HL7 Integration Engineer

This is a hands-on engineering role. The engineer should be comfortable entering a complex legacy environment, discovering how existing integrations operate, documenting undocumented workflows, and independently developing a practical migration plan.

• Perform a complete assessment of the existing HL7 integration environment, including approximately eight HL7 engine instances and their connected facilities.
• Inventory and document HL7 channels, interfaces, endpoints, message types, transformations, routing rules, dependencies, and failure-handling processes.
• Work closely with existing engineering staff to capture historical system knowledge and convert it into maintainable technical documentation and runbooks.
• Review existing Mirth Connect and BridgeLink configurations and identify redundant, outdated, or inefficient channels.
• Develop a strategy to consolidate HL7 transformations currently performed at edge locations into a centralized HL7 hub.
• Design and support HL7 workflows associated with a new cloud-based PACS platform.
• Support the consolidation of multiple PACS environments into a single modern PACS architecture.
• Design event-driven HL7 workflows to maintain synchronization between PACS and clinical systems and reduce risks such as duplicate radiology reads.
• Configure and troubleshoot HL7 V2 interfaces, including common ADT, ORM, ORU, SIU, and related message workflows.
• Build and modify Mirth channels, filters, mappings, routing logic, and JavaScript transformations.
• Troubleshoot message failures, interface delays, duplicate messages, incorrect mappings, connectivity problems, and downstream processing issues.
• Support DICOM and radiology integration workflows involving DCM4CHE, DICOM routers, PACS, RIS, and related imaging systems.
• Participate in migration planning, testing, validation, cutover, rollback planning, and production support.
• Assist with moving integration services from a fragile data-center environment into AWS or Azure.
• Provide regular technical status updates, risk assessments, architecture documentation, and implementation recommendations.
• Work independently for extended periods while coordinating closely with engineering, clinical operations, vendors, and leadership.

• Strong hands-on experience with HL7 V2 healthcare integrations.
• Production experience with Mirth Connect / NextGen Connect.
• Experience with BridgeLink or similar healthcare interface engines.
• Strong understanding of HL7 segments, fields, data types, message routing, transformations, acknowledgments, and error handling.
• Experience auditing and cleaning up existing HL7 environments.
• Experience designing or maintaining complex healthcare data flows across multiple facilities.
• Experience with JavaScript transformations inside Mirth.
• Working knowledge of SQL for troubleshooting, validation, and data analysis.
• Experience creating interface documentation, architecture diagrams, dependency maps, and operational runbooks.
• Ability to independently investigate undocumented legacy integrations.
• Strong troubleshooting and root-cause analysis skills.
• Ability to communicate clearly with both technical engineers and non-technical healthcare operations teams.
• Radiology / DICOM Experience: Candidates should have practical exposure to radiology integration workflows. Experience with the following is strongly preferred.
