As the Bank Claims & Fraud Specialist, you will oversee the end-to-end handling of payment disputes and fraud-related activity across Shopify Payments, Klarna, PayPal, and Afterpay/Clearpay.

• Investigate high-risk orders, reseller activity, return fraud, and unauthorized transaction claims.
• Maintain accurate documentation, internal notes, and tracking across Shopify and internal systems.
• Escalate complex or high-risk cases to relevant internal teams when required.
• Support improvements to fraud prevention processes, automation, and operational controls.
• Partner with Web/Tech, Logistics, and third-party platform providers to improve fraud detection and prevention measures within the business.
• Produce regular reporting on fraud trends, chargeback performance, and financial impact.
• Support the wider Customer Experience team with guidance on claims handling, fraud processes, and preventative actions.
• Ensure all work is handled in line with company processes, SLAs, and compliance standards.

You'll need to have:

• Previous experience in fraud management, chargebacks, disputes, risk, or payment operations within e-commerce or retail.
• Strong understanding of Shopify, Klarna, PayPal, and chargeback/dispute processes.
• Excellent attention to detail and organisational skills.
• Strong analytical and problem-solving abilities.
• Ability to manage deadlines and prioritise workload effectively in a fast-paced environment.
