Core Responsibilities

Primary Functions

Develop, maintain, and continuously refine weekly and monthly inventory forecasts using historical sales, seasonality adjustments, promotional calendars, lead times, and statistical forecasting techniques to minimize stockouts and reduce excess inventory.
Own the cycle count program end-to-end: define count frequencies, generate count schedules, coordinate warehouse teams, investigate discrepancies, post corrections in ERP, and report accuracy improvements to stakeholders.
Analyze daily inventory positions and reconcile inventory ledger versus physical counts to identify root causes for variances, then implement corrective action plans and update standard operating procedures accordingly.
Manage and optimize safety stock parameters and reorder points across SKUs and distribution locations using service-level targets, demand variability, and supplier lead-time analysis to improve fill rates and reduce holding costs.
Execute replenishment planning by generating and validating automated purchase/transfer recommendations from MRP/ERP systems (SAP, Oracle, NetSuite, or similar), adjusting for minimum order quantities, packaging constraints, and promotional events.
Prepare and deliver regular KPI dashboards and executive reports (inventory turns, days of inventory on hand, fill rate, stockouts, excess & obsolete inventory) using Excel, Power BI, or Tableau to inform sourcing, finance, and operations decisions.
Perform SKU-level profitability and aging analyses to identify slow-moving and obsolete stock, create mitigation plans (liquidation, bundling, markdown strategies), and collaborate with category management to implement sell-through tactics.
Partner with procurement and suppliers to reduce lead time variability, expedite critical replenishments when needed, negotiate improved terms, and reconcile supplier-delivered quantities against purchase orders.
Lead root cause investigations into stockouts, overstock situations, shipment discrepancies, and damaged inventory; produce corrective actions and follow-up to prevent recurrence across receiving, putaway, picking, and shipping processes.
Maintain master data accuracy for SKUs, including units of measure, BOM components, bin locations, replenishment rules, and lead times; coordinate updates with IT and ERP data governance teams.
Support month-end and year-end inventory valuation processes by coordinating cycle count results, reconciling perpetual inventory with general ledger, and facilitating audit requests from finance and external auditors.
Configure, test, and validate ERP/MRP settings and system-generated replenishment logic during system upgrades or new module rollouts; act as subject-matter expert for inventory modules and demand planning tools.
Build and maintain demand models that incorporate promotions, new product introductions, and cannibalization impacts; partner with marketing and sales to ingest forward-looking inputs and improve forecast accuracy.
Design and implement inventory segmentation (ABC/XYZ) to tailor control policies and counting frequency based on value, variability, and criticality.
Coordinate inbound and outbound inventory workflows with warehouse operations to optimize picking, putaway, and slotting decisions that improve space utilization and reduce handling time.
Drive cross-functional S&OP processes by presenting inventory implications of demand and supply scenarios, supporting decision-making for promotions, production schedules, and procurement commitments.
Create and implement continuous improvement projects (5S, Kaizen, lean inventory programs) to reduce cycle time for replenishment, improve stock accuracy, and streamline inventory transactions.
Support product lifecycle transitions by managing phased inventory reductions, returns to vendor, or rework actions in coordination with product, quality, and finance teams.
Conduct ad-hoc analyses for pricing, promotions, new product introductions, and seasonal planning to quantify inventory impacts and recommend mitigations.
Monitor and manage KPI-based vendor performance for on-time in-full (OTIF), lead time adherence, and delivered quantity accuracy; recommend supplier corrective actions or alternative sourcing as required.
Train and mentor warehouse and junior inventory staff on inventory control best practices, system transactions, and proper handling to improve data quality and operational compliance.
Implement and maintain safety and compliance protocols for inventory storage (hazmat, temperature control, serialized goods) and support recall or lot-traceability actions when required.
Collaborate with IT to automate manual inventory workflows, improve data integration (EDI/API), and develop operational dashboards that reduce time spent on manual reconciliations.
Quantify and report inventory carrying costs, working capital impacts, and forecast error metrics to Finance and senior leadership to drive capital-efficient inventory strategies.
Lead inventory-related projects such as cycle counting technology rollouts, barcode/RFID implementations, and slotting optimization initiatives from requirements through to user acceptance testing and deployment.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Assist procurement and logistics teams during supplier or transportation disruptions to identify alternate supply or redistribution strategies.
Provide surge support during peak seasons (promotions, holidays) to ensure inventory levels and fulfilment SLAs are met.
Help create and maintain standard operational documentation, training materials, and process maps for inventory-related activities.
Participate in internal and external inventory audits and support audit remediation plans.
