About the Opportunity

Our client, a leading banking institution, is undertaking a major transformation programme to replace its existing payment engine and core banking systems

The programme requires experienced Senior Process Engineers to document existing business and technical processes, define future-state processes for the replacement platforms, and translate complex banking operations into detailed, build-ready specifications.

The successful candidates will bridge the gap between business stakeholders, technology teams, architects, developers and testers. They must ensure that process documentation accurately captures business rules, system behaviour, data flows, accounting entries, decision logic and exception scenarios.

All deliverables must be sufficiently detailed for business owners to validate and sign off, while enabling technology teams to build and test the replacement systems against approved requirements.

Workstream A: Payments

This workstream focuses on documenting and redesigning end-to-end payment and collection processes across the business.

Key Areas of Responsibility

• Payment orders and payment initiation.
• Instant and real-time payments.
• Collections and payment collection processes.
• Biller and tax payment processing.
• Interbank payments and settlement.
• Payment channels and originating systems.
• Payment processing rules, routing, validation and exception handling.
• Payment message structures, integrations and data transformations.
• ISO 20022 message mapping, including identification of data truncation, loss or incompatibility.
• Reconciliation, payment status management and operational controls.

Candidates should understand South African payment processes and the technical and business implications of migrating payment functionality from legacy platforms to modern payment systems.

Workstream B: Core Banking & Account Management

This workstream focuses on core banking processes, account management, accounting functionality and the associated client, account and mandate data.

Key Areas of Responsibility

• Client onboarding and client master data processes where relevant to the transformation.
• Account opening, maintenance, servicing and lifecycle management.
• Account structures, account relationships and mandate management.
• Banking transaction processing and accounting events.
• Debit and credit postings, general ledger mappings and accounting rules.
• Suspense and control accounts.
• Reconciliation processes and financial control points.
• Client, account and mandate data mapping to target data models.
• System interfaces, dependencies, validations and exception handling.
• Migration from existing mainframe-based functionality to the target core banking environment.

Candidates must be able to connect business events and account activity to the underlying system behaviour, data requirements and financial accounting outcomes.

Key Responsibilities Across Both Workstreams

• Document existing ("as-is") and future ("to-be") business and technical processes.
• Develop detailed end-to-end process models using BPMN 2.0.
• Translate business requirements into implementation-ready process specifications.
• Define process inputs, outputs, business rules, decision points, system interactions and exception paths.
• Develop and maintain business rule catalogues and DMN decision tables where appropriate.
• Map data flows, system interfaces, field-level transformations and dependencies.
• Identify inefficiencies, bottlenecks, redundant activities, control gaps and non-value-adding processes.
• Apply Lean Six Sigma and continuous improvement methodologies to simplify and optimise processes.
• Facilitate workshops with business, technology, operations, architecture, risk, compliance and testing stakeholders.
• Maintain requirements traceability from source requirements through process models, rules and acceptance tests.
• Develop testable acceptance criteria, including test inputs and expected outcomes.
• Maintain a simplification log to identify legacy behaviour that should be changed or excluded from the new systems.
• Document unresolved questions, assumptions and dependencies, assigning them to the appropriate business or technical owner.
• Obtain formal business validation and sign-off for process documentation.
• Ensure process documentation is accurate, complete, consistent, traceable and usable by developers and testers.
