Original job description

We are seeking a highly skilled Senior Software Developer - Full Stack to support the development and modernization of backend integration services, healthcare data interfaces, and user preference portals. In this role, you will be responsible for building Java Spring Boot servers that process clinical reports and support data exchange with electronic medical record systems. Working across full-stack layers, you will engineer NextGen Connect (Mirth) message channels, construct HAPI FHIR data structures, implement secure OAuth 2.0 and mTLS authentication protocols, and build ReactJS front-end interfaces to manage pub/sub subscription preferences.

Location: Toronto, ON (Onsite as needed basis)

Duration: 6-month contract.

Advantages
Modern Healthcare Integration Stack: Hands-on engineering using Java Spring Boot, HAPI FHIR (R4/DSTU2), NextGen Connect (Mirth), and ReactJS.

End-to-End Security Focus: Implement industry-standard security protocols, including OAuth 2.0, mTLS, and containerized Docker deployments.

Full-Stack Delivery Scope: Combine backend integration, API development, event-driven pub/sub workflows, and front-end user experience design.

Flexible Onsite Work Model: Enjoy remote flexibility with onsite collaboration in Toronto required only on an as-needed basis.

Responsibilities
Full-Stack Java Application Engineering: Design, build, test, and support Java Spring Boot microservices, REST APIs, and backend integration layers to support clinical data delivery solutions.

FHIR Resource Processing: Implement the HAPI FHIR library to parse, validate, transform, and process FHIR R4 and DSTU2 resources across backend workflows.

Message Channel & Integration Engineering: Build, configure, and maintain NextGen Connect (Mirth) channels to ingest, transform, validate, route, and acknowledge HL7 v2 clinical data streams.

Subscription & Preference Logic: Develop ReactJS user interfaces that enable clinical users to configure data preferences, translating user selections into valid pub/sub subscription filter criteria.

Security & Containerization: Implement secure service-to-service communication using OAuth 2.0, mutual TLS (mTLS), audit logging, and role-based access controls, while packaging services into Docker containers.

Quality Assurance & Testing Automation: Create and execute unit, integration, interface, conformance, and end-to-end regression test suites covering HL7 v2, FHIR, pub/sub, and ReactJS components.

Cross-Functional Collaboration: Partner with architects, UX designers, security leads, QA teams, and external technical partners to define technical specifications, deployment runbooks, and interface mappings.

Qualifications
Public Sector Experience: Prior experience delivering software solutions within a public sector or enterprise healthcare environment (Strictly Required).

Java, Spring Boot & HAPI FHIR: Senior-level hands-on development experience with Java, Spring Boot, REST APIs, and the HAPI FHIR library to process FHIR R4 and DSTU2 resources (Strictly Required).

NextGen Connect (Mirth) & HL7 v2: Demonstrated experience configuring NextGen Connect (Mirth) channels for HL7 v2 message transformation, routing, validation, error handling, and Java service integration (Strictly Required).

ReactJS & Event-Driven Subscriptions: Strong ReactJS development experience building web user interfaces integrated with Java services and translating user preferences into FHIR Subscription filter criteria (Strictly Required).

Secure Delivery & Containerization: Hands-on experience implementing OAuth 2.0, mTLS, audit logging, automated testing, and Docker containerization (Strictly Required).

Nice-to-Have Assets:
Detailed knowledge of clinical report exchange specifications, routing protocols, and acknowledgement workflows.

Experience with FHIR Subscription and SubscriptionTopic concepts, practitioner-based routing, and FHIR profile validation.

Familiarity with automated build, test, container scanning, and deployment CI/CD pipelines.
