You will be responsible for the customer relationship and collaborative promotional planning for two national big box grocery chains. You will be expected to plan with customer supply chain and internal stakeholders (sales, production, brand teams…). The sales team has a history of positive bias and not much concern for sku mix. The factories are tasked with making to forecast but frequently second guess the inputs given the historical bias and also have issues to produce frequently.
