Decathlon Switzerland is growing fast (+50 stores, ~500M€ GMV end of 2026). 

To support this growth and the transformation of our finance and procurement ERP, we are seeking a dynamic professional to join our team as an Senior Accounts Payable & AP Leader, based in our Geneva or Lausanne offices.

  • Supplier Relations & Communication: Maintain strong supplier relationships through clear, smooth, and professional communication.
  • Process Harmonization & Performance Recovery: Structure, document, and deploy a standardized Procurement process while diagnosing operational issues and leading targeted recovery plans to boost reliability across the value chain.

3. Process Transformation & ERP Migration

  • Transformation Leader: Act as a key project stakeholder in the migration and transformation of our ERP and Purchase-to-Pay (P2P) systems.
  • Change Management: Lead change management initiatives for the finance team and provide operational guidelines/training to internal non-finance stakeholders.
