Requirements and Your Profile

• Several years of experience in Java backend development and confident use of SpringBoot.
• Solid knowledge of relational databases, ideally including Oracle and PL/SQL.
• Understanding of modern infrastructure and architecture concepts, including containerized environments and cloud contexts.
• Genuine interest in AI-Driven Development and enjoyment in putting new tools and ways of working into practice, rather than just talking about them.
• A clear, open communication style and a desire to share knowledge within the team.
• Self-directed, structured work in an environment with a lot of scope for design.

Your Responsibilities

• Work on a central integration and middleware layer that cleanly connects our existing ERP with modern services and standard solutions.
• Develop scalable REST APIs and microservices based on Java and SpringBoot to gradually transform a grown ERP architecture into a more modular, service-oriented structure.

• Contribute to architecture and technology decisions as well as the further development of our platform stack.
• Support the establishment of an AI-First working method: AI tools like Cursor, Claude Code, and agent-based development approaches should become an integral part of our future workflow – you help to introduce and further develop this practice meaningfully.
• Design services and interfaces with a view to future AI-based automations and intelligent business processes.
