## Description

We're a team of healthcare IT experts solving real-world interoperability problems, and we're looking for a driven, curious engineer who wants to help modernize how health data moves. As our Integration Engineer for FHIR & Cloud-Native Architecture, you'll design, build, and maintain the pipelines that power secure, scalable data exchange across our ecosystem - combining AWS-native services, Google Cloud Healthcare API, BigQuery, and Mirth Connect. You'll be a driving force behind our FHIR-first strategy, working hands-on with FHIR APIs, transaction bundles, and SMART on FHIR applications while ensuring everything we build meets industry standards and regulatory requirements.

What You'll Do

FHIR Interoperability & API Development

 * Design, build, and deploy FHIR API endpoints; process FHIR bundles and support SMART on FHIR integrations
 * Ensure full compliance with HL7 FHIR standards and current interoperability mandates

Cloud-Native Data Pipelines

 * Architect and maintain serverless, event-driven pipelines using AWS services (Lambda, SQS, API Gateway, Glue, AWS HealthLake) and GCP infrastructure (Google Cloud Healthcare FHIR API, BigQuery)

Core Integration & Maintenance

 * Apply deep Mirth Connect and traditional HIE expertise alongside modern cloud services to troubleshoot complex integrations, optimize performance, and safeguard data integrity

Backend Development & Scripting

 * Write clean, reliable backend code and data transformations in Node.js, JavaScript, and Java across Mirth Connect channels and serverless functions

Data Storage & Management

 * Design and maintain relational data structures in PostgreSQL; optimize analytical query performance in BigQuery

Incident Response

 * Respond to service degradations, outages, and API latency issues; triage and resolve root causes across hybrid on-prem/cloud environments

Testing & Validation

 * Rigorously test and validate FHIR profiles, API payloads, and data exchange workflows for accuracy, reliability, and security

Documentation & Collaboration

 * Document API endpoints, data mappings, and cloud architecture in JIRA, Confluence, and SharePoint; partner closely with cross-functional teams, project managers, and clinical stakeholders

Compliance & Security

 * Uphold HIPAA and healthcare cybersecurity standards, including encryption, identity management, and OAuth2/SMART-on-FHIR authorization frameworks
