Profile Overview

We are currently undergoing a full platform transformation from a legacy data center to a modern cloud-based architecture. As our new Data Engineer, you will play a critical role in this greenfield migration (not lift-and-shift) and help shape the foundation for scalable and reliable data infrastructure. You will ensure our current data flows(Kafka, Airflow, Dremio, SQL) are understood, stabilized, and partly redesigned. This is a technical and analytical role with significant responsibility for reliable, reproducible, and on-time data processing and delivery. It is an exciting opportunity to drive meaningful technical change in a collaborative, high-responsibility environment.

Your responsibilities

Data modeling & calculation, maintain and optimize existing ETL jobs and reporting pipelines (Kafka, Airflow, SQL, Dremio)
Design and implement scalable, cloud-native data processing workflows
Conduct rigorous data validation and quality assurance across critical systems
Document and verify data calculation logic for auditability and reproducibility
Collaborate closely with Product, Dev, and Customer Success to ensure data delivery aligns with stakeholder needs
Contribute to the definition and implementation of GDPR-compliant, future-proof data architectures
Play a key role in the transition from legacy systems to the new cloud environment

What You bring to the table

3–5+ years of experience in data engineering, ideally in cloud migration contexts
Strong skills in Python and SQL; experience with Dremio, Pandas, and Jupyter a plus
Proven hands-on experience with Kafka, Airflow, and Linux shell scripting
Familiarity with cloud-native platforms (e.g., AWS S3, BigQuery, Glue)
Understanding of CI/CD tools (e.g., GitLab, Ansible, Docker)
Detail-oriented, quality-focused, and self-driven with strong documentation habits
Working proficiency in German (B2 at least, mandatory), comfortable working in bilingual teams
