Senior Staff Engineer, Data Migration Lead

Job Description

REQUIREMENTS:

• Total experience 8+ years.
• 8+ years of experience delivering large-scale data migration initiatives (preferably core banking / deposits), including mapping, reconciliation, and cutover support.
• Proven experience leading a data migration workstream and managing vendor delivery teams and cross-functional stakeholders.
• Experience with legacy-to-modern platform migrations (AS/400 to modern core banking, cloud-native or microservices architectures) is strongly preferred.
• Hands-on experience with DMS platforms or other core banking platforms like Flexcube, Temenos etc.
• Data quality and validation concepts
• Working understanding of ETL concepts and migration lifecycle
• Understanding of banking data objects (customer/account, balances, product parameters, transaction history) and downstream impacts.
• Strong analytical skills; comfortable working with large datasets and spotting patterns/variances.
• Proficiency in SQL (preferred) and Excel; experience with data tools (e.g., Power BI) is a plus
• Strong documentation discipline (logs, trackers, evidence packs) and attention to detail.
• Good communication skills to coordinate clarifications and follow-ups across IT, vendor, and business SMEs.
• Structured problem-solving and ability to summarize issues and impacts clearly.

RESPONSIBILITIES:

• Define the overall migration strategy, scope, approach (phasing/co-existence if applicable), and acceptance criteria; align with program releases and cutover milestones.
• Develop and maintain the data migration plan (timeline, environments, mock runs/dress rehearsals, final cutover), including dependencies with Integration, Testing, Operations, and legacy platform teams.
• Govern vendor delivery: review and validate vendor migration design, runbooks, ETL approach, mapping specifications, transformation rules, and reconciliation logic; ensure clear RACI and delivery ownership.
• Coordinate with banks business and IT SMEs to validate source-to-target mappings, reference data alignment, and critical business rules (e.g., product parameters, balances, interest, fees, account status).
• Define and execute banks verification controls with the vendor (record counts, control totals, balance/GL tie-outs, exception management) and obtain stakeholder sign-off for each migration cycle.
• Lead migration defect triage from a banks perspective: ensure issues are logged, prioritized, tracked to closure, and that RCA is completed for recurring defects; escalate risks early.
• Ensure test data readiness for SIT/UAT and parallel run activities (data refreshes, data masking where required, refresh cadence, and data-related test support).
• Plan and coordinate cutover data activities and readiness checkpoints (pre-cutover snapshots, load sequencing, reconciliation checkpoints, rollback/fallback approach) with minimal downtime and operational impact.
• Ensure compliance with banks data governance, security, and regulatory requirements throughout migration (access control, secure transfer, audit trail, retention and masking for non-production).
• Provide regular status reporting (progress, risks, issues, decisions) to program governance and senior stakeholders; maintain RAID and action logs for the data migration workstream.
