Staff Interoperability Engineer - Healthcare Data

Staff Interoperability Engineer - Healthcare Data Company Overview We're solving one of healthcare's biggest problems: fragmented health data. At b.well, we've built the infrastructure that brings together a person's complete health record—scattered across providers, pharmacies, labs, and apps—into one place. We operate the largest consumer health data platform. Our interoperability infrastructure processes millions of health records daily, connecting to thousands of data sources nationwide. This is where healthcare interoperability happens at scale—connecting health data from EMRs to wearables to pharmacy systems to insurance claims, all in real-time, all FHIR-native, all compliant. The Role We're seeking an exceptional Interoperability Engineer to design, build, and scale cutting-edge health data exchange solutions. This is a hands-on technical role for a seasoned professional who will own complex integration projects end-to-end. You'll build real-time data pipelines connecting thousands of healthcare data sources—enabling seamless, secure, and compliant health data exchange for millions of patients. What You'll Do: Build Large-Scale Interoperability Solutions Design and implement real-time health data exchange solutions supporting millions of patient records Build Patient Access APIs, Provider Directory APIs, and Bulk FHIR APIs (CMS Interoperability Rule compliant) Develop connections to national networks (Carequality, CommonWell, eHealth Exchange, TEFCA) Create scalable data pipelines ingesting from EMRs, HIEs, labs, pharmacies, payers, wearables, and IoT devices Implement FHIR R4 and US Core Implementation Guide across all integration points Solve Complex Technical Challenges
