LOCATIONS: Remote within the EU, with occasional on-site attendance in Luxembourg (approximately 5 working days per year)

Key Responsibilities

• Gather and clarify business requirements and analyse existing processes and applications.

• Design, develop, and support Java / Angular applications and microservices.

• Build and maintain backend services using Spring, Spring Boot, JPA, and Hibernate.

• Develop Angular frontends and integrate them with backend APIs.

• Write and maintain automated unit and integration tests.

• Execute system, integration, and performance testing and support UAT.

• Support release preparation, deployment, and change-management activities.

• Participate in Agile ceremonies and communicate directly with stakeholders.

• Maintain technical documentation, code documentation, and operational guides.

• Strong knowledge of SQL, relational databases, XML, YAML, and JSON.

• Experience with microservices and modern application delivery practices.

• Experience using AI coding agents such as GitHub Copilot, Claude Code, or Codex for implementation, modification, review, or testing - not only code completion.
