Job Responsibilities

S&OP Process Leadership

• Design, implement and own a monthly S&OP process, including data gathering, demand review, supply review, pre-S&OP reconciliation and the executive S&OP meeting.

• Establish the S&OP calendar, meeting charters, roles and responsibilities, and escalation process.

• Lead a rolling 18–24 month planning horizon at the product family level, with SKU-level detail in the near term.

• Develop scenario plans (upside, downside, capacity constraints) and quantify the impact on revenue, margin and inventory.

• Align the S&OP volume plan with the annual operating plan and monthly financial forecast in partnership with Finance.

Demand Planning Support

• Support the development of statistical baseline forecasts by SKU, location and product family, accounting for seasonality and market drivers.

• Support the consensus demand review with Sales, Marketing and Product Management, incorporating promotions, large projects, new products and phase-outs.

• Help measure and improve forecast accuracy and bias by product family, customer and region.

• Support new product introductions and end-of-life transitions within the demand plan.

Supply Planning Support

• Support the translation of the approved demand plan into feasible production, procurement and distribution plans across facilities.

• Support rough-cut capacity planning by plant and line, identifying constraints and resolution options in advance.

• Support the master production schedule and maintain the planning parameters that drive material and purchase requirements.

• Partner with Procurement on supplier capacity, lead times and long-lead material commitments.

Run Strategy & Economic Order Quantities

• Develop a run strategy for every SKU, defining how often and in what quantity each item is produced or purchased.

• Calculate economic order quantities (EOQ) and economic production quantities using demand, setup/order cost and carrying cost.

• Convert run quantities into production cycles and sequences (e.g., product wheels) that minimize changeovers and fit available capacity.

• Review and update run strategy inputs regularly as demand, setup times and costs change.

Inventory Optimization & Safety Stock

• Classify SKUs using ABC analysis based on revenue or volume contribution, refreshed on a regular cadence.

• Calculate safety stock mathematically using demand variability, forecast error, lead time variability and target service levels by ABC class.

• Set reorder points and min/max levels in the ERP system based on these calculations.

• Reduce excess and obsolete inventory while protecting service to customers.

Financial Forecasting

• Convert the unit-based demand and supply plan into a financial forecast covering revenue, cost of goods sold, margin and inventory value.

• Apply pricing, product mix, standard costs and freight assumptions to translate volume into dollars.

• Reconcile the S&OP financial view with the annual operating plan and monthly forecasts in partnership with FP&A.

• Highlight gaps to plan and quantify the financial impact of demand, supply and inventory scenarios.

Network Analysis

• Analyze the manufacturing and distribution network to determine the best sourcing and production location for each SKU.

• Model plant capacity, freight costs, lead times and customer service to support make, buy and stocking decisions.

• Evaluate network scenarios such as capacity additions, line moves, new distribution points and consolidations.

• Recommend network changes that lower total landed cost while maintaining service levels.

Performance Monitoring & Reporting

• Develop and maintain dashboards to track key measures: forecast accuracy, inventory (lbs) and excess and obsolete inventory.

• Present findings, risks and recommendations to senior leadership through the monthly S&OP cycle.

Leadership & Continuous Improvement

• Coach and support demand and supply planners on S&OP tools and best practices.

• Partner with Sales, Manufacturing, Finance, Procurement and Logistics to embed planning discipline across the business.

• Drive improvements in planning tools, ERP capabilities and processes.

• Perform other related duties as assigned.

Job Requirements

• Bachelor’s degree in Finance, Supply Chain, Business, Industrial Engineering, or related field (master’s or MBA preferred).

• Minimum of 4 years of experience in supply chain planning, S&OP, or a related finance or operations role; leadership experience preferred.

• Proven experience designing and running an S&OP or Integrated Business Planning (IBP) process.

• Hands-on experience with demand forecasting, supply planning and master production scheduling.

• Strong working knowledge of EOQ, statistical safety stock and ABC inventory analysis.

• Advanced Excel skills; experience with ERP (SAP, Oracle, JD Edwards or similar) and planning or BI tools.

• APICS/ASCM certification (CPIM or CSCP) and Lean Six Sigma experience preferred.

• Experience in building products or manufacturing with seasonal demand preferred.

• Excellent analytical, communication, and leadership skills.

• Ability to travel up to 25% annually.
