JobRequisition Number: ISSG-005

JobLevel: 10+ years of relevant experience (L4)

Location:Singapore

Role Purpose:

Data MigrationLead to support a core banking transformation program for a client based in theSingapore. The lead will own the data migration stream in its entirety,including strategy, driving requirement analysis, and To-Be solution design andintegrations. This is a core banking implementation role. The candidate musthave hands-on, end-to-end experience delivering core banking transformationprograms (not advisory-only exposure), and must be comfortable working directlywith product vendors to challenge, validate, and finalize the To-Be systemdesign.

Key Responsibilities:

MULTIVENDOR, MULTI-COUNTRY TEAM

• Analyze datarequirements and design solutions.

• Define theproject-specific data migration strategy, approach, and plan, coveringmigration scope, methods, tooling, the reconciliation framework, and lifecycledeliverables in full alignment with the program's Data Migration and CutoverPolicy.

• Own the workstreamend to end. Analyze data requirements, design the To-Be migration solution, anddrive requirement and design sign-off with business and technologystakeholders.

• Manage all datamigration activities and cross-team dependencies, coordinating the DataMapping, Data Profiling & Cleansing, Reconciliation, and Static/Master Dataworkstreams, each staffed by dedicated specialists whose outputs this roleorchestrates.

• Plan and sequencethe migration lifecycle across its full arc: profiling and cleansing, mappingand build, iterative migration test runs, dress rehearsals, and the productioncutover weekend.

• Drive data mappingbetween legacy source systems (core platform, end-user computing applications,and head-office systems) and the target lending platform, validating mappinglogic and transformation rules with source and target subject-matter experts.

• Support SIT/UAT testplanning and execution, triage integration and data defects, and driveresolution with vendor and delivery teams through to closure.

• Lead migrationvalidation and reconciliation for the core banking modules. Record counts andcontrol totals across every stage, through mock loads, dress rehearsals, andproduction data migration, and agree acceptance criteria for reconciliationvariances with end users.

• Support cutoverplanning and hypercare through go-live, ensuring readiness against theprogram's formal entry/exit criteria at each gate (tool test, dress rehearsal,cutover / go-no-go).

• Prepare regularstatus reporting on migration progress. Identify, resolve, and escalate risksand issues proactively, particularly where cross-team or vendor dependenciesput milestones at risk.

• Manage stakeholdersacross business, technology, and vendor organizations, including presentingmigration approaches, options, and risk positions directly to seniorstakeholders and steering forums.

Key Requirements:

• 10+ years ofhands-on data migration / integration implementation experience within a corebanking transformation program. Candidates with advisory-only or purelyfunctional-consulting backgrounds will not meet the bar for this role.

• Practical,personally delivered experience across the full migration lifecycle: datamapping, profiling, cleansing, reconciliation design, mock/trial loads, dressrehearsals, and production cutover execution.

• Working knowledge ofcore banking data structures for lending products: the facility / limit / loan/ transaction hierarchy, collateral and guarantee linkage, schedules, accruals,and balances. Strongly preferred given this release's lending scope.

• A strong grasp ofreconciliation principles: record counts versus control totals, multi-levelreconciliation (source, transformation, target, and GL), and the discipline ofaudit-ready evidence.

• Excellent writtenand verbal communication skills; comfortable presenting solution options,trade-offs, and status directly to senior stakeholders and vendor leadership.

• Must be based in theSingapore for the entire duration of the project. The exact work location willbe communicated after client confirmation.

Good to Have

• Prior experience acting as techno-functional SME across core banking plus one or more ofPayments, Trade Finance, or Lending domains.

• Direct implementation experience on a modern packaged lending or universal-banking platform, particularly customer, lending, and trade data migration.

• Experience operating within a formal, policy-governed migration structure with defined KPIs, standard deliverable templates, and entry/exit gate criteria, rather than ad hoc migration delivery.

• Exposure to multi-country, multi-release transformation programs, where lessons learned from one market's release are systematically carried into the next.

• Familiarity with data masking and production-data handling controls for non-production test environments.

Technical Skills:

• Migration Lifecycle: Data mapping, data profiling, data cleansing, mock/trial loads, dress rehearsals, production cutover execution

• Reconciliation: Record counts vs control totals, multi-level reconciliation (source, transformation, target, GL), audit-ready evidence

• Core Banking Data: Lending data structures – facility / limit / loan / transaction hierarchy, collateral and guarantee linkage, schedules, accruals, balances

• Source-to-Target: Mapping logic andtransformation rules across legacy core platform, end-user computingapplications, and head-office systems

• Delivery: SIT/UAT support, defect triage, entry/exit gate criteria, cutover and hypercare

• Controls: Data masking and production-data handling for non-production environments
