We’re working with an established international iGaming business that develops online slot games across regulated markets globally. The business is now investing in the next generation of its game-engine technology, with a focus on modernising the underlying architecture, improving mathematical validation and building a new slot game engine from the ground up. This hire will play a key role in shaping that next engine and the technical direction of the platform. You’ll join a small specialist team alongside another Game Engine Engineer and a Game Mathematician, with significant ownership across architecture, mathematical validation and delivery. What you’ll be doing * Designing and building a new slot game engine from scratch * Owning game-engine projects end to end * Working closely with mathematicians to turn mathematical models into production software * Building simulations to validate game behaviour and expected outcomes * Working with RTP, RNG,



probability models and payout logic * Comparing production data against simulations and expected mathematical behaviour * Investigating discrepancies and improving engine architecture * Helping define the technical direction of future game-engine development What they’re looking for * Strong software engineering experience * Proven experience building or owning game-engine, simulation-engine or similarly complex backend systems * Ideally, experience building engine technology from scratch * Strong understanding of mathematical or probability-driven systems * Experience with simulations, RTP, RNG, probability or payout mechanics * High ownership and evidence of delivering complex projects end to end * Ability to work closely with mathematicians and translate mathematical requirements into reliable software * Direct experience within slots, casino or iGaming is highly desirable The technology stack is C++. This is not a Unity, Unreal, graphics or gameplay-development role. The focus is on the underlying engine responsible
