Master Data Specialist — Material Master & EWM

The Opportunity

Master Data Specialist is personally responsible for executing material master cleanup waves across HV Service, active service materials, and other archetypes, with primary focus on EWM physical attribute remediation in Phase 1 and the field-level data quality rulebook across all material views. The role requires deep end-to-end working knowledge of master data — not just material — because every change to a material master ripples into procurement (info records, source lists), sales (MVKE, pricing), warehouse (EWM handling units), and finance (MBEW valuation). The right candidate diagnoses cross-domain impact before executing, runs the mass updates personally, validates the result, and closes the gate.

How You’ll Make An Impact

• Personally execute Phase 1 EWM physical attribute remediation (dimensions, weight, handling unit data) on active warehouse parts.
• Run cleanup waves on HV Service (~17,000 records) and active service materials (~15,000 records) material master's across MARA, MARC, MVKE, MBEW, MARM, MLAN.
• Build and operate Process Runner and Precisely Automate Studio templates with archetype-specific rules embedded; manage simulation, error handling, and rollback.
• Execute mass updates via MASS, MDG_SW, MM01 / MM02 / MM06; reconcile pre- and post-state via SE16N, MMBE, MB52.
• Maintain the Defect Register for material domain; feed coverage %, defect rate, and cycle-time inputs into the KPI Dashboard.
• Sign off Exit Gate Checklists at the three Definition of Done levels (minimum / target / aspirational).
• Archive obsolete materials via SARA per the program archiving policy.
• Hand off sustainment patterns to BAU once a wave clears target DOD.
• Responsible to ensure compliance with applicable external and internal regulations, procedures, and guidelines.
• Living Hitachi Energy’s core values of safety and integrity, which means taking responsibility for your own actions while caring for your colleagues and the business
