About the Role

As Data Engineer on our Healthcare Platform, you will own the foundational data ingestion, entity-resolution, and platform infrastructure end-to-end. You will design and operate scalable batch/streaming data pipelines, harden platform orchestration, and ensure system reliability, security, and cost efficiency.

A central challenge of this role is building and operationalizing our unified healthcare data ontology —a consistent semantic model covering hospitals, departments, specialties, metrics, and classification standards.

Working closely with Analytics Engineers, Data Scientists, and Methodology experts, you will turn heterogeneous, multi-country hospital data into a coherent, highly queryable data asset.
