• Build and enhance fraud MI dashboards and reporting packs to support internal governance, regulatory reporting, and operational efficiency.
• Work cross-functionally with Risk, Compliance, and Operations to design and implement targeted fraud controls.
• Optimise rule-based and data-driven fraud detection models in line with the latest scheme and regulatory requirements.
• Stay informed on fraud trends across the payments ecosystem and translate insight into strategy and preventative controls.
• Support regulatory, audit, and scheme reporting as required, representing the fraud function in relevant forums.

• Minimum 2+ years’ experience in a fraud role within the payments, acquiring, or card issuing space – ideally at a regulated EMI, PSP, or acquirer.
• Strong working knowledge of card scheme rules (Visa, Mastercard) and risk management expectations.
• Experience managing end-to-end fraud investigations, including the use of tools such as Experian, CIFAS, and fraud detection systems.
• Demonstrated ability to produce meaningful fraud MI and insights to drive decision-making and performance improvement.
• Excellent communication and stakeholder engagement skills, including the ability to challenge and influence constructively.
• Proactive, analytical mindset with the ability to work independently and take ownership of key risk areas.
• Strong Microsoft Office skills; experience with SQL, fraud tools, or analytics platforms is an advantage.

• Individual and company performance bonus.
• Private medical health insurance.
• 25 Days holiday rising to 30 with service + bank holidays.
• A diverse multi-cultural working environment.
• Office gym available at Milton Keynes office only.
