Senior Data Engineer (f/d/m)

• Designing, developing, optimizing, and maintaining the data architecture and ELT/ETL pipelines that support our business goals across charging sessions, billing, invoicing, and promotions.

• Build and maintain large-scale batch and streaming pipelines, data warehouse models, and transformation layers that are reliable, performant, and well documented.

• Own the semantic layer that turns physical tables into governed business metrics, so that every team consumes one consistent definition of revenue, margin, usage, and active customers.

• Prepare and structure data so it is AI ready, enabling natural-language analytics, retrieval, and AI-assisted experiences on top of a trusted foundation.

• Become a master of the business domain, not only the data. Understand how charging, billing, settlement, invoicing, and OEM and fleet economics actually work, and let that knowledge drive how you model and expose the data.

• Strong SQL (Snowflake, PostgreSQL) and hands-on experience with dbt or a similar transformation framework.

• Strong Python skills for data engineering, automation, and pipeline orchestration.

• Solid understanding of data modeling (star schema, large flat tables) and how models feed BI and semantic layers.

• Experience building or maintaining a semantic / metrics layer, and a genuine interest in making business data consumable by AI experiences.

• Familiarity with cloud data warehouses, APIs, orchestration (for example Airflow), and version control (Git).

• Comfortable applying software engineering practices: CI/CD, automated testing, code reviews, and monitoring.

• Strong communication and documentation skills, with the ability to work across technical and non-technical teams.
