Senior Data Engineer

You have 5+ years of experience in data engineering, ideally with at least 2 years working in healthcare or life sciences, including direct exposure to EHR or claims datasets.

You have experience with ontologies and biomedical schemas (e.g. UMLS, LOINC, ICD9/10, MeSH) and understand the modalities found within RWD — billing claims, lab results, visit notes.

You're fluent in SQL and Python, and you've built and maintained production-grade pipelines that support analytics or scientific workflows.

You have experience building longitudinal patient cohorts from EHR or claims data, including index date logic, washout periods, and follow-up window construction.

You have a solid understanding of the causal inference frameworks such as potential outcomes and target trial emulation.

You have working familiarity with real-world evidence study design concepts—such as active comparator new user designs, time-to-event outcomes, confounder adjustment, and causal discovery algorithms—sufficient to partner effectively with Data Scientists on causal inference workflows.

You value clarity, documentation, and structured thinking—especially when working with complex healthcare data.

You have hands-on expertise with modern data infrastructure, such as Snowflake, dbt, and Dagster.

You can balance upfront design with speed to execution, slowing down when it counts without getting stuck in the details.

Bonus: You've worked in regulated or privacy-sensitive data environments and are familiar with governance models for PHI or sensitive data.

Bonus: You have prior experience working with commercial RWD vendors (e.g. Truveta, Optum, Komodo, IQVIA) and understand the nuances of licensed claims and EHR datasets, including longitudinal patient journey construction and line-of-therapy sequencing.
