    For one of our clients in the telecommunications industry we are looking for JVM Software Engineer.

    The new joiner will be part of a team focused on modernizing and streamlining legacy Java applications.

    Key responsibilities include:

    • Drive modernization – migrate Java applications from Wildfly to Spring Boot, removing legacy components like EJBs and JMS while simplifying the architecture.
    • Standardize APIs – create and evolve OpenAPI specifications, driving contract-first development and clean service design.
    • Integrate seamlessly – connect systems and processes through Kafka to enable reliable, event-driven communication.
    • Guarantee quality – develop robust integration and regression tests to ensure full functional parity after migration.
    • Build for the cloud – define Kubernetes environment, access controls, and deployment strategies aligned with platform standards.
    • Automate delivery – design and refine CI/CD pipelines that bring speed and stability to every release. And beyond migration:
    • Keep applications continuously up to date using OpenRewrite and Renovate Bot
    • Design and implement AI-based code review systems as an intelligent first gate for code quality and guideline compliance
    • Experiment daily with GitHub Copilot and other AI assistants to accelerate development
    • Explore AI-driven approaches to detect risks and breaking changes during library updates

    Project technology: SpringBoot (the latest), Java 21 (version 8, 11, 17 in the migrated project), JPA, GitHub Copilot, Claude Code, Renovate Bot, OpenRewrite, EJB (as part of a migrated project, just being removed), Camunda, Kubernetes, Kibana, CI/CD (Jenkins), Git, Intellij Idea
