Job description

Marmon Foodservice Technologies, Inc. As a part of the global industrial organization Marmon Holdings—which is backed by Berkshire Hathaway—you’ll be doing things that matter, leading at every level, and winning a better way. We’re committed to making a positive impact on the world, providing you with diverse learning and working opportunities, and fostering a culture where everyone’s empowered to be their best.

Though you may not know us by name, you’ve most likely enjoyed meals and refreshments supported by our industry-leading brand portfolio. For decades, we’ve designed and manufactured foodservice equipment for some of the world’s biggest, most recognized consumer brands.

We are driven to innovate with a clear purpose in mind: revolutionizing the future of foodservice. Guided by our commitment to Doing Things That Matter, Leading at Every Level, and Winning a Better Way, we focus on delivering meaningful impact for our customers, our communities, and each other.

The SIOP Manager is responsible for building a world‑class, data‑driven Sales, Inventory & Operations Planning (SIOP) process by integrating direct demand signals from key customers and strategic distributors into the ERP planning system. Reporting to the Supply Chain leadership, this role serves as the business owner for the SIOP process and the Infor LN SIOP module implementation.

Unlike a traditional demand planner focused on forecasting internally, this role will establish collaborative planning with customers, measure forecast accuracy and create a closed‑loop continuous improvement process that increases visibility, inventory productivity, and service levels.

The objective is to transform planning from internally generated forecasts into a collaborative, technology‑enabled process supported by ERP automation and real‑time demand intelligence.

Key Responsibilities

• Lead the implementation and continuous improvement of the Infor LN SIOP module.

• Establish direct demand planning collaboration with key customers and top distributors.

• Create a formal closed-loop process that measures forecast accuracy by customer and distributor and provides regular feedback to improve future planning.
• Develop dashboards and KPIs to monitor forecast accuracy, bias, inventory impact, and service performance.
• Partner with IT and ERP teams to implement enhancements, automation, and system improvements.
• Standardize planning assumptions, master data governance, and planning parameters.
• Identify gaps between customer forecasts and actual demand and drive corrective actions.
• Facilitate monthly SIOP meetings, including but not limited to Executive SIOP meeting, by presenting demand trends, risks, and recommended actions.
• Support inventory optimisation by improving forecast quality and planning discipline.
• Work cross‑functionally with Sales, Operations, Purchasing, Finance, and IT to improve planning capabilities.
• Lead continuous improvement initiatives that simplify processes and reduce manual work.
