playson - Senior Software Engineer (Game Engine)
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. • Experience in iGaming, gambling, betting, game development, or casino games. • Experience working with game engines, mathematical engines, simulation tools, or game logic frameworks. • Background in C++ or experience working 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. • Experience with monitoring, alerting, and production diagnostics. • Experience with AI-assisted code review or automated validation tools. • Knowledge of microservices architecture and distributed systems. • Familiarity with Kafka, gRPC, Kubernetes, or AWS. • Experience integrating third-party games, external studio products, or wrapper-based solutions. • Ukrainian language skills would be a plus.
Responsibilities
