Sr Materials Planner Master Planner

Job Description

As the Master Planner, you will orchestrate the translation of unconstrained demand forecasts into a highly feasible, operationally validated physical constrained supply plan. You will strictly own the supply plan and material constraints while co‑owning critical S&OP trade‑off decisions on a monthly cadence of the S&OP Supply Chain Review (SCR). You will be responsible for validating demand inputs, running capacity and material constraints, reconciling gaps, and driving the execution of the locked operating plan across cross‑functional teams.

• Key Duties & Responsibilities within the S&OP Process (4‑Week Cadence)

• Week 1 – Demand Validation & Data Integrity:
  Lead alignment that ensures demand inputs are clean, realistic, and aligned before SCR begins. Challenge and validate the forecast vs. actuals (bias and error), identify abnormal demand spikes, and review backlogs with Customer Fulfillment Solutions (CFS). Ensure master data integrity by validating lead times, batch/lot sizes, and safety stock levels.
• Week 2 – Supply Review & Material Feasibility:
  Translate demand into a feasible supply plan by evaluating material and capacity constraints. Run the MRP simulations to identify raw material shortages or long‑lead‑time risks, and evaluate production sequences against available vessel and labor capacity to pinpoint bottlenecks together with Production Planner & Scheduler. Simulate scenario planning, including pull‑in/push‑out order strategies and alternate sourcing.
• Week 3 – Pre‑S&OP Balancing:
  Reconcile demand against supply to prepare decision‑ready scenarios (unconstrained vs. constrained). Identify unmet demand, define allocation strategies and service priorities for key customers, and document supply and capacity risks alongside Supply Chain opportunities. Recommend inventory strategies, such as building ahead when capacity allows or deferring production to avoid excess.
• Week 4 – PCR & Execution Kick‑Off:
  Drive decision readiness and closure by summarizing key gaps, trade‑offs, and risks for the Plan Consensus Review (PCR). Upon locking the approved operating plan, communicate execution priorities clearly to Production, Procurement, Logistics, and CFS teams. Propose targets for the next cycle, including service levels and adherence expectations.

Daily Standard Work & Execution

• Responsible for driving the execution of the wing‑to‑wing operational plan while reacting to operational realities, setting priorities and alignment with Supply Chain partners to balance supply vs. demand.
• Monitor material shortages, coordinate expedite actions with Procurement, and oversee daily Purchase Requisition to Purchase Order conversions.
• Track production adherence against the schedule, update for quality holds or unplanned downtime, and adjust short‑term schedules within the planning horizon.
• Manage inventory touchpoints, including validating system accuracy, reviewing service levels, and identifying and driving reductions for slow‑moving/non‑moving (SMNM) or obsolete inventory.
• Lead continuous improvement projects and support New Product Introductions (NPI) and lifecycle management.
• Define methodologies for prioritizing the activities of the Master Planner team based on information from other areas of the company.
• Propose and lead the implementation of new policies, processes, and procedures within Supply Planning to ensure continuous improvement and expand the use of new tools, measurements, and methodologies.
• Replicate knowledge related to the Master Planning area to other employees (coaching/mentoring).

• Team player, proactive self‑starter behavior.
• Develop relationships through strong communication and negotiation skills with internal and external stakeholders.
• Ability to effectively communicate information and data (verbal and written).
• Supports continuous improvement activities.
• Comfortable analyzing and interpreting large datasets or spreadsheets.

• Advanced analytical and technical problem‑solving skills to manage complex trade‑off decisions involving scheduling conflicts, capacity disruptions, and material shortages.
