We are an AWS Services Partner and a Certified Services Partner in Anthropic’s Claude Partner Network. Our commercial focus is DACH and the Gulf region, alongside selected international opportunities. Your role Build the pipelines and data models that people can depend on. You will own defined components of our data engineering projects, from understanding a source system to delivering tested transformations and monitoring how they run. Our data platform engineering work connects operational systems with analytics and AI applications. Depending on the project, you will work with cloud warehouses, lakehouse architectures and the data quality and reliability practices that support production use. What you will do Build Python and SQL pipelines to ingest and transform data from APIs, databases, files or event sources. Develop data models and dbt transformations with clear definitions, tests and documentation. Implement incremental processing, schema checks and reconciliation so changes and data issues are visible. Configure orchestration and monitoring; investigate failed runs and improve recovery and troubleshooting. Contribute to cloud data platform components, infrastructure configuration and deployment workflows. Use Git, pull requests and code review to deliver maintainable changes and explain their impact on downstream users. What you bring Current university enrolment in computer science, data science, business informatics or a related technical discipline. Strong SQL and practical Python, supported by pipelines or data models you have built and maintained for actual users or team workflows. A sound understanding of data modelling, incremental loads, data quality and the operational behaviour of scheduled pipelines. Experience with version control and testing, plus practical exposure to a cloud platform, warehouse or orchestration tool. The ability to own a well-scoped deliverable, investigate problems systematically and communicate clearly in English. Experience with dbt, Airflow, Dagster, AWS, Snowflake, Databricks, BigQuery, Apache Iceberg or Terraform is valuable. You do not need experience with every technology; show us where you have developed depth. What you can expect You will work on data systems with clear users and delivery requirements, collaborate directly with experienced engineers and the founders, and receive substantive code review. Your part-time responsibilities and schedule will be planned around your studies.
