Responsibilities

Execute all inventory transactions (receiving, putaway, picking, issuance, returns) in real time through our ERP/MES systems, maintaining greater than 99.9% record accuracy with full lot, serial, and location traceability
Own the daily cycle count program: schedule and execute counts by priority stratification, investigate discrepancies within the same shift, document root causes, and escalate variances to the Inventory Lead

Handle all parts to aerospace FOD, ESD, and contamination-control standards, maintain 5S organization in assigned zones, and store ITAR-controlled material in designated secured areas in compliance with regulatory requirements
Communicate proactively with cross-functional stakeholders: confirming ETAs on part requests, flagging supply issues before they impact production, completing shift handoffs, and proposing process improvements that strengthen inventory control
