Job Technologies
Your role in the team
- The more challenging the task, the more creative your solution? Then you can make a bigger impact with us than just programming standard applications. With your creativity and an extensive technology stack, you will develop sophisticated and complex applications that are used daily in the companies of the REWE Group:
- You are part of a cross-functional team responsible for all non-pricing aspects of sales campaigns.
- You are responsible for validating innovative ideas, creating prototypes, implementing Test-Driven Development and Continuous Integration, as well as supporting and troubleshooting our applications.
- You ensure that all relevant interfaces are identified, connected, and managed. This includes API management and event-driven integration.
- You not only develop new applications but also modernize our established system landscape together with the team.

Our expectations of you
Education
- A successfully completed degree in Computer Science or Business Informatics, or a comparable course of study, or a completed vocational training with an IT background.
Qualifications
- Primarily, your personality is important to us. We are looking for someone who fits well with us on a human level and is motivated to advance our team. Your very good analytical and conceptual thinking skills, combined with strong communication abilities—especially with colleagues and listeners from non-technical backgrounds—as well as your passion for backend development, form the foundation for this.
- Your knowledge of cloud technologies, preferably Google Cloud (containerization using Docker and Kubernetes).
- Your proficient handling of AI-powered tools in software development (e.g., Claude Code, GitHub CLI, or similar tools).
Experience
- You have several years of professional experience in backend development with Java and Spring Boot (Quarkus is an advantage).
- You have experience with event-driven architectures and messaging technologies, preferably Apache Kafka.
- Your experience with Infrastructure-as-Code and automation (e.g., with GitLab, GitOps, and Terraform).
- Your experience in modernizing established legacy systems (IBM DB2, Host, Java batch processing).
- Ideally, you have some experience with Spec-Driven Development. This is a plus, but not a must.
