• Own data quality end-to-end: define validation rules, confidence scores, and quality thresholds; build automated monitoring and alerting; identify and resolve issues before they reach users
• Build AI-powered data tooling — entity resolution across duplicate provider records, practitioner-to-organization relationship inference, specialty classification from unstructured data, and quality scoring that quantifies how much you trust a record
• Operate and evolve existing Spark-based pipelines orchestrated by Prefect on AWS, improving reliability, observability, and onboarding speed so new data sources go from raw files to searchable records in days, not weeks
• Establish data governance standards for the provider directory: schemas, staging processes, and refinement workflows that turn messy inputs into trustworthy outputs
• Partner with Analytics to build data quality dashboards and reporting. Partner with Product and Business teams to prioritize which data sources and quality improvements have the highest user impact
• Lead incident response when data issues arise — stale records, broken pipelines, source regressions — and build the observability to catch problems before users do
