Position overview

We are looking for a Senior Data Engineer to build and operate a clinical data platform on Databricks, with a strong focus on robust data pipelines, data models, and data quality.

Technology stack

The platform is built on Databricks (Spark, Delta Lake) and includes reusable pipelines, a shared data model, and automated data quality checks.

Responsibilities

• Design, build, and maintain end-to-end Databricks data pipelines (ingestion, transformation, publishing) for production use

• Work with data models (staging, curated, canonical, or dimensional) and help evolve them together with architects and analysts

• Embed data quality and data governance rules into all pipelines (checks, validation, monitoring, alerting)

• Optimize Databricks jobs for performance and cost (cluster configuration, partitioning, caching, file layout)

• Collaborate with data architects, analysts, and domain experts to clarify requirements and refine technical solutions

Requirements

• 5+ years of experience in data engineering, DWH, or big data, including production data pipelines

• Strong hands-on experience with Databricks: Spark (PySpark/Scala), Delta Lake, Databricks Jobs / Workflows

• Proven experience designing and operating end-to-end pipelines on Databricks for batch or near-real-time data

• Experience with data pipelines and CI/CD for data

• Practical experience with data modeling (layered models, canonical or dimensional models) for analytics and reporting

• Experience embedding data quality and data governance rules into pipelines (schema checks, business rules, SLOs, monitoring)

• Good communication skills, upper-intermediate or higher English proficiency, and the ability to work closely with stakeholders in distributed teams and communicate directly with clients

Nice to have

• Experience designing and delivering PoC solutions on Databricks to quickly validate ideas using real data

• Experience with ontologies or a semantic layer (business concepts, metrics, mappings) on top of analytical data
