Junior Data Engineer

About the role

As a Junior Data Engineer you will help build the data platform that powers AMBOSS. You will work on real production pipelines, dbt models and integrations from your first week, with the support of senior engineers and the Data Platform Lead.

What you'll do

• Build and maintain pipelines for our data platform: dbt models, Airflow DAGs, Airbyte connectors, BigQuery transformations. You will ship to production, not just to a sandbox.
• Contribute to integrations and internal services. Help connect our ERP and other business systems to the platform and contribute code to internal services like our master data management tool.
• Partner with Analysts and Data Scientists to make the platform something they can self-serve from with confidence.
• Use AI with judgment to boost productivity and develop the judgment to know when to trust the output and when to throw it out.
• Work hands-on with senior engineers. Pair on hard problems, get your code reviewed, give code reviews back and grow fast through the loop.
• Learn the business. Sit in stakeholder conversations and understand why a request matters before you build for it.

What you'll need

• Endless curiosity and a questioning mindset about both code and business.
• Comfort with AI tools (Claude or similar) and an instinct to reach for them rather than around them.
• Strong communication skills in English. German is a plus.
• Up to 1 year of previous work experience (internships, side projects or academic work all count).

Nice to have

• SQL fundamentals: writing joins, window functions and CTEs.
• Working Python skills: building a small data tool or script end-to-end.
• Exposure to cloud (GCP, AWS or similar) and modern data tooling (dbt, Airflow or similar).
• Any exposure to CI/CD, Infrastructure as Code, vector databases or integrating with business systems like ERP, Shop or Bank integrations.

What they offer

• 30 paid vacation days, AMBOSS holiday, personal purpose day and more
• Daily healthy breakfast & lunch by in-house chef in Berlin HQ, AMBOSS daycare, work remotely from other office spaces
• Urban Sports Club membership, Fitbit Versa 3, Deutschland Ticket
