Senior Game Mathematician (iGaming)

Location: Remote

Company

hirify.global develops iGaming products, including in-house slot games and related mathematical and simulation technologies.

What you will do

• Own slot game mathematics from initial concepts through balancing, testing, and regulatory certification.
• Create and fine-tune models for reel-based, ways/Megaways, cluster pays, grid, jackpot, and feature buy formats.
• Define and optimize RTP, volatility, hit frequency, maximum win, payout distribution, bonus contribution, reel strips, paytables, symbols, free spins, multipliers, cascades, and progressive mechanics.
• Run large-scale Monte Carlo simulations, validate theoretical and simulated RTP, and assess variance, confidence intervals, and convergence.
• Prepare PAR sheets, RTP calculations, mathematical reports, and certification materials.
• Improve internal math development and simulation frameworks, evaluate live performance data, collaborate with designers, producers, and engineers, and mentor other mathematicians.

Requirements

• 5+ years of professional experience in slot game mathematics within a game provider or development studio, rather than an operator.
• At least 10 commercially released slot titles.
• Strong knowledge of probability, combinatorics, and statistical modelling, with experience building complete models around RTP, volatility, hit rate, maximum exposure, payout distribution, and feature contribution.
• Practical expertise with Megaways, cluster pays, grid slots, bonus buys, jackpots, free spins, multipliers, cascading features, reel and paytable configuration, ante bets, and multiple RTP variants.
• Advanced experience in analytical RTP verification and high-volume Monte Carlo simulations involving billions of spins, variance analysis, confidence intervals, and convergence assessment.
• Familiarity with gaming certification standards and testing procedures associated with GLI, BMM, eCOGRA, and iTech Labs, including mathematical reports and PAR sheets.
• Ability to manage the complete mathematical development lifecycle from initial design to final certification and understanding of interactions between mathematical models, game clients, and backend systems.
• Degree in Mathematics, Applied Mathematics, Statistics, Physics, or a related discipline, preferably at Master's level or above.
• Experience with proprietary slot math engines or simulation frameworks; knowledge of genetic algorithms, simulated annealing, and linear programming.
• Experience with crash games, instant-win products, or other alternative gaming formats; strong communication skills; fluent English for technical documentation and international collaboration; willingness to mentor junior and mid-level mathematicians.

Nice to have

• Proficiency in Python, C++, C#, Rust, Java, or Go.
• Experience developing high-performance simulation software with multithreading, performance optimization, and large-scale data processing.
• Familiarity with Git, automated testing, code review, modular architecture, well-defined interfaces, and deterministic simulation results.
• Contributions to industry research, professional publications, ICE, SiGMA, G2E, or relevant technical communities.

Culture & Benefits

• Work remotely on innovative iGaming products.
• Contribute to advanced game mathematics and simulation technologies.
• Influence key technical decisions and mathematical development standards.
• Professional development and career growth opportunities.
• Collaborate with experienced professionals in a supportive, knowledge-sharing environment.
