Description
<h1><strong>Fraud Prevention Manager</strong></h1>
<p><strong>SumUp's Fraud Prevention team sits at the intersection of risk, data, and global payments, and we move fast. We're a team of specialists tackling one of fintech's most dynamic challenges: staying ahead of fraud at scale, across multiple markets and products. As we shift from a market-based to a global, product-focused model, we're looking for a Fraud Prevention Manager to lead our Acquiring domain worldwide, someone who thrives in ambiguity, leads with clarity, and gets things done.</strong></p>
<p>In this role, you'll own the global Acquiring fraud strategy, lead a team of fraud specialists, and work closely with Operations, Engineering, Data Science, and Product to build scalable, high-impact prevention capabilities. You'll report directly to the Head of Risk & Fraud Prevention and partner with a second global fraud prevention manager focused on non-acquiring fraud.</p>
<p><strong>What You'll Do</strong></p>
<ul>
<li><strong>Lead</strong> a team of fraud specialists through clear goal setting, coaching, and strong execution standards, while hiring for open roles and building a culture of ownership and accountability</li>
<li><strong>Own</strong> the global Acquiring fraud strategy roadmap, translating fraud trends, performance data, and market needs into effective rule optimisation, threshold management, and authentication strategies</li>
<li><strong>Drive</strong> the review, testing, and migration of EU Acquiring rules from NOTO to SumUp's internal rule engine, ensuring controls remain effective as fraud patterns evolve</li>
<li><strong>Partner</strong> cross-functionally with Operations, Engineering, Data Science, Product, and regional leaders to prioritise model development, improve fraud tooling, and deliver measurable outcomes</li>
<li><strong>Monitor</strong> fraud and chargeback performance through KPIs and data analysis, identifying risks, diagnosing root causes, and protecting approval rates across all markets</li>
</ul>
<p><strong>You'll Be Great for This Role If</strong></p>
<ul>
<li>You bring proven experience in fraud prevention, fraud strategy, or risk management within payments or fintech, including hands-on work with rules engines, decision systems, or authentication strategies.</li>
<li>You’re an experienced people leader who can hire, set goals, coach, and manage performance with clarity and care.</li>
<li>You’re data-driven and comfortable working with databases, building KPIs, and measuring the impact of strategy changes; SQL or coding skills are nice to have.</li>
<li>You can influence and align cross-functional teams across Operations, Engineering, Data Science, Product, and senior business stakeholders, and you communicate fluently in English.</li>
<li>You hold a degree in Engineering, Statistics, Mathematics, Physics, or a related quantitative field.</li>
<li>You adapt quickly, prioritise well under pressure, and bring a growth mindset — staying curious and always looking for better ways to solve problems.</li>
