Senior Data Engineer – Clinical & Healthcare Data Overview

We are seeking a Senior Data Engineer with deep experience working with clinical and real-world healthcare data. This role will focus on building and scaling data pipelines that support analytics, research, and downstream machine learning use cases. The ideal candidate has hands‑on experience with OMOP, Databricks, and modern data stacks, and understands the real‑world challenges of clinical data harmonization across disparate sources.

• Design, build, and maintain scalable data pipelines for large, complex clinical datasets (EHR, pathology, genomics, etc.) and implement and manage data transformations and analytics workflows using Databricks (Spark, Delta Lake)
• Ingest, standardize, and harmonize healthcare data into OMOP Common Data Model
• Partner with clinical, analytics, and ML teams to ensure data is reliable, well‑documented, and fit for downstream use
• Lead data quality, validation, and observability efforts for clinical data pipelines
• Develop data models and schemas that support analytics, research, and ML use cases
• Optimize performance, cost, and reliability across the data platform
• Contribute to best practices around data governance, versioning, lineage, and reproducibility
• Take data analysis requirements from commercial customers and map to clinical variables from the OMOP, Epic, or other data models

• 5+ years of experience as a Data Engineer, with significant experience in healthcare or life sciences
• Strong hands‑on experience with Databricks (Spark SQL, PySpark, Delta Lake)
• Deep understanding of OMOP CDM, including:
  • Standard vocabularies (SNOMED, LOINC, RxNorm, ICD, CPT)
  • ETL patterns for clinical data mapping and normalization

• Proficiency in Python and SQL
• Experience with modern data stacks, including:
  • Cloud data warehouses or lake houses (Databricks, Snowflake, Big Query, Redshift)
  • Orchestration tools (Airflow, Dagster, Prefect)
  • Data transformation frameworks (dbt or equivalent)
• Strong data modeling and analytics engineering skills

• Experience working with real‑world evidence (RWE), clinical research, or regulatory‑facing datasets
• Familiarity with ML or feature engineering pipelines built on clinical data
• Experience supporting downstream LLM, NLP, or ML workloads using healthcare data
• Knowledge of healthcare data standards beyond OMOP (FHIR, HL7)
• Experience operating data systems in HIPAA‑compliant environments
