• Design, develop, and maintain conceptual, logical, and physical data models tailored to business needs, with a strong focus on customer and CRM-related data
• Implement historization techniques such as Slowly Changing Dimensions (SCD-1, SCD-2, etc.) to ensure accurate tracking of data changes over time
• Collaborate with cross-functional teams to translate business requirements into scalable and easy to maintain data structures
• Build and optimize data pipelines and transformation workflows to support data model implementation and data quality
• Ensure data consistency, lineage, and governance across systems and domains
• Continuously improve and refactor existing data models to align with evolving business needs and technical standards
• Contribute to the development of best practices and standards for data modeling and engineering within the team
• Support the data engineers during implementation
• Strong experience in data modeling, including dimensional modeling, normalization / denormalization, and historization strategies
• Solid understanding of data engineering principles and ability to implement data models in production environments
• Hands-on mindset with the ability to design, build, and troubleshoot data solutions end-to-end
• Experience working with large datasets and complex data ecosystems
• Familiarity with modern data platforms and tools (e.g., Snowflake, dbt, GCP, Airflow) is a plus, but not a requirement
• Strong analytical and problem-solving skills, with a keen eye for detail and data quality
• Excellent communication skills and the ability to work collaboratively in cross-functional teams
• Experience in the retail or crm sector is a nice-to-have
• High level of personal responsibility and ability to learn new technologies in a fast-paced environment
• You have good communication and visualization skills
• Flat hierarchies and short decision-making channels
• A family-friendly company culture with flexible working hours and remote working options available according to your individual needs
• Numerous training and further development opportunities within the Group (5% of working time for self-organized training and education)
• A lunch allowance
• Staff shopping and travel discounts
• Extensive workplace wellness programme including fitness classes, massages, etc.
• An industry-standard, attractive and performance based annual gross salary starting at 50.000 Euro (on a full-time basis) with the possibility of higher pay according to experience and qualifications
