Senior Java Developer (FHIR) – Interoperability (Remote)About this role:

We are seeking a Senior Java Developer with deep HL7® FHIR® expertise to lead the design and implementation of payer-centric interoperability platforms. This role focuses on building secure, scalable FHIR R4 services (with R5 experience as a plus) that expose member, coverage, claims, and clinical data across required FHIR resources and operations. The ideal candidate will work in a cloud-native Microsoft Azure environment, leveraging Kafka-based event streaming and MongoDB to support high-volume, regulatory-driven healthcare data exchange.

This is a hands-on role for a senior engineer with strong experience in enterprise Java/Spring Boot development, payer domain knowledge, and real-world experience operating FHIR at scale in production environments.

About the Company:

We are a technology-driven organization focused on delivering innovative healthcare interoperability solutions. Our teams build scalable, secure platforms that enable seamless data exchange across the healthcare ecosystem while meeting regulatory and compliance requirements.

Responsibilities:

• Design, implement, and maintain FHIR R4 servers and APIs supporting payer-relevant resources and operations (CRUD, search, history, bulk data, subscriptions).

• Define and manage FHIR profiles, extensions, value sets, and terminology bindings aligned with payer use cases.

• Map and transform payer system data (membership, claims, benefits, authorizations) into FHIR-compliant formats.

• Build Java 17 or more/ Spring Boot microservices using clean architecture and domain-driven design principles.

• Develop and integrate RESTful and event-driven APIs using Kafka.

• Implement HAPI FHIR frameworks for persistence, validation, and serialization.

• Apply SMART on FHIR, OAuth 2.0, and OpenID Connect for secure authentication and authorization.

• Ensure HIPAA-compliant handling of PHI, including encryption, audit logging, and access controls.

• Deploy and scale applications in Microsoft Azure using Docker and Kubernetes (AKS).

• Design resilient systems with retries, circuit breakers, idempotency, and DLQs.

• Contribute to CI/CD pipelines and infrastructure-as-code initiatives.

• Establish testing strategies (unit, integration, performance) and observability practices.

• Mentor engineers, conduct code reviews, and contribute to architecture decisions.

Requirements:

• 5 years of professional Java development experience.
