Work model: Remote, with on-site meetings once a month (Warsaw / Poznań / Kraków)
responsibilities :
The project involves the development and evolution of large-scale backend systems built on a modern microservices architecture. The platform processes high volumes of data in near real time and relies heavily on asynchronous communication and event-driven patterns to ensure scalability, resilience, and fault tolerance. The team is responsible for designing, implementing, and maintaining services that support critical business processes. A strong focus is placed on horizontal scalability, high availability, and performance, as the systems operate under significant load and must remain stable and responsive. You will work closely with Product Owners, analysts, and other engineering teams in a cross-functional environment, taking part in architectural discussions and technical decision-making.
