We are seeking a hands-on Healthcare Interoperability Software Engineer to implement customer integrations connecting dermatology imaging devices, on-premise software, and cloud platforms with hospital and clinical IT environments.
The role combines software development, healthcare interoperability, and customer-facing implementation. Working closely with Solution Architects and Project Management, translating agreed solution designs into reliable, tested, and operational integrations - from technical discovery through implementation, commissioning, and support handover.
Key Responsibilities:
Translate customer workflows and architecture specifications into interface designs, data mappings, implementation tasks, and acceptance criteria.
Develop and configure interfaces for patient demographics, orders, worklists, imaging data, diagnostic results, and reports.
Implement DICOM connectivity and DICOMweb interfaces where required, including integration with local and cloud-based PACS.
Build HL7 v2 message processing and FHIR API integrations, including validation, transformation, routing, acknowledgements, and error handling.
Apply relevant IHE profiles and transactions to agreed clinical workflows; support interoperability testing against customer requirements.
Develop backend services, adapters, and APIs connecting imaging devices, local gateways, clinical applications, and AWS services.
Implement reliable asynchronous processing, retries, duplicate prevention, audit logging, and recovery from connectivity interruptions.
Collaborate directly with customer IT teams and integration vendors on interface configuration, connectivity, troubleshooting, and deployment.
Execute end-to-end integration testing, support customer acceptance and go-live, and resolve technical issues through stabilization.
Maintain interface specifications, deployment instructions, test evidence, and operational support documentation.
Required skills:
Typically 5+ years of software engineering experience, including substantial hands-on delivery of healthcare integration projects.
Proven implementation experience with DICOM, HL7 v2, and FHIR, with deep expertise in at least two and practical working knowledge of the third.
Experience integrating with EHR/EMR and PACS systems, including clinical workflow analysis, patient and encounter identification, and reconciliation of inconsistent data.
Practical understanding of IHE integration profiles, including how actors and transactions translate into implementation and testing requirements.
Strong backend development skills: C#/.NET, Java, Python, or TypeScript.
Experience with REST APIs, JSON/XML, SQL databases, automated testing, Git, CI/CD, and containerized deployments.
Hands-on AWS experience, particularly application integration, secure access, monitoring, and deployment; relevant services may include S3, IAM, Lambda, ECS/EKS, API Gateway, SQS, and CloudWatch.
Working knowledge of hybrid connectivity, TLS, certificates, VPNs, firewalls, OAuth 2.0/OIDC, and secure handling of patient data.
Experience delivering customer projects in healthcare or another regulated software environment.
