Remote Mongodb Developer Jobs (NOW HIRING)

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. 
Strong expertise in Java 11  (preferably Java 17) and Spring Boot. 
3 years of hands-on FHIR experience (R4 required; R5 preferred). 
Experience with core FHIR resources, profiles, extensions, validation, and versioning. 
Proven experience with HAPI FHIR (server configuration and customization). 
Solid understanding of payer healthcare data domains (member, coverage, claims, benefits). 
Experience implementing OAuth 2.0 / OIDC and SMART on FHIR. 
Hands-on experience with Azure, Kafka (or equivalent), and MongoDB and/or relational databases. 
Experience building and operating cloud-native microservices. 
Strong communication skills and ability to work in regulated environments. 

Preferred Qualifications: 
Experience with Bulk FHIR ($export) and asynchronous workflows. 
Familiarity with X12 transactions (270/271, 834, 835, 837). 
Experience with HL7 v2 or CDA/CCDA. 
Knowledge of terminology services (SNOMED CT, LOINC, RxNorm). 
Experience with API gateways (Azure APIM, Apigee, Kong). 
Familiarity with Infrastructure as Code (Terraform, Bicep). 
Experience with observability tools (Open Telemetry, Prometheus, Grafana). 
Prior experience with CMS/ONC interoperability initiatives or payer programs. 

Success in this role: 
Deliver and operate a production-grade payer FHIR platform covering required resources and operations. 
Improve scalability, latency, and reliability across Kafka-driven pipelines. 
Maintain strong security and compliance posture for PHI. 
Elevate engineering standards through mentorship, documentation, and automation.
