Senior Payments Specialist - Card Compliance [Card Rails]

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.

• Own ongoing alignment with acquirer specifications, scheme mandates, and regulatory requirements relevant to Card Rails implementations.
• Maintain awareness of scheme rule changes (e.g. Visa, Mastercard) and assess impact and changes required on the Card Gateway.
• Manage UAT testing and sign-off of scheme compliance items with Acquiring partners and pod.
• 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.
• Strong experience validating ISO-8583-based message flows in test and certification environments.
• Conduct negative and edge-case testing; use logs and traces to correlate issues across systems.

• Proactive Ownership: Take initiative to find problems to solve, own projects end-to-end, and identify and propose solutions for quality gaps.
• Cross-Functional Collaboration: Work effectively in fully remote teams, with strong written and verbal English communication skills.
• Technical Articulation: Ability to clearly articulate complex technical and quality concepts to diverse audiences.
