Sr Materials Planner (Master Planner)

Veolia Environnement SA•New Philadelphia, OH

18h•Onsite

About The Position

As the Master Planner, you will orchestrate the translation of unconstrained demand forecasts into highly feasible, operationally validated physical constrained supply plans. You will strictly own the supply plan and material constraints while co-owning critical S&OP tradeoff decisions on 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.

Requirements

Bachelor’s degree in Business Management, Engineering, Supply Chain, or related major (or High School diploma with at least 08 years of planning or related supply chain work experience)
At least 05 years or more of planning or relevant supply chain work experience
05 years of experience on SAP - MRP or Logistic modules
Advanced analytical and technical problem-solving skills to manage complex tradeoff decisions involving scheduling conflicts, capacity disruptions, and material shortages
Experience in ERP systems and advanced MRP planning modules (e.g., SAP/MRP)
Demonstrated proactive leadership and the ability to influence cross-functional internal and external stakeholders through strong negotiation and communication skills
Comfortable analyzing, interpreting, and manipulating large datasets to develop supply scenarios
Strong adherence to drive a Safety First mindset

ASCM CPIM - Certified in production and inventory planning

Responsibilities

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.
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.
Reconcile demand against supply to prepare decision-ready scenarios (Unconstrained x 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.
Drive decision readiness and closure by summarizing key gaps, tradeoffs, 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.
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 v. demand.
Monitor material shortages, coordinate expedite actions with Procurement, and oversee daily Purchase Requisitions (PR) to Purchase Orders (PO) 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 in the area and expand the use of new tools, measurements, and methodologies.
Replicate knowledge related to the Master Planning area to other employees (Coaching/Mentoring).
