Senior Data Engineer – Berlin (On-Site)
As a Senior Data Engineer, you will play a key role in building the data backbone of mama health’s real-world evidence platform. We use data mining and analytics to systematically map the end-to-end experiences of chronic patients, transforming patient-generated data into structured, high-quality evidence to improve decision-making and patient outcomes.
Your mission
You will work hands-on with data from multiple sources and formats, including event data, operational systems, partner datasets, and unstructured inputs such as free text. You will turn raw inputs into reliable, analytics-ready datasets that power patient journey analysis, product features, and reporting for pharmaceutical partners. This includes building and maintaining pipelines, defining consistent data models, and enabling fast and trustworthy access to data for analytics, product, and AI teams.
You will also contribute to operational excellence by implementing monitoring and quality checks, improving pipeline reliability and performance, and evolving the platform as product and data volume grow. You will work closely with cross-functional stakeholders to translate real-world needs into pragmatic data solutions while maintaining privacy, security, and correctness in a sensitive healthcare context.
Your profile
Required qualifications and experience include:
- Bachelor’s or Master’s degree in Computer Science, Data Engineering, Data Science, or a related field.
- 3+ years (or equivalent) experience in a Data Engineering / Analytics Engineering / backend-leaning data role.
- Strong programming skills in Python and solid SQL skills (joins, window functions, performance basics).
- Solid understanding of ETL/ELT concepts and experience building or maintaining data pipelines (batch and/or streaming).
- Experience with relational databases (e.g. PostgreSQL/MySQL); familiarity with analytical storage (BigQuery/Snowflake/Redshift) is a plus.
- Familiarity with orchestration/transformation tooling (Airflow, dbt, Dagster, Prefect).
- Ability to clean, transform, and validate large datasets, and to implement practical data quality checks.
- Interest or experience in extracting structured signals from unstructured data (free text / conversations).
- Basic experience with monitoring/observability for pipelines (logs, alerts, SLAs) and willingness to own reliability.
- Familiarity with cloud platforms (preferably AWS; GCP/Azure also fine) and containerization (e.g. Docker).
- Knowledge Graph is a plus.
- Good engineering hygiene: Git, code reviews, small frequent commits, tests, CI/CD (appropriate for data systems).
- Strong communication skills and willingness to collaborate with product, analytics, and AI teams.
- Comfortable working in a fast-paced startup environment with iterative delivery.
- This role requires you to be based in Berlin.
