Join group.one as a "Product Controller (m/f/d)." Key Responsibilities In this role, you will make the product organization commercially sharp and evidence-led by creating a single, trusted view of product performance across commercial, customer, and operational dimensions. You will support Product Managers and Commercial Leads by owning controlling, contracts, and purchasing, ensuring decisions are grounded in accurate KPIs and strong market benchmarks—without being the decision owner yourself.
