Intellias is looking for a Staff Interoperability Engineer to join a large-scale digital healthcare initiative focused on designing, building, and scaling healthcare interoperability solutions that enable secure, standards-compliant health data exchange across the U.S. healthcare ecosystem.
This is a Staff-level Individual Contributor role for an experienced engineer who combines deep expertise in healthcare interoperability, distributed backend systems, API architecture, and cloud-native engineering. You will define technical direction, solve the platform’s most complex interoperability challenges, and establish engineering standards that enable teams to build reliable, scalable, and compliant healthcare integrations.
The role combines deep hands-on engineering with broad technical influence across interoperability architecture, FHIR implementation, API security, healthcare standards, and AI-enabled engineering practices.
Project Overview:




The project is building a FHIR-based healthcare data platform that enables secure interoperability across EHR systems, healthcare providers, payers, national healthcare exchange networks, laboratories, pharmacies, wearable devices, and digital health applications.
The platform processes healthcare data at national scale, supporting Patient Access APIs, Bulk FHIR APIs, Provider Directory APIs, SMART on FHIR, and real-time healthcare integration services while maintaining compliance with U.S. healthcare interoperability standards and regulations.
The engineering environment combines Python, Apache Spark, Kafka, Kubernetes, cloud-native infrastructure, FHIR R4, HL7, REST APIs, OAuth2/OIDC, SMART on FHIR, distributed event-driven architectures, and AI-assisted engineering.
This is an AI-native engineering environment, where coding agents and reusable AI capabilities are used to accelerate implementation, test
