Interoperability SME

We are seeking a hands-on Technical SME with deep implementation experience in FHIR-based healthcare interoperability.

This role goes beyond consulting — you will architect, build, and validate FHIR integrations using SDK-level code across one or more languages (Python, .NET, Java, etc.), directly driving the evolution of our client's EHR connectivity solutions.
Understands clinical workflows, has written production-grade FHIR code, and can bridge the gap between standards specifications and working software.

Responsibilities -
• Design, develop, and maintain FHIR-based integrations using SDKs such as HAPI FHIR (Java), firely-net-sdk (.NET), or fhir-py / Google FHIR (Python).
• Write and review production-quality code for FHIR resource creation, parsing, validation, and transformation (STU3, R4, R4B).
• Implement SMART on FHIR authorization flows, CDS Hooks, and Bulk Data Access in real-world integration environments.
• Build and maintain FHIR capability statements, profiles (StructureDefinitions), valuesets, and implementation guides using tools like Forge, SUSHI/FSH, or IG Publisher.
• Lead technical discovery sessions with EHR vendors and IT stakeholders to define FHIR endpoint capabilities, data mapping schemas, and API versioning constraints.
• Communicate complex technical FHIR constraints to non-technical clinical stakeholders.
• Architect and implement abstraction layers or 'FHIR Facades' to ensure integration logic remains EHR-agnostic and scalable across diverse clinical environments.
• Implement and debug EHR-to-payer and EHR-to-HIN integrations across major platforms (Epic, Cerner/Oracle Health, Athenahealth, Veradigm), leveraging platform-specific FHIR APIs and sandbox environments.

Technologies & Skillsets
• FHIR SDKs: HAPI FHIR, firely-net-sdk, fhir.resources (Python), Google FHIR
• Languages: Java, Python, C#/.NET (one or more required)

• Networks: Carequality, CommonWell, Surescripts, eHealth Exchange
• Tooling: SUSHI/FSH, Forge, Simplifier.net, FHIR Validator, Touchstone, Postman
