• Contribute to architecture discussions and technical decisions, writing clean, maintainable code and sharing knowledge across the team

☑️ What you will need

• Professional experience building backend services, ideally in Kotlin and/or Python


• Solid experience designing and building backend services and REST APIs; experience with WebSockets or other real-time streaming protocols such as NATS/JETSTREAM is a plus


• Working knowledge of SQL and experience integrating with multiple internal or third-party services


• An understanding of performance fundamentals — identifying bottlenecks, managing latency, and building systems that stay responsive under load


• Strong problem-solving skills and clear communication with both technical and non-technical colleagues


• Curiosity and enthusiasm for learning new technologies; interest in financial markets or crypto is a plus, not a requirement


• Familiarity with Docker/Kubernetes and cloud environments (AWS) is a plus
