Role Purpose
Own the application and integration architecture, migration, and cutover for the spin-off. Ensure systems and data are separated from the parent entity in a controlled, auditable manner, with no dependency surprises at cutover.

Key Responsibilities

Define the target-state application and integration architecture for the new entity (including SaaS, on-premises, and cloud mix, environments, naming conventions, tenant strategy, and logging/monitoring standards).
Map current-state dependencies across the legacy and shared landscape, encompassing shared services, databases, integrations, hosting, and identities.
Determine separation patterns per system (such as clone, carve-out, re-platform, replace, or retire) and integration patterns (including API gateway, ETL, and file exchange).
Build and govern the system inventory, integration catalogue, and technical decision record (TDR), enforcing standards via change control.
Direct the application migration factory, managing data extraction, transformation, reconciliation, and validation strategies, alongside non-functional requirements and acceptance criteria.
Coordinate SIT/UAT and regression/performance testing where required in collaboration with business owners (Finance, HR, Student Services, etc.).
Plan and execute cutover strategies for applications and interfaces, managing freeze windows, delta loads, final reconciliation, and rollback procedures.
Manage SaaS and enterprise application vendors regarding subscriptions, license transfers, and new services, while planning the decommissioning of legacy components post-cutover.
Produce and socialize target architecture diagrams, dependency maps, and integration designs with Infrastructure and Security leads.

Must-Have Spin-Off Experience

Successfully led at least two end-to-end IT carve-outs, spin-offs, or separations covering application and integration streams, including data migration and cutover.
Demonstrable success in preventing "hidden dependency" issues at cutover and sustaining integrations post go-live.

Deliverables

Target application and integration architecture.
Dependency maps and integration catalogue.
Migration runbooks.
Test plans and results.
Reconciliation reports.
Decommission checklist.
