• Enable and maintain punchout catalogs to improve guided buying experiences and ensure accurate supplier enablement.
• Oversee material master-related activities, ensuring data integrity and alignment across systems and processes.
• Maintain and optimize SAP release strategies and approval workflows and Order Management Team, ensuring alignment with governance, controls, and business requirements.
• Collaborate cross-functionally (Procurement, IT, Finance, Operations) to define requirements, resolve issues, and implement scalable system solutions.
• Partner with IT and data teams to support data validation, reconciliation, and testing across system integrations and process flows.
• Document business requirements, process changes, system dependencies, and test scenarios to support system enhancements and operational readiness.
• Provide ongoing system support, issue resolution, and user enablement to increase adoption and system effectiveness.
• Support system improvements across procurement and adjacent platforms (e.g., Fieldglass).

What you'll bring

• Hands-on experience with SAP Ariba (sourcing, guided buying, supplier enablement, contracts).
