About the Role

• Process Improvement & Standardization: Lead end-to-end cross-country Finance transformation initiatives within billing and controlling, from opportunity identification through scoping, stakeholder alignment, delivery, and adoption, applying Lean and continuous-improvement principles to standardize processes before automating them, while systematically identifying and implementing AI, automation, and process redesign opportunities to eliminate manual work, strengthen controls, and embed scalable best practices across the pan-European structure.
