Introduction text

Schwarz Digits creates the technological foundation for digital sovereignty in Europe. As the IT and digital division of the Schwarz Group, we develop and manage the IT infrastructures for the retail divisions Lidl and Kaufland, as well as Schwarz Production and PreZero. At the same time, we operate as an independent provider in the external market to support companies across Europe in their digital transformation. We bundle our core services in the areas of Cloud, Cyber Security, Data & AI, Communication, and Workspace.

Join us and contribute to digital sovereignty in Europe. With us, you will work at the intersection of agility and security: You will benefit from fast decision-making processes, enjoy genuine creative freedom in your projects, and be able to build upon the stable foundation of the Schwarz Group.

Your tasks

• Product Development & Architecture: You actively shape the architecture and future of our Managed Database Services (e.g., PostgreSQL, MariaDB, Redis) throughout the entire lifecycle. You design robust, scalable, and highly available database solutions within a Kubernetes-based environment.


• Stability & Reliability: As a Lead, you are responsible for maintaining and optimizing the availability of our database infrastructure. You implement SRE practices to ensure fault tolerance and data integrity.


• Automation (DBaaS): You drive the automation of deployment, backup, and patching processes. Your goal is a "self-service" database model controlled via REST APIs (based on Golang).


• Performance & Capacity Planning: You analyze database workloads, optimize queries and configurations, and ensure through proactive planning that our cloud landscape scales according to our customers' needs.


• End-to-End Responsibility: We live by the principle of "You build it, you run it." You accompany your services from the first line of code through release management to incident analysis (postmortems), supported by our internal service teams.


• Technical Mentoring: You lead the team toward technical excellence, share your knowledge of database internals, and support your colleagues in continuously improving their skills in software development and operations.

Your profile

• Passion for Cloud & Data: You are eager to help shape Europe's digital sovereignty and bring deep experience with database technologies in cloud environments.


• Database Expert: You have profound knowledge in the operation and design of relational (e.g., PostgreSQL) and/or NoSQL databases, as well as topics such as high availability, replication, and backup strategies.


• Software Engineering Skills: You are proficient in development with Golang or Python and have experience in building APIs (REST, gRPC) to control infrastructure.


• Container-Native: You are highly familiar with containerized system landscapes, ideally with experience in Kubernetes Operators for database orchestration.


• Automation & Tooling: You are a master of Infrastructure-as-Code (e.g., Terraform, Ansible) and feel at home in the monitoring ecosystem (Prometheus, Grafana).


• Analytical Thinking: Troubleshooting complex performance bottlenecks and processing incidents within the framework of problem management are exciting challenges for you.


• Communication: Your excellent communication skills in German and English enable smooth cooperation within our international, agile teams.
