Our mission is to provide reliable, compliant and secure card payment processing that is cost effective for the following transaction types: Card Not Present (CNP): Ecommerce Transactions Card Present(CP): Instore Transactions 🕵🏿 Role Overview As a Senior Specialist — Card Compliance, you will own the loop between acquirer and implementation review, completing transaction-level verification and UAT testing, and manage acquirer sign-off. You will work shoulder-to-shoulder with the pod, freeing developers from compliance investigation and manual UAT so they can focus on building. You will run certification-style testing, validate ISO 8583 behaviour in real environments, and be the pod’s primary interface with acquirers on implementation correctness.

Acquirer integrations responsibility Review acquirer requirement documents and implementation spikes, create actionable verification criteria and provide implementation feedback. Run hands-on UAT: construct and execute test transactions, validate Acquirer responses and outcomes. Verify end-to-end behaviour across Card-Present (CP) and Card-Not-Present (CNP) flows independently of developers to ensure edge cases are caught. Coordinate UAT sessions with acquirers and pod, ensuring sign-off is achieved efficiently. ISO-8583 Message Validation Strong experience validating ISO-8583-based message flows in test and certification environments. Field-level validation, bitmap handling, mapping correctness between internal models and acquirer. Interpret data elements in context and analyse impact on approval/decline behaviour. Negative and edge-case testing; use logs and traces to correlate issues across systems.
