Hard Rock Games is seeking a Slot Mathematician to own the math behind our slot games—from design through release and live ops. You will ensure mathematical accuracy, hit targets like RTP and volatility, and support regulatory certification across jurisdictions while collaborating with designers and developers.

You’ll help build and maintain a Java-based suite of simulators and math tools, leveraging AI to prototype ideas while keeping correctness at the core.

Qualifications

• 3+ years designing math models for shipped slot games in regulated environments.
• Skilled in building and analyzing slot models with data tools.
• Proficient in Java, Python, C++, or C#; good with version control (Git).
• Strong grasp of probability, combinatorics, and expected-value analysis.
• Bachelor's degree in Mathematics, Statistics, CS, Engineering, or related field.
• Excellent communication to explain math concepts to designers and regulators.

Responsibilities

• Design and model slot game math: reels, paytables, weights, features, and jackpots.
• Tune models to hit target RTP, hit frequency, and volatility across variants.
• Analyze games using data tools; write simulations for complex games.
• Playtest builds; verify payouts and feature behavior match designs.
• Produce PAR sheets and math docs for internal review and labs (GLI, BMM).
• Support regulatory certification across jurisdictions by answering questions.
• Partner with designers on feature costs in RTP and volatility impact.
• Help build a shared Java codebase of simulators and math tools.
• Collaborate with developers from spec to release to ensure math correctness.
• Leverage AI tools to prototype ideas while maintaining ownership of correctness.

Job description

At Hard Rock Games, we’re not just making games—we’re crafting experiences that connect people, deliver thrills, and celebrate the spirit of Hard Rock. As the social casino gaming arm of Hard Rock Digital, our teams shape every stage of the journey from concept to launch to live operations, giving our teams the ability to innovate, experiment, and make real impact. With the backing of a globally recognized brand, we combine the agility of a startup with the reach of an entertainment powerhouse. Here, creativity thrives, ideas scale, and careers grow.

We’re looking for passionate creators, builders, and innovators to join us in shaping the future of free-to- play gaming. Let’s play hard.

What’s the position?

Hard Rock Games is hiring a Slot Mathematician to design, model, and validate the math behind our slot games across our game portfolio. You will own the mathematical correctness of every game - from design through player-facing release - ensuring models meet target performance metrics and regulatory requirements.

Key Responsibilities

• Design and model slot game math: reel strips, paytables, symbol weights, bonus features, free spins, and jackpots.
• Tune models to hit target RTP, hit frequency, and volatility, including multiple RTP variants.
• Analyze simpler games directly using data analysis tools; write and validate simulations in code for more complex games.
• Playtest game builds and verify that implemented games match the designed model, payouts, and feature behavior.
• Produce PAR sheets and comprehensive math documentation for internal review and certification labs (GLI, BMM).
• Support regulatory certification across jurisdictions by answering lab and regulator questions.
• Partner with game designers early, advising on feature costs in RTP and impact on volatility.
• Help build a shared Java codebase of simulators, model libraries and math tools, starting from our existing tools.
• Work closely with developers from specification through release to ensure correct math implementation.
• Leverage AI tools to prototype ideas, generate code, and explore possibilities - while maintaining full ownership of correctness.

What are we looking for?

• 3+ years designing math models for slot games with shipped titles in iGaming, Social, or Land- Based environments. Experience in a regulated environment is preferred.
• Ability to build and analyze slot models directly using data analysis tools - comfortable performing direct mathematical analysis.
• Strong programming and problem-solving skills; Java preferred, but solid Python, C++, or C# is welcome.
• Comfort with version control systems like Git and working in shared code repositories.
• Strong grasp of probability, combinatorics, and expected-value analysis.
• Ability to manually verify, derive, and explain math results. You understand why a model is correct, not just that it runs.
• Bachelor's degree in Mathematics, Statistics, Computer Science, Engineering, or a related quantitative field.
• Clear communication skills - explaining math concepts to designers, producers, and regulators.

What’s in it for you?

Make a visible impact: you’ll own campaigns and events that shape how millions play. Fast-paced execution + brand heritage: build boldly under the Hard Rock name.

• Competitive compensation with flexible vacation and hybrid work.
• Be part of a player-obsessed, inclusive team that trusts your autonomy and skills.
• Influence product strategies, your post-mortems and insights will steer our roadmaps.
