This role sits at the operational center of SumUp's card transaction processing engine in Brazil, serving as the bridge between external payment processors and scheme partners and internal teams that depend on accurate, timely data.
You will monitor core payment KPIs including approval and acceptance rates, flagging issues that could impact financial results before they escalate.
