We're looking for a Senior Backend Software Developer to lead the migration of a large-scale Java-based monolithic application (WAR on Tomcat) into a modern, containerized environment running on Kubernetes or OpenShift. This role is ideal for a hands-on developer who understands how to refactor traditional Java applications to run efficiently and securely inside containers — while maintaining performance, reliability, and network communication integrity.

Your tasks
  • Analyze an existing monolithic Java/Tomcat application and define the migration strategy toward containerized deployment
  • Refactor code, configurations, and dependencies to make the application container-ready and cloud-native compliant (stateless design, environment variables, configuration management)
  • Optimize the application for scalability and resilience in OpenShift or Kubernetes environments
  • Design and implement inter-process communication mechanisms (including socket-based integrations) in the new architecture
  • Collaborate with DevOps engineers to integrate application containers with CI/CD pipelines and deployment automation
  • Ensure logging, monitoring, and security best practices are embedded in the migrated application
Your profile
  • 5+ years of experience in backend development using Java
  • Strong understanding of Tomcat and traditional Java EE or Spring-based architectures
  • Proven experience migrating applications to containers (Docker, Kubernetes, or OpenShift), as well as Linux, MySQL and troubleshooting distributed applications
  • Deep knowledge of networking concepts and experience working with sockets and low-level communication
  • Familiarity with microservices principles, REST APIs, and inter-service communication
  • Knowledge in Java build tool (Maven/Gradle)
We offer
  • An open and friendly corporate culture characterized by constructive and collaborative interaction
  • We provide you with support for your future plans with a company pension scheme (depending on country-specific circumstances)
  • Early risers and night owls - thanks to a flexible working model you can organise your working day yourself
  • We also support you privately â benefit from special payments or additional vacation days on anniversaries or other special occasions
  • Utimaco is growing and living diversity Our global team includes colleagues from 42 nationalities and 45 different languages spoken
