Track B — Assure and Magistral

Responsibilities may include:

• Medication incident and near-miss reporting workflows.
• Province-specific data fields, validation and configurations.
• ISMP Canada NIDR/AIMS integration, subject to vendor onboarding and approval.
• API mapping, submission testing, response handling and reconciliation.
• CQI meeting management.
• Corrective and preventive action tracking.
• Staff competency assessments.
• Pharmacy self-assessment functionality.
• Compounding master formulas, version control and preparation records.
• Ingredient inventory, lot tracking, expiration dates and equipment records.
• Compounding documentation, calculations and PDF generation.

Both tracks share common architecture, authentication, databases and infrastructure.

6. Healthcare Security and Privacy Requirements

Because ZeeNovo processes sensitive health information, candidates must understand secure software development.

Required capabilities:

• Authentication, MFA and secure session management.
• Role-based and resource-level authorization.
• Encryption in transit and at rest.
• Secure API access and input validation.
• Protection against SQL injection, XSS, CSRF and common OWASP vulnerabilities.
• Secure file uploads and document access.
• Audit logs for access, modifications and workflow activities.
• Tenant isolation and testing against unauthorized cross-pharmacy access.
• Secure handling of application credentials, secrets and tokens.
• Backup, recovery and incident investigation practices.
• Protection against automated registration abuse and API misuse.
• Preventing patient information from appearing in development logs, error reports or unapproved third-party tools.

Developers are expected to help ZeeNovo implement technical safeguards appropriate to applicable Canadian privacy requirements, including Ontario's PHIPA and PIPEDA where applicable.

Production patient data must not be copied to personal computers, unmanaged development environments or unauthorized AI services.

Access to production systems must follow company authorization and least-privilege policies.

7. Software Quality and Engineering Standards

Developers must follow a disciplined engineering process:

• Clean, maintainable, modular code.
• Reusable components and shared services.
• Meaningful unit and integration tests.
• Regression testing for existing workflows.
• Secure code reviews.
• Documented database migrations.
• Version-controlled repositories.
• Protected production branches.
• Separate development, staging and production environments.
• Testing before release and verification after deployment.
• Release notes, technical documentation and rollback plans.
• Root-cause analysis for recurring production incidents.

Every significant feature should include its implementation, appropriate testing, documentation and deployment considerations.

8. Additional Technical Skills — Preferred

The following are advantageous but not mandatory:

• TypeScript in React and Node.js applications.
• Docker and container-based deployments.
• AWS ECS, Lambda, SQS and Step Functions.
• GitHub Actions or comparable CI/CD pipelines.
• Redis, caching and asynchronous processing.
• Automated UI testing using Playwright or Cypress.
• Healthcare interoperability experience, including HL7/FHIR concepts.
• Background in electronic health records, pharmacy software or healthcare SaaS.
• PDF generation, electronic signatures and document automation.
• Experience with AI APIs, structured LLM outputs and retrieval systems.
• Python for backend automation or document-processing services.
• Familiarity with Windows desktop applications, Electron or C#/.NET.

Experience with these technologies is useful for future platform development, but demonstrated expertise in the current production stack is more important.

9. Future AI and Automation Development

ZeeNovo is exploring future AI-assisted pharmacy workflow technology, including ZeeNovo Laminar.

Potential work includes:

• Structured prescription and document intake.
• Data extraction and validation.
• Workflow orchestration and background tasks.
• Secure connectors to pharmacy management systems.
• Controlled desktop automation using Windows accessibility technologies.
• AI-assisted clinical and operational recommendations.
• Human approval, independent verification and comprehensive audit trails.

This is a future development direction, not the initial position's primary responsibility.

Experience with agentic systems, AI integrations or Windows services is an advantage.

Developers must understand that AI systems cannot independently make final pharmacist clinical decisions or receive unrestricted access to patient records or pharmacy management systems.
