This position is full-time and has been approved for work in a primarily remote capacity. Responsibilities - Serve as the client-side senior authority on SAP data migration; face off to the System Integrator's data lead as a technical peer. - Review and challenge the SI's data migration approach and push back where the approach carries unnecessary risk, cost, or downstream operational burden. - Advise the program on migration architecture decisions specific to greenfield S/4HANA from non-SAP sources (Oracle EBS, JD Edwards, PeopleSoft, custom systems), including source-to-target data model translation and legacy-concept-to-SAP-concept mapping. - Advise on tooling selection when the SI's approach is still open and evaluate trade-offs on fit, cost, timeline, and regulated-industry auditability. - Provide hands-on coordination and delivery. - Own day-to-day execution coordination of the client-side data workstream across all domains. - Keep the migration task plan current, flag slippage early, and drive resolution. - Serve as the daily point of contact with the SI's data migration team; track integrator deliverables and escalate delays. - Run regular working sessions with client data owners and the integrator's team; chase open actions, decisions, and deliverables between meetings. - Set and monitor cleansing standards across data domains against agreed quality thresholds; validate that the SI's quality criteria are fit for S/4HANA go-live. - Coordinate with business data owners to keep cleansing on schedule; unblock issues with the right people rather than deferring upward. - Surface data quality risks the SI may not flag (missing legacy concepts, silent data loss in transformation, dependencies across domains) before they become critical. - Organize and track mock load cycles across all domains. - Review reconciliation results independently of the SI. - Ensure business teams complete validation tasks within cycle windows and that findings are actioned. - Ensure data migration activities comply with the organization's data classification policy and applicable regulatory requirements throughout extraction, staging, transformation, and load. - Maintain the data migration cutover plan; coordinate extraction and load scheduling with the SI and technical teams. - Prepare data readiness inputs for go/no-go decisions and provide informed, independent risk assessment to program leadership. - Support hyper care on data-related issues post go-live. - Support migration status reporting and RAID logging for program leadership.
