| 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.
