Sales and Operations Planning Manager

Your Job

Guardian Glass is looking for a Sales and Operations Planning Manager to join our team!

This role can be based out of DeWitt IA, Richburg SC, or Auburn Hills MI.

As a Sales and Operations Planning Manager, you'll sit at the intersection of supply chain, operations, and commercial teams, turning customer demand into executable production plans that drive performance across our North American Glass network.

This is a highly visible, newly created role where your ability to influence, analyze, and lead through collaboration will have a direct impact on service, inventory health, and operational success. If you thrive in dynamic environments, enjoy solving complex planning problems, and want to make a tangible impact, this is an opportunity to grow your career with a global manufacturing leader.

You’ll join Guardian’s North America Glass organization, working closely with plant leadership, commercial partners, customer service, and supply planning teams. Reporting to the Regional Master Planning Manager, you’ll serve as the critical link between supply chain strategy and plant execution, helping ensure our operations are aligned to customer needs and business goals. Our teams value initiative, thoughtful problem solving, and leadership through influence rather than authority.

• Translate integrated business planning outputs from Rapid Response into actionable production schedules within the M3 ERP system

• Develop and maintain supply planning assumptions based on input from plant operations
• Create and manage inventory stocking strategies aligned with demand patterns, commercial strategy, and customer contracts
• Optimize inventory levels while managing aging inventory to reduce risk of obsolescence
• Collaborate with warehouse and shipping leaders to align inventory levels with capacity and dock availability
• Provide input into inventory strategies for new products, existing items, and product phase outs
• Travel up to 20% to support plants within your area of responsibility

• Experience in production planning, supply planning, and/or finite scheduling
• Strong analytical and organizational skills with experience turning data into actionable insights
• Experienced and comfortable working with large data sets within Microsoft Excel
