The Director I, Legacy Systems Integration & Decommissioning serves as the senior leader responsible for managing the complete lifecycle of legacy application systems during ADUSA's SAP S/4

HANA Retail Spine transformation program. This strategic role owns the critical pathway between existing legacy systems and the new SAP S/4

HANA platform, ensuring seamless continuity of business operations while systematically transitioning from outdated technology infrastructure to modern, cloud-enabled solutions.

Reporting into the ERP Transformation executive leadership structure, this position architects and executes comprehensive strategies for: maintaining and enhancing legacy systems that must integrate with SAP during the transformation, establishing robust test environments and data management frameworks supporting end-to-end testing, orchestrating the systematic decommissioning and retirement of legacy applications post-migration, and preserving historical data in compliance with regulatory requirements while minimizing ongoing technical debt and operational costs.

This leader partners closely with functional tech leads, data migration teams, System Integrator (SI) technical resources, enterprise architecture, infrastructure teams, and legal/compliance stakeholders to ensure legacy systems remain stable and functional throughout the transformation, enable comprehensive testing and validation, and are properly archived and decommissioned following successful cutover to SAP S/4

HANA. The role demands deep technical expertise in legacy application technologies, integration architectures, data management, compliance requirements, and decommissioning methodologies combined with strong program management capabilities to coordinate complex, multi-year transition activities across 20-30+ legacy applications supporting ADUSA's multi-brand retail operations.
