Short description

We are building a complex, high-load system based on a microservice architecture, where every component plays a critical role. This is not a legacy support project - it's about continuous development of new modules, performance optimization, and high-throughput processing.

You will join the Risk-Management Product Group, which builds and develops the product - risk management tools and the back office pages used by internal risk managers and external operator clients to manage sportsbook risk.

Our team is small, but always growing and focused (6-8 engineers), operating with high autonomy, deep ownership, and a shared passion for scalable engineering.
