<div>
<p id="message">The <strong>AI AML Engineering squad</strong> sits at the heart of SumUp's<strong> Risk &amp; Compliance</strong> tribe, building the data products and engineering solutions that protect millions of small businesses from financial crime. We're in the middle of something genuinely new: <strong>Risk Decision Center (RDC)</strong>, also known as SumUp Sentinel, is our flagship product designed to automate up to 90% of fraud and AML case investigations — and it can only work if the data underneath it is correct, complete, and trusted. This role exists because we can't build reliable automation on shaky foundations, and we need an engineer who cares deeply about getting that right.</p>
