About the job
The Demand Planner is a key driver in generating and managing accurate customer demand signals in Sanofi planning tools (Kinaxis). This position ensures the alignment of Business Units (BUs) and markets with Manufacturing and Supply (M&S) through collaboration with stakeholders at the market such as Commercial BUs, Regulatory, Finance and local Supply Chain (Demand Managers, Logistics and Customer Fulfillment/Engagement).
This is achieved by translating local conditions such as product life cycles, sales patterns and what-if scenarios in actionable data in our planning tools. Another element of the role is on continuous improvement through performance analysis and actions to help achieve the goals of the organization to supply products in a reliable and competitive way.
We are an innovative global healthcare company with one purpose: to chase the miracles of science to improve people’s lives. We’re also a company where you can flourish and grow your career, with countless opportunities to explore, make connections with people, and stretch the limits of what you thought was possible.
