Senior Demand Planner

M-D Building Products•Oklahoma City, OK

About The Position

The Senior Demand Planner owns demand accuracy and integrity across the S&OP process. This person is the primary demand-side point of contact for S&OP communications with the sales organization and is accountable for the statistical forecast, forecast adjustments, and other demand drivers, most notably safety stock, that feed the monthly S&OP cycle.

Requirements

Bachelor's degree in supply chain, statistics, data science, applied math, or a related field.
5+ years of experience in demand planning or forecasting, with demonstrated ownership of forecasting within a formal S&OP or IBP process.
A track record of having built and executed a successful S&OP demand plan in a prior role — not just exposure to the process.
Extensive, hands-on experience in forecasting and related quantitative disciplines: statistics, time-series methods, and data science techniques.
Strong data skills: advanced Excel and SQL required; experience with a demand planning/forecasting platform (e.g., SAP IBP, Kinaxis, o9, Blue Yonder) and, ideally, Python or R for forecast modeling.
Exceptional communication skills, with the ability to explain forecast assumptions, changes, and risk to sales and executive stakeholders in plain terms.

Nice To Haves

APICS/ASCM certification (CPIM or CSCP).
Experience with statistical or machine-learning-based forecasting tools.
Industry experience in manufacturing, distribution, or CPG.

Responsibilities

Own and lead all demand-side S&OP communication with sales: run the monthly demand review, publish the consensus forecast, and explain forecast changes and risks to sales and executive leadership.
Build and maintain the statistical baseline forecast at the appropriate level (SKU/customer/region), applying time-series and other quantitative methods, and layer in sales/marketing input to produce a consensus demand plan.
Own forecast accuracy and bias measurement (e.g., MAPE, bias) and drive root-cause analysis and corrective action when performance slips.
Set and maintain safety stock and other demand-side planning parameters that protect service levels without over-investing in inventory.
Own demand sensing for new product introductions, promotions, and other demand shaping events.
Ensure all demand data in the planning system (forecasts, overrides, safety stock, master data) is accurate and current.
Partner with the Senior Supply Planner and operations leadership to ensure the demand plan is realistic, communicated in time, and reconciled against supply constraints.
Present the demand plan and key assumptions each month as part of the executive S&OP cycle.
