Job Description:

Fraud Prevention Manager

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.
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.
What You'll Do
* Lead 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
* Own the global Acquiring fraud strategy roadmap, translating fraud trends, performance data, and market needs into effective rule optimisation, threshold management, and authentication strategies
* Drive 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
* Partner cross-functionally with Operations, Engineering, Data Science, Product, and regional leaders to prioritise model development, improve fraud tooling, and deliver measurable outcomes
* Monitor fraud and chargeback performance through KPIs and data analysis, identifying risks, diagnosing root causes, and protecting approval rates across all markets
You'll Be Great for This Role If
* 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.
* You're an experienced people leader who can hire, set goals, coach, and manage performance with clarity and care.
* 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.
* You can influence and align cross-functional teams across Operations, Engineering, Data Science, Product, and senior business stakeholders, and you communicate fluently in English.
* You hold a degree in Engineering, Statistics, Mathematics, Physics, or a related quantitative field.
* You adapt quickly, prioritise well under pressure, and bring a growth mindset - staying curious and always looking for better ways to solve problems.
