  • Communicate stock status, supply risks, and mitigation options to all stakeholders during S&OE (Sales and Operations Execution) meetings, highlighting the business impact of oversales and the inventory health risk of undersales.

  • Deliver reporting and analytics by using Power BI tools developed for planning functions and creating reports that support business decisions from a supply planning perspective.

  • Represent Supply in market activities such as short- and mid-term demand changes, portfolio renovations, and promotional action executions.

  • Focus on personal development and continuous improvement by driving enhancements in both processes and reporting/analytics.

What are we looking for?

  • Degree-level education and fluency in English.

  • Strong business understanding with a customer-focused mindset.

  • Advanced MS Excel skills and proficiency in MS Office; experience with SAP and Power BI is a plus.

  • Analytical, digitally savvy, and knowledgeable about end-to-end supply chain processes.

  • Ability to build collaborative relationships and communicate effectively across teams.

What can you expect from Mars?
