About the Role We are seeking a Senior Software Engineer to join a newly established team that will oversee one of the most specialized and critical sectors in our technological landscape - the Game Engine domain. This role will bridge the gap between engineering, game mathematics, platform, and compliance. You will be responsible for developing, maintaining, and enhancing the tools, frameworks, and services that enable our mathematicians and game teams to design, validate, deploy, and monitor game logic in live environments. This position focuses on deep expertise in a highly specific technical area: game engines, mathematical libraries, simulation data, RTP monitoring, round details, and integrations with both internal and external game development projects. You will be part of a small, knowledgeable team with significant responsibilities. The consequences of this work are immediate: incorrect game logic, incomplete round details, or inaccurate RTP monitoring can impact game release schedules, business performance, and regulatory compliance. If you thrive working with complex domain logic, reviewing technical implementations, understanding game mechanics, and managing systems where precision is crucial - this role will resonate with you.

Key Responsibilities

- Lead, maintain, and advance Playson's Game Engine domain - Work on internal frameworks and libraries used by mathematicians to implement game logic and mathematical libraries. - Review and validate mathematicians' code, ensuring quality, correctness, maintainability, and appropriate use of internal frameworks. - Contribute to the development and support of game engines used to run mathematical logic within our platform. - Assist in integrating with external game studios by helping develop interfaces and bridges between third-party game implementations and Playson's platform. - Handle data structures and protocols that connect game logic with frontend and backend systems. - Participate in RTP monitoring processes, including validating production transaction data against simulation data and expected mathematical behavior. - Support and refine tools used for mathematical review, simulations, data files, monitoring, and alerting. - Implement and maintain round details logic for regulated markets, ensuring accurate provision of detailed game round information to partners and regulators. - Collaborate closely with mathematicians, backend engineers, platform teams, compliance experts, and product representatives. - Engage in code reviews and technical discussions to uphold high engineering standards in the Game Engine domain. - Investigate issues related to game logic, mathematical validation, monitoring, and engine behavior. - Participate in minimal on-call duties related to the systems owned by the team, primarily focusing on monitoring, alerts, and domain-specific incidents. - Take ownership of a highly specialized area where quality, accuracy, and attention to detail are paramount.

Requirements

- Extensive software engineering experience, preferably in backend, game engine, gaming, gambling, betting, or simulation-heavy environments. - Proficiency in Node.js/TypeScript, or strong expertise in another Object-Oriented Programming language such as C++, Java, C#, Go, or Python. - Strong understanding of software architecture, code quality, testing, debugging, and maintainability. - Ability to review complex code and provide clear technical feedback. - Expertise in understanding domain-specific logic and working with technical systems where business rules, mathematics, and engineering intersect. - Strong problem-solving skills and capability to tackle complex, non-standard technical challenges. - Experience managing production systems where reliability, accuracy, and correctness are essential. - Knowledge 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, recognizing that games are the core product and engineering decisions directly affect delivery, quality, and compliance. - Excellent English communication skills suitable for an international work environment.

Nice to Have

- Experience in iGaming, gambling, betting, game development, or casino games. - Background in game engines, mathematical engines, simulation tools, or game logic frameworks. - Proficiency in C++ or experience with legacy C++ systems. - Experience with mathematical models, probability-based systems, simulations, random generators, or RTP-related logic. - Understanding of regulated markets and compliance requirements in iGaming. - Experience with ClickHouse or other analytical/columnar databases. - Knowledge of monitoring, alerting, and production diagnostics. - Experience with AI-assisted code review or automated validation tools. - Familiarity with microservices architecture and distributed systems. - Experience integrating third-party games, external studio products, or wrapper-based solutions. - Ukrainian language skills would be advantageous.

What We Offer

- Competitive Salary: We provide a competitive salary in EUR, subject to annual performance reviews. - Quarterly Bonuses: Enjoy a transparent and systematic quarterly bonus system. - Flexible Schedule: We offer a flexible work schedule to suit your needs. - Remote Work Option: Choose to work from home, providing greater flexibility and comfort. - Medical Insurance: Receive comprehensive medical insurance for you and a significant other. - Financial Support for Life Events: We provide financial support during special life events. - Unlimited Paid Vacation: Enjoy unlimited paid vacation leave. - Unlimited Paid Sick Leave: Take unlimited paid sick leave whenever necessary. - Professional Development: Get reimbursement for professional development courses and training.
