As part of the wider Credit Cards initiative, you will lead a dedicated engineering team and work closely with our Finance, Fintech, Fraud and other teams to ensure every aspect of the new product is robust, scalable, and seamlessly integrated with existing iwoca systems. The role will provide:

Ownership and influence:

• Define and manage the product roadmap for our card payment processing and authorisation flow and their interactions with the card ledger.

• Own the end-to-end credit card transaction flows, including authorisation, clearing, settlement, chargebacks, and cashback, taking into account different transaction types and relevant edge cases.

• Work with our engineering and finance teams to help shape the technical product direction for our in-house ledger, evolving our existing blueprint and growing into a subject matter expert over time.

• Influence the system architecture decisions, aligning product logic with scheme and regulatory constraints.

Technical expertise and collaboration

• Translate business rules and scheme requirements into clear technical specifications for authorisation and processing systems.

• Maintain up-to-date system documentation, process diagrams, and test case mappings to support quality assurance and compliance.

• Identify and document Visa and Mastercard requirements relevant to launch, ensuring their incorporation into system flows and data requirements.

Product development and growth

• Use your card payments knowledge to map transaction flows, turn rules into clear specifications, and work closely with product, engineering, finance and risk teams.

• Continuously develop your technical and domain expertise, mastering card payments, scheme requirements, and regulatory frameworks.

• Take a product from concept to market and iterate based on feedback and test data to make it a success.

Essential:

• Experience working on card payments, issuing, and processing systems, including tokenisation and scheme integration

• Practical knowledge of payment protocols and standards such as EMV, PCI, and Visa/Mastercard scheme requirements

• Ability to map detailed transaction flows, define precise system behaviours and write clear, detailed functional requirements

• Experience with RESTful services, monitoring and alerting tools, and working knowledge of browser-based testing and debugging.

• A collaborative approach to working with cross-functional teams and communicating technical requirements clearly

Bonus:

• Familiarity with the full card lifecycle, including onboarding, fraud, and dispute handling.

• Experience with ISO 20022 and PSD3 regulatory frameworks.

• Comfortable working in an early-stage product environment with evolving requirements.

We expect to pay from £80,000 - £120,000 for this role. But, we’re open-minded, so definitely include your salary goals with your application. We routinely benchmark salaries against market rates, and run quarterly salary and performance reviews.
