Staff Data Engineer (Emerald)

• As a Staff Data Engineer on the Emerald team, you will play a critical role in shaping the architecture, scalability, and technical direction of H1’s healthcare entity resolution platform. EMERALD is responsible for linking large-scale external healthcare datasets, including PubMed, clinical trials, conferences, ct.gov, and web-collected data to H1’s canonical physician and organization profiles
• This role sits at the intersection of distributed data engineering, entity matching, identity resolution, and large-scale healthcare data processing. You will lead a small team of engineers while remaining deeply hands‑on technically, owning the systems and pipelines powering automatching, grouping logic, identity mapping, deduplication, and enrichment workflows processing tens of millions of records
• You will partner closely with Product, AI/ML, Analytics, and Engineering teams to improve platform accuracy, scalability, reliability, and operational efficiency across one of H1’s most critical data platforms
• Lead the design, optimization, and scalability of distributed Spark/PySpark pipelines powering entity resolution and large-scale healthcare data processing
• Own systems supporting automatching, identity mapping, grouping logic, deduplication, enrichment, and auto‑approval workflows across healthcare provider and organization datasets
• Build and maintain scalable processing frameworks for PubMed, clinical trial, ct.gov, conference, and other healthcare data sources
• Drive infrastructure optimization initiatives focused on improving throughput, runtime, observability, and cloud compute cost efficiency
• Partner closely with AI/ML teams to integrate matching and resolution models into EMERALD and improve matching precision and recall
• Lead complex technical initiatives from architecture and design through deployment, monitoring, and long‑term production support
• Serve as a technical leader and mentor across the team through code reviews, technical guidance, and engineering best practices
• Collaborate directly with Product and business stakeholders to align technical solutions with operational and customer needs
• Support production operations, incident response, troubleshooting, and ongoing platform reliability
