- Senior test guidance experience for complex healthcare integration or enterprise application programs, including test strategy, planning, estimation, risk-based coverage, traceability, defect management, reporting, exit criteria, and release recommendations.

- Strong API automation experience testing publish-and-subscribe and asynchronous workflows using Postman, NextGen API testing tools, and ngrok, including callbacks, authentication, correlation, idempotency, retries, duplicate events, error handling, and replay.

- Hands-on FHIR and REST testing experience, including FHIR Subscription, SubscriptionTopic, notification Bundles, filters, lifecycle and status changes, resource validation, positive and negative scenarios, and end-to-end API verification.

- Hands-on HL7 v2 and NextGen Connect testing experience, including message structure, transformations, routing, acknowledgements, error paths, interface validation, and end-to-end integration with FHIR and application services.

Responsibilities:

- Develop and maintain the overall test strategy, master test plan, estimates, scope, test levels, environments, data needs, entry and exit criteria, and reporting approach for Enterprise Pub/Sub application changes.

- Review product, workflow, interface, and technical requirements; identify quality risks and coverage gaps; and maintain traceability from requirements through test scenarios, defects, and release evidence.

- Design, automate, execute, and maintain API tests for publishers, subscription management, notification delivery, event retrieval, queue-based processing, downstream actions, and failure-recovery workflows.

- Use Postman, NextGen API testing tools, and ngrok-hosted endpoints to validate REST APIs, external callbacks,



rest-hook delivery, request and response payloads, headers, authentication, timeouts, and error handling.

- Validate FHIR Subscription, SubscriptionTopic, notification Bundles, filters, lifecycle and status transitions, resource references, search and event retrieval, conformance, and positive and negative API scenarios.

- Test HL7 v2 interfaces and NextGen Connect channels, including message construction, parsing, transformation, routing, acknowledgements, invalid messages, interface errors, recovery, and integration with FHIR and application workflows.

- Coordinate end-to-end testing across healthcare applications, Ontario digital health assets, eReferral workflows, publishers, Enterprise Pub/Sub, subscribers, and downstream systems.

- Validate asynchronous reliability and operational scenarios, including event correlation, ordering where required, concurrency, idempotency, retries, duplicate delivery, dead-letter handling, replay, reconciliation, outage recovery, and monitoring.

- Coordinate test environments, endpoint configuration, connectivity, certificates, test accounts, test data, privacy-secure data handling, stubs, simulators, and dependencies across participating teams and vendors.

- Lead defect triage, root-cause collaboration, retesting, regression selection, quality metrics, daily status reporting, risk escalation,



and evidence-based assessment of residual risk.

- Prepare test completion reports and release recommendations, support business acceptance and production validation, confirm operational readiness, and provide testing knowledge transfer to The Agency teams.

Desired Skills:

- Experience testing FHIR R4 or R4B resources and APIs, including Subscription, SubscriptionTopic, event notification Bundles, validation profiles, terminology, and conformance requirements.

- Experience with Ontario digital health services, healthcare assets, EMR or HIS integration, clinical workflows, eReferral applications, and multi-organization testing.

- Experience with NextGen Connect administration and API capabilities, Postman collections, NextGen API testing tools, ngrok, service virtualization, stubs, and test-data utilities.

- Experience integrating automated API and user-interface tests into build and deployment pipelines, with versioned test assets, repeatable execution, reporting, and regression gates.

- Experience testing cloud-based event services, queues, observability, security controls, performance, resilience, failure recovery, and production support scenarios.

- Senior test guidance experience for complex healthcare integration or enterprise application programs, including strategy, planning, estimation, risk-based coverage, traceability, defect management, reporting, exit criteria, and release recommendations.

- Publish-and-subscribe API automation experience using Postman, NextGen API testing tools, and ngrok, including subscription workflows, callbacks, asynchronous events, authentication, correlation, idempotency, ret
