- Design secure data integration patterns across multiple security classifications and operating environments.
- Specify API-based, file-based, legacy, and bespoke integration approaches for source-system onboarding.
- Define conceptual, logical, and physical data models, including data flows, data domains, and data ownership considerations.
- Specify Apache NiFi architecture patterns, flow standards, interface contracts, and reusable ingestion components.
- Define governance, metadata, lineage, auditability, security monitoring, and data quality requirements.
- Produce High Level Designs, Low Level Design principles, Architecture Decision Records, and design assurance material.
- Define non-functional requirements for performance, resilience, observability, scalability, security, and maintainability.
- Support assurance, accreditation, and security review activities with architecture evidence and design rationale.
- Provide technical governance and design oversight during build, test, assurance, and handover.
