Company Overview

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.

Our AI Hub develops and operates innovative, large-scale Computer Vision solutions. Our core architecture is already up and running, built on a robust cloud-native infrastructure:

• Orchestration & Deployment: Kubernetes, Argo CD, and Argo Workflows for complex ETL and model training pipelines.
• Data & Storage: PostgreSQL for metadata repository and S3 Object Storage for large-scale image data.
• Infrastructure: Cloud-native environments (GCP, Azure, or StackIT), managed via Terraform.

Your primary mission will be to support the stability, monitoring, and ongoing maintenance of this existing platform, ensuring smooth daily operations.
