The Role
We are looking for a Senior or Expert Java Developer to design, build, and modernize backend integration components for a core Safekeeping and Corporate Actions platform.

• Work in a Scrum environment (JIRA), filling in the blanks in requirement analysis and test case preparation when bottlenecks occur.
Expectations
•
Experience: Min. 5 years (for Senior) or 10+ years (for Expert) of Java backend development in large-scale enterprise environments.
• Core Stack: Java, Spring Boot, Spring Integration.
• Architecture & Integrations: REST services, microservices, and integration patterns.
• Messaging: Event-driven integration platforms (preferably IBM MQ and Kafka).
• Databases: Strong SQL and relational database knowledge (preferably Oracle).
• DevOps & Testing: Maven, Git, CI/CD pipelines, and automated testing (JUnit, Testcontainers).
• Languages: Fluent English (both written and spoken).
Nice to Have
• Previous experience in banking, trading, custody, settlement, or other regulated domains.
• Familiarity with cloud-ready application design and containerization (Kubernetes).
• Experience modernizing legacy systems or building layers around vendor platforms.
• Practical use of AI-assisted development tools and static code analysis.
What We Offer
• Salary: 140 - 170 PLN / hour (B2B).
