This job involves a depth of understanding of the multi-modal RWD ecosystem across Lilly's therapeutic areas to contextualize and drive RWD to the necessary end-user data products by leading the creation of sophisticated data engineering products, creating processes for automation of data ingestion and product creation, and leading special projects for Global Medical Affairs - Health Economics and Outcomes functions and the broader enterprise. Further, this position will be responsible for identifying and advocating standard processes across the data asset lifecycle, working closely with other data domain and analytics leaders. Collaborating closely with multi-functional teams, you will lead the technical implementation of data products, ensuring scalability, reliability, and performance. The ideal candidate possesses deep expertise in data engineering, strong problem-solving skills, and a passion for leveraging data to drive business outcomes.
This position reports to HEOR Central and is embedded within the BIA organization and works in close partnership with HEOR, SDIA, Statisticians, Medical, and Clinical teams.

- Translate analytic, business, and research requirements into reproducible data extraction and transformation logic, supporting cohort construction, temporal logic, and consistent reuse of RWD across teams.
- Apply deep understanding of healthcare data structures and standards when engineering data products, ensuring datasets are fit for purpose for downstream analytics and compliant with scientific, regulatory, and audit expectations.
- Establish and implement standard engineering practices and methodology across the data asset lifecycle, including automated data ingestion, data quality checks, integrity testing, validation, monitoring, alerting, and documentation from source table to analysis-ready output.
- Lead CI/CD pipeline setup, code review, and testing standards, ensuring all transformation code is version-controlled, tested, and deployable in a reproducible manner.
- Collaborate closely with multi-functional partners - data scientists, statisticians, analytics leaders, and other technical teams - to understand business and technical requirements and develop documentation of RWD engineering standards, transformation templates, code list repositories, and pipeline performance guidelines.
- Provide technical consultation to collaborators on appropriate use of data products and underlying RWD assets, including structural limitations of specific data sources, join strategies, and performance considerations; develop source-specific training materials for HEOR scientists, SDIA, and statisticians.
- Develop and implement KPIs to measure system performance, efficiency and pull through to program impact.
- Create an inclusive culture where producing and maintaining high-quality data is a core discipline.
