Key Responsibilities

• Design, develop, and maintain backend services using Java 11+ and Spring Boot.
• Write clean, well-tested, and maintainable code with a strong emphasis on unit testing (JUnit, Mockito).
• Work with configuration classes, REST clients, structured logging, and secure service-to-service communication.
• Collaborate closely with team members across modules using Git, Jira, and Confluence.
• Participate in code reviews and follow established CI/CD practices.
• Integrate with MongoDB, SQL databases, and perform basic optimizations.
• Contribute to the deployment process using Maven, Docker, and Kubernetes basics.

Requirements

• 2–4 years of professional experience as a Java Developer.
• Strong knowledge of Java 11+ and Spring Boot.
• Solid understanding of dependency injection, multi-module projects, and component-based architecture.
• Experience with unit testing using JUnit and/or Mockito.
• Familiarity with relational and/or NoSQL databases (SQL, MongoDB).
• Experience with Maven and basic CI/CD pipelines.
• Familiarity with REST APIs and service-to-service authentication.
• Good communication skills and team collaboration mindset.
• Fluency in English (written and spoken).
• EU citizenship or valid work permit in the EU.

You will be a great candidate for us if you:

• Have worked on distributed REST-based systems and understand DTOs, idempotent flows, and validation rules.
• Know or are willing to learn Camunda (BPMN basics, external task workers, REST API).
• Are familiar with observability tools such as Grafana and log aggregation practices.
• Have some exposure to Kafka, OAuth2/OIDC, or secrets rotation in production systems.
• Embrace clean code practices, give/receive feedback, and enjoy working across team boundaries.
