to clarify requirements and deliver interfaces.

• Maintain interface documentation, data-flow diagrams, deployment procedures, runbooks, and

change records.

• Follow secure development, source-control, peer-review, change-management, privacy, and

regulated healthcare data-handling practices.

• Participate in scheduled releases and an on-call or after-hours support rotation as business needs

require.

Required Qualifications

environment.

• Strong hands-on Java development experience, including debugging, libraries/APIs, data

manipulation, and maintainable coding practices.

• Strong hands-on Lua development experience for healthcare integration, transformation, and

interface logic.

• Production experience building and supporting interfaces in Mirth Connect (NextGen Connect).

• Production experience building and supporting interfaces in iNTERFACEWARE Iguana.

• Strong knowledge of HL7 v2 structure, segments, fields, components, data types,

acknowledgements, and common trigger events.

• Experience with XML, JSON, REST APIs, SQL, relational databases, TCP/IP, MLLP, and secure file

transfer.

• Ability to diagnose interface problems across applications, networks, certificates, databases, and

containers, or CI/CD pipelines.

• Knowledge of interface security, TLS/mTLS, certificates, OAuth 2.0, encryption, auditing, and secrets management.

Understanding of HIPAA, PHI/PII protection, least privilege, data minimization, and secure software

development.

• Relevant certification or formal training in HL7, FHIR, Mirth Connect, Iguana, Java, or healthcare

interoperability.

Success Measures

• Interfaces meet approved functional, security, performance, and reliability requirements.

• Message failures and production incidents are identified, communicated, and resolved within agreed

service levels.

• Code, mappings, tests, deployment records, and operational documentation are complete and

supportable.

• Solutions are reusable, observable, maintainable, and delivered with minimal disruption to customers

and clinical workflows.
