– Contribute to RTP monitoring processes, including validation of production transaction data against simulation data and expected mathematical behaviour

– Support and evolve tools used for mathematical review, simulations, data files, monitoring, and alerting

– Implement and maintain round details logic required for regulated markets, ensuring that detailed game round information can be correctly provided to partners and regulators

– Collaborate closely with mathematicians, backend engineers, platform teams, compliance stakeholders, and product representatives

– Participate in code reviews and technical discussions to ensure a high engineering standard across the Game Engine domain

– Investigate issues related to game logic, mathematical validation, monitoring, and engine behaviour

– Participate in minimal on-call responsibilities related to the systems owned by the team, mainly around monitoring, alerts, and domain-specific incidents

– Take ownership of a highly specialised area where quality, accuracy, and attention to detail are essential

Mandatory Requirements

– Strong software engineering experience, ideally in backend, game engine, gaming, gambling, betting, or simulation-heavy environments

– Solid experience with Node.js/TypeScript, or strong expertise in another OOP language such as C++, Java, C#, Go, or Python

– Good understanding of software architecture, code quality, testing, debugging, and maintainability

– Experience reviewing complex code and providing clear technical feedback

– Ability to understand domain-specific logic and work with technical systems where business rules, mathematics, and engineering are closely connected

– Strong problem-solving skills and ability to work with complex, non-standard technical challenges

– Experience working with production systems where reliability, accuracy, and correctness are critical

– Understanding of backend systems, APIs, data flows, and service-to-service communication

– Ability to collaborate closely with non-engineering technical experts, especially mathematicians or domain specialists

– Strong ownership mindset and willingness to become a key expert in a narrow but highly important technical domain

– Product-oriented thinking, with an understanding that games are the core product and engineering decisions directly affect delivery, quality, and compliance

– English communication skills sufficient for working in an international environment
