What are you working on?

- The name of the project(s): VeliPlay
- Genres: Casino
- Platforms: Browser, Mobile

For which tasks (responsibilities)?

- Design and develop mathematical models for slot and crash games, including RTP, volatility, hit frequency, paytables, reel strips, multiplier curves, and house edge.

- Model and balance game features such as free spins, multipliers, Hold & Win, jackpots, Buy Feature, and cash-out mechanics.

- Tune RTP and volatility according to business, market, operator, and regulatory requirements.

- Develop Monte Carlo simulation tools to validate game mathematics across millions or billions of rounds.

- Ensure crash-game models and crash-point generation are statistically sound and provably fair where applicable.

- Work with developers to verify correct math model, RNG, and outcome logic implementation.

- Prepare mathematical documentation and support game certification with testing labs and regulators.

- Analyse live game performance, including RTP, hit rates, and crash-point distribution.

- Investigate and resolve math-related production issues, including payout, RTP, rounding, and edge-case errors.

What kind of professional are we looking for?

- Strong foundation in probability, statistics, combinatorics, distributions, expected value and variance.

- Experience in slot and crash game mathematics: reel strips, symbol weighting, paytables, feature frequency, multiplier/growth curves and house edge.

- Proficient in Monte Carlo simulations and mathematical modeling using Python and/or C#.

- Ability to visualize mathematical models and progressions in Python using libraries such as Matplotlib,



including data preparation, charts and clear annotations of key stages.

- Knowledge of RNG and provably-fair mechanisms, including hash-based seeds, HMAC and verification.

- Comfortable with Excel/Google Sheets and basic SQL for modeling and game/player data analysis.

- 2–4 years of experience as a Game Mathematician, Quant, or similar, ideally with slots, crash or instant-win games.

- Familiarity with UKGC, MGA, Curaçao and other gaming certification requirements.

- Understanding of real-money/FinTech requirements, including transaction integrity, auditability and financial accuracy.

- Strong analytical, problem-solving and communication skills; able to explain complex mathematical concepts visually and to non-technical stakeholders.

- Comfortable working cross-functionally with Engineering, Design, Legal/Compliance and QA.
