Role Overview

EY is seeking experienced professionals to support Card Management System transformation, card migration, and payment-system implementation and integration programmes for banks and financial institutions. The role will serve as a functional subject-matter expert across card issuing, payment switching, payment fraud controls, settlement, reconciliation, clearing and delivery from requirements through go-live and stabilisation.

Primary focus: Card Management System implementation and migration; settlement and reconciliation solution design; and integration with card schemes, domestic switching networks, SNAP, BI-FAST and other payment infrastructures.

Main Responsibilities, one of the following:

1. Card Management System and migration

• Lead functional analysis, configuration and delivery for CMS/CMP implementation, enhancement and migration.
• Design end-to-end card issuing lifecycle requirements: onboarding, product set-up, issuance, personalisation, PIN, activation, limits, renewal, replacement, blocking/hotlisting, closure and servicing.
• Perform legacy-to-target gap analysis, data mapping and validation; define mock migrations, cutover sequencing, reconciliation controls, rollback criteria, production validation and stabilisation.
• Analyse authorisation, clearing, settlement, reversals, adjustments, disputes and chargebacks across debit and credit card products.

2. Payment systems and integration

• Lead functional design and integration across international card schemes (Visa/Mastercard), domestic switching networks (Rintis/Alto/Jalin/Artajasa), and payment infrastructures including SNAP, BI-FAST and RTGS.
• Analyse and validate ISO 8583 and ISO 20022 message flows, routing rules, interfaces, APIs and exception handling; familiarity with SWIFT MT/MX is preferred.
• Support scheme/network certification, interface testing, end-to-end testing and production readiness with client, vendor and network stakeholders.

3. Settlement, reconciliation and fraud controls

• Design the target settlement and reconciliation solution, including source-to-ledger data flows, matching logic, settlement cycles, fee and interchange treatment, suspense handling, exception workflows, control points, reporting and audit trails.
• Configure and validate reconciliation, clearing and settlement rules; investigate transaction exceptions, reconciliation breaks, settlement discrepancies and production incidents.
• Define and validate Fraud Detection / Fraud Management integration, including real-time monitoring, rules and thresholds, alerts, case workflows, investigation and reporting.
• Perform root cause analysis and recommend remediation across process, configuration, interfaces, data and operational controls.

4. SIT, UAT, migration and delivery governance

• Define the SIT strategy and scope, integration scenarios, test data, traceability, entry/exit criteria, defect severity and completion evidence across CMS, switching, fraud, settlement and reconciliation interfaces.
• Define the UAT strategy and scope, business scenarios, acceptance criteria, user roles, test data, defect triage, sign-off requirements and operational-readiness evidence.
• Define the migration strategy and scope, including data objects, mapping and cleansing rules, reconciliation controls, mock migrations, cutover sequence, rollback criteria, acceptance and post-migration validation.
• Gather requirements and prepare functional specifications, process flows, configuration documents, user stories, test artefacts, issue logs, operating procedures and training materials.
• Coordinate business, operations, technology, vendors and payment networks; manage status, risks, issues, decisions and knowledge transfer. Manager candidates will lead workstreams and coach team members.

Required Qualifications and Experience

• Bachelor's Degree or higher in IT, Computer Science, Engineering, Information Systems, Finance or a related discipline.
• 5–12 years of relevant experience in banking, cards, payments, transaction banking, fintech, payment processing or financial-services technology.
• Hands-on experience with CMS/CMP, debit/credit card issuing, card migration and payment-system integration.
• Strong knowledge of the card issuing and transaction lifecycles, including authorisation, clearing, settlement, reconciliation, reversals, adjustments, disputes and chargebacks.
• Experience with Visa/Mastercard and Rintis/Alto/Jalin/Artajasa, with familiarity in SNAP and BI-FAST.
• Hands-on experience in a PCI-DSS-compliant system or cardholder-data environment.
• Experience with Fraud Detection / Fraud Management systems, including transaction monitoring, rules, alerts, cases and investigation workflows.
• Working knowledge of ISO 8583 and ISO 20022; familiarity with SWIFT and RTGS.
• Strong business analysis, structured problem-solving, stakeholder management, communication and documentation skills.

Preferred experience

• Prior experience in one or more delivery roles: Project Manager, Solution Architect, Business Analyst, or Quality Assurance / Test Lead.
• Card scheme or payment-network certification; issuer, acquirer, switch, payment hub, settlement or reconciliation-engine implementation.
• Experience with recognised card platforms such as HPS PowerCARD, OpenWay Way4, VisionPLUS, PRIME, TSYS, FIS, Fiserv, Compass Plus or comparable solutions.
• Experience leading workshops and workstreams in complex, multi-vendor delivery environments.
