About SumUp

We believe in the everyday hero — those who have the courage to follow their passion and the determination to realise their dreams.

Small business owners are at the heart of all we do, so we’re creating powerful, easy-to-use financial solutions to help them run their businesses. With a founder’s mentality and a team-first attitude, our diverse teams across Europe, South America and the United States work together to ensure that small business owners can be successful doing what they love.

💡 Team Description

You’ll join our Global Fraud Strategy team, a newly formed function within Risk & Compliance (R&AF) that’s shaping SumUp’s global approach to fraud prevention.
The team builds the systems, data models, and governance frameworks that protect our merchants across multiple products  from onboarding to payments, banking, and cards.

Working from Berlin or Sofia, you’ll collaborate closely with our product, data, and operations teams to design smarter fraud strategies that scale with our growth.

This is a highly analytical, cross-functional, and strategic role, perfect for someone with deep fraud prevention expertise who’s ready to shape the next generation of automated, data-driven defenses across Europe.

⚙️ What You’ll Do

• Define and drive the fraud prevention strategy across SumUp’s EU products (Onboarding, Payments, Cards, Business Account).
• Design and enhance decision rules, scoring models, and control frameworks that prevent fraud, chargebacks, and losses.
• Advise Product, Engineering, and Operations on fraud risks in new launches and features, ensuring compliance with scheme and regulatory standards.
• Lead proofs of concept for new tools, AI-driven fraud detection, and automation solutions.
• Build performance dashboards and reports to track KPIs such as fraud rates, chargeback ratios, and internal declines.
• Collaborate with global and regional stakeholders (Risk, Product, Data Science, Engineering, Operations) to ensure fraud strategies are consistent and scalable.
• Represent SumUp in industry discussions and fraud forums, sharing insights and best practices.

🙌 You’ll Be Great for This Role If

• You have deep expertise in payments, cards, or banking fraud prevention, including scheme rules and compliance.
• You’re highly analytical, with strong SQL and data manipulation skills, and can translate insights into strategy.
• You’ve worked in product-driven environments, influencing design decisions through a risk lens.
• You can manage complex stakeholder networks and guide cross-functional teams with clarity and influence.
• You have experience using rule engines, fraud tooling, and scoring models (e.g. NOTO, Mastercard Connect).
• You think logically and approach fraud as both a data problem and a strategic challenge.
• You’re curious about emerging technologies (AI/ML) and how they can enhance fraud detection.
• Bonus: coding experience (Python) or background in data science, compliance, or risk governance.
