FHIR Technical SME - Remote

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.

The ideal candidate is an engineer-first practitioner who understands clinical workflows, has written production-grade FHIR code, and can bridge the gap between standards specifications and working software.

• 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 (Structure Definitions), 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.
• Engineer touchless prior authorization (ePA) workflows via Da Vinci implementation guides (PAS, DTR, CRD), translating HL7 specs into deployable integration code.
• Develop integration test suites, FHIR validators, and conformance testing pipelines to ensure standards compliance across environments.
• Partner with engineering teams to translate clinical and business requirements into FHIR-based technical specifications, API contracts, and data flow diagrams.
• Oversee technical connectivity strategy with HIEs and national networks (Carequality, Common Well, Surescripts), contributing to both design and implementation.
• Collaborate with Product teams to assess feasibility of interoperability features, providing SDK-level effort estimates and identifying standards gaps.
• Mentor junior engineers on FHIR concepts, SDK usage patterns, and healthcare data modeling best practices.

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