• Support end-to-end data migration activities (extract, transform, load) for People data and employee master information.
• Carry out sample-based and full-population reconciliations, maintain audit trails, and produce defect logs with supporting evidence.
• Provide insightful analytics to help leaders understand workforce trends, change readiness, and data-related risks.
• Design and execute test scripts related to data validation, system integrations, and reporting outputs.
• Apply root-cause analysis to data issues and recommend sustainable fixes.
• Work closely with stakeholders and delivery partners to align data requirements with future processes and system controls.
• Contribute to documentation including data definitions, mappings, data quality standards, reporting catalogues, and governance logs.
• Support cutover activities including final data checks, readiness testing, KPI reporting, and issue resolution.
• Provide post-go-live insights on data accuracy, adoption, and continuous improvement opportunities.

• Proficiency in Power BI or similar tools, including dashboard development and data modelling.
• Advanced Excel capabilities and strong understanding of data structures, joins, validation techniques, and cleansing methods.
• Experience with User Acceptance Testing (UAT), test execution, or system validation.
• Understanding of end-to-end HR processes and core People data concepts; knowledge of SAP SuccessFactors is an advantage.
