Hiring process
As part of H1’s hiring process, all candidates are required to participate in an in-person final interview. Depending on your location, this may require travel.
About the role
Data Engineering is responsible for the development and delivery of our most important asset - our data. Looking across thousands of data sources from across the globe, the data engineering team is responsible for making sense out of that data to create the world’s most extensive and comprehensive knowledge base of healthcare stakeholders and the ecosystem they influence. It is our job to ensure that only accurate, normalized data flows through to our customers, and at a velocity that keeps up with the changes in the real world. As we rapidly expand the markets we serve and the breadth and depth of data we want to collect for our customers, the team must grow and scale to meet that demand.
WHAT YOU’LL DO AT H1
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.
You will:
•
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.
ABOUT YOU
You are an experienced data engineer with deep expertise building and optimizing distributed data systems in cloud-native environments. You thrive solving complex scalability and performance challenges across high-volume data processing systems and enjoy operating in highly technical, fast-paced engineering environments.
