Job description

We are currently looking for a Senior Java Developer to join one of our long-term public sector projects for a European Institution. You will contribute to a large-scale, high-visibility platform designed for performance, availability, and scalability, handling a significant volume of documents in a distributed, cloud-based environment.

THE WORK:

  • Design, develop, and maintain distributed applications using Java 17, Spring, Elasticsearch and Liferay DXP.

HERE’S WHAT YOU’LL NEED:

  • Strong background in Java (preferably Java 17), Spring Framework, and REST API development.
  • Experience with Elasticsearch and integrating it into applications is a plus.
  • Familiarity with Kubernetes and cloud platforms, with a preference for Azure.
  • Good understanding of PostgreSQL and distributed architectures.
