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.
