Role Overview
As a Data Engineer at Kleinanzeigen, you will work directly with product managers, analysts, and domain stakeholders to understand what decisions the data needs to support, design and build data assets that are homogeneous with the existing stack, and maintain the full lifecycle of data ingestion, transformation, and quality.
What You Will Do
You will implement dbt models across the medallion architecture, build and maintain Airflow DAGs, and design sensor logic for pipeline dependencies. You will also integrate new data sources, work with data in the right format for each layer, and write dbt tests to catch data quality issues.
Why It Might Be a Fit
You will be a great fit if you are proactive, generous with knowledge, and a team builder. You should have a quality-first mindset enabled by AI, and be able to define the what and why with precision, using AI to handle the how.

- Hands-on production experience with dbt across the medallion architecture

- Proficiency in Python and shell scripting for pipeline development, ingestion tasks, and operational tooling
- Solid understanding of lakehouse concepts and data formats: Delta Lake for ACID-compliant storage, Parquet for columnar efficiency, and Avro for event-driven schema definition
- Ability to work independently, owning tickets from design through delivery, including incident response and backfills
- Ability to gather requirements from non-technical stakeholders, understand consumption patterns, and translate business needs into data models that are accurate, maintainable, and cost-effective
