Java Backend Developer - Krakow

We are looking for an experienced Backend Java Engineer to join a high-performing engineering team delivering scalable, distributed systems within a modern cloud environment. This role combines hands-on development with technical leadership and architectural input.

What you’ll be doing:

• Designing and building robust backend services using Java and the Spring ecosystem
• Leading technical delivery: shaping solutions, refining requirements, and supporting less experienced engineers
• Developing microservices-based architectures, including API-first design and event-driven communication
• Improving system performance through optimisation, refactoring, and memory tuning
• Contributing to CI/CD pipelines and engineering best practices across cloud-native environments
• Working with relational and NoSQL databases, ensuring data integrity and scalability
• Driving clean code, testing standards, and maintainable system design

What we’re looking for:

• Strong commercial experience building backend systems with Java and Spring
• Previous experience providing technical leadership or mentoring within engineering teams
• Solid understanding of distributed systems, microservices, and API design principles
• Hands-on experience with CI/CD, containerisation, and cloud-based deployments
• Good knowledge of build and version control tooling (e.g. Maven/Gradle, Git workflows)
• Experience with messaging systems and asynchronous processing (e.g. Kafka or similar)
• Understanding of database design, transactions, and consistency models
• Familiarity with Agile delivery environments and associated tooling
• Exposure to modern developer productivity tools, including AI-assisted coding, is beneficial

This is an opportunity to work on complex, large-scale systems in a collaborative and forward-thinking environment, where engineering quality and continuous improvement are valued.
