The Role
Designs and validates mathematical models for slot, crash, and instant-win games, including RTP, volatility, paytables, multipliers, jackpots, and house edge. Builds Monte Carlo simulations, analyzes live game performance, verifies RNG and outcome implementations, supports certification with regulators and testing labs, and resolves production issues involving payouts, rounding, and statistical accuracy. Collaborates with Engineering, Design, Legal, Compliance, and QA.
Summary Generated by Built In
We are a product powerhouse building a full-stack ecosystem for iGaming businesses. 40M+ players. 250 brilliant minds. One bet: our technology is so rock-solid that we stake our own business on it.
From our hubs in Ukraine, Georgia, the UK, and the Philippines, we blend real-world experience, a battle-tested Tech Radar, all within an open-door culture.
We invite Game Mathematician to join the VeliPlay team.
VeliPlay is our homegrown game studio — where crash, instant, and real-time mechanics meet bold ideas and sharp execution. Backed by the full power of the VeliTech ecosystem, we built games for today’s players — and tomorrow’s hits.
Here, dev meets design, sound meets strategy, and every sprint is driven by one goal: crafting gameplay that feels alive.
In this role, you will:
Work your way. Remote, hybrid, Kyiv office — find your rhythm.
Level up daily. Real mentorship, a clear career path, and support to lead your product.
Battle-tested tech stack. Work with what we bet on: microservices, serverless, SRE strength.
Health comes first. Insurance and 10 days' sick leave — because your health is a priority.
Time off that matters. 20 days paid vacation, public holidays — to recharge your way.
Build your brand. Share your story, grow your voice — inside and out.
Culture with a pulse. Team offsites, community events, and the energy of people who care.

Here, dev meets design, sound meets strategy, and every sprint is driven by one goal: crafting gameplay that feels alive.
In this role, you will:
- 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.
- Analyze 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.
- 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.
