Job Technologies
Your role in the team
- As part of our cross-functional product team, you will develop our solutions from conception to stable operation as a Software Engineer with an additional focus on Solution Engineering. In this role, you will collaboratively design and evaluate technical solution and architecture options with the team.
- You assume technical responsibility: For complex issues, you act as a sparring partner for the team and adjacent areas, structuring problem statements and evaluating solution options. For our mission-critical 24/7 systems, you continuously develop monitoring, performance, resilience, and operational capability.
- You will further develop our backend systems: you will design, implement, and operate modern backend services with Kotlin and Spring Boot, and sustainably expand our microservice landscape. In doing so, you will keep interfaces, dependencies, as well as scalability, resilience, and maintainability in focus.
- You connect systems and data: You integrate internal and external applications via APIs and event-driven communication with Kafka. For sustainable data management, you work with PostgreSQL and manage schema changes in a structured manner using Liquibase.
- You develop cloud-native solutions: You design and operate our applications with Kubernetes in Google Cloud and continuously improve our GitLab CI/CD, build, test, and deployment processes together with the team.
- You focus on quality and security: By implementing automated tests, code reviews, and continuous refactoring, you ensure high software quality. You consider authentication and authorization from the outset and work with concepts such as Identity Providers and SSO of the REWE Group.
- You develop our technical future: You bring your experience in technical standards and best practices, share your knowledge with colleagues, and evaluate new technologies and approaches together with the team — including modern AI-powered development tools and Agentic Engineering.

Our expectations of you
Education
- Your experience and qualifications: You have many years of professional experience in software development and have taken responsibility for complex applications, technical solutions, and architectural decisions. You hold a degree in computer science, business informatics, a comparable qualification, or have equivalent extensive practical experience.
Qualifications
- First and foremost, your personality: You convince through initiative, a sense of responsibility, and a structured, solution-oriented work approach. You question existing approaches, bring in your own ideas, and enjoy developing sustainable solutions together as a team.
- Your quality and security standards: Automated testing, clean code, code reviews, and continuous refactoring are a matter of course for you.
- Your perspective beyond the horizon: You want to actively shape not only implementation but also technical contexts, integrations, and architecture decisions, while keeping long-term technical quality and professional benefits in mind.
- Your communication skills: You can convey complex technical contexts understandably, justify decisions transparently, and share your knowledge within the team. You enjoy working in agile, cross-functional teams and communicate confidently in German as well as proficiently in English.
Experience
- Your backend and architecture expertise: You have solid practical experience with Kotlin and Spring Boot as well as with microservice and distributed architectures. You can analyze complex systems, dependencies, and interfaces, and evaluate solution options in terms of maintainability, scalability, resilience, and operability. You already have experience in solution engineering, software architecture, or a comparable role.
- Your experience with integration and data: You are familiar with Kafka or comparable event streaming technologies and the challenges of event-driven systems. Additionally, you are confident in working with relational databases such as PostgreSQL and schema migrations using Liquibase.
- Your Cloud and DevOps experience: You have solid experience with Kubernetes, cloud-native applications, and CI/CD processes, ideally on the Google Cloud Platform. You are familiar with GitLab CI/CD as well as automated build, test, and deployment processes.
