HL7 Integration Engineer at Andishi

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.

Key Responsibilities


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Review existing Mirth Connect and BridgeLink configurations and identify redundant, outdated, or inefficient channels.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.


Required Qualifications


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:
