1. Payment Application Impact Analysis & Design
 Own the technical impact analysis and design for all payment applications impacted by
OBP and Core Banking upgrades.
 Prepare and maintain HLDs and LLDs for impacted payment systems, integrations, and
countryspecific payment rails.
 Translate upgradedriven changes into clear technical designs, impact notes, and
implementation guidance.
2. CrossApplication & Stakeholder Coordination
 Work closely with all payment application owners, program leads, and architecture teams
to:
o Understand upgradedriven changes
o Assess functional and technical impact across payment applications
o Estimate the quantum of change across systems and integrations
 Act as the single technical coordination point for payment application changes across
programs.
3. CountrySpecific Payment Rail Impact Handling
 Analyze and design changes across countryspecific payment rails and clearing systems
(e.g., UAEFTS, WPS, ICCS, KNPS, QATCH, RTGS, ACH) resulting from OBP and Core Banking
upgrades.
 Ensure impacted payment applications comply with local scheme rules, message formats,
settlement logic, and regulatory requirements.
 Support schemerelated certification and readiness activities for impacted systems.
4. Integration & Downstream System Alignment
 Design and review changes across integrations between:
o Payment applications

o OBP and Core Banking
o Channels and digital platforms
o Gateways and reconciliation systems (Payment Tracker, Sherlock, Bravos, TLM)
 Ensure all impacted integrations remain aligned with enterprise architecture, security,performance, and resilience standards.
5. Design Support During Build, Testing & Release
 Support build teams by clarifying design changes and resolving impactrelated gaps.
 Assist SIT/UAT by:
o Analyzing defects related to upgradedriven impacts
o Identifying root causes across payment applications and interfaces
 Validate readiness of impacted payment applications for release and production deployment.
6. Technical Governance & Consistency
 Ensure design consistency and traceability across all payment applications impacted by the upgrade.
 Highlight risks, dependencies, and crossapplication impacts to program and senior stakeholders.
 Ensure alignment with change management, release governance, and BCP/DR requirements.
