We’re looking for a Senior Java Expert with deep experience in microservices architecture to join an Agile development team working on safety-critical, high-impact digital systems.

You’ll help design and implement microservice-based applications that support infrastructure and signalling projects — combining technical excellence, quality, and cybersecurity awareness.

This is a long-term mission for a seasoned engineer who enjoys complex environments, structured methodologies, and collaboration across business and IT.

What You’ll Do

• Design and develop robust back-end components using Java (version 21) and Spring Boot / Spring Data.
• Implement microservices that communicate via REST APIs and JSON, ensuring scalability and maintainability.
• Apply Agile/Scrum practices, collaborating with Java and Angular specialists in a multidisciplinary team.
• Ensure code quality through consistent unit testing using JUnit 5, Mockito, and PowerMock.
• Follow strict documentation and quality standards, supporting compliance with ISO 9001, EN 50.128, and ISO 27001 / NIS.
• Deploy and manage services using OpenShift or Kubernetes, applying best practices for containerized environments.
• Maintain version control and CI/CD workflows with Git and GitLab.
• Automate database versioning through Liquibase or Flyway.
