We are seeking a Master Data Management (MDM) Specialist to support both ongoing ERP conversion initiatives and steady-state master data governance in a dynamic, manufacturing-focused environment.

This role is ideal for a business-minded SAP professional who understands how master data drives operational execution - not just how to enter it.

You will partner with business SMEs, technical teams, and data leadership to construct, analyze, migrate, and maintain high-quality master data within SAP S/4HANA.

Depending on experience and business needs, this role will focus on one primary domain:

• Material Management

• Business Partner (Customer/Vendor/Employee)

Our team operates in a hybrid model of recurring conversion waves (every ~90 days) and continuous process improvement initiatives.

This role flexes between implementation-focused work and operational MDM support.
