Job Description

Position Overview

As a Senior Backend Developer, you will be responsible for designing, developing, and maintaining scalable backend systems and services. You will work on high-performance, distributed architectures supporting real-time applications. Experience with game servers, Remote Gaming Servers (RGS), or slot game engines will be considered a strong advantage.

You will contribute to building robust backend platforms that handle real-time data processing, player/session management, transactional systems, and third-party integrations, while ensuring scalability, reliability, and performance.
