Data Migration Engineer

The Data Migration Engineer is responsible for planning and executing the end-to-end transformation and migration of large, complex datasets across differing source and target platforms. This role carries direct responsibility for data extraction, validation, and reconciliation within high-scrutiny, government-linked environments - safeguarding data integrity, traceability, and audit compliance throughout every phase of the migration lifecycle.

What You'll Do

1. Migration Stratefgy & Goverance

• Plan and strategize the end-to-end data transformation and migration approach for large, complex datasets across differing source and target platforms.
• Establish and enforce data migration standards, governance, and documentation across project implementations.

2. Data Extraction, Validation & Reconciliation

• Lead the extraction, validation, and reconciliation of production data, working directly within high-scrutiny, government-linked environments.
• Troubleshoot and resolve complex data discrepancies arising during migration and validation.

3. Cutover & Execution

• Coordinate mock runs, trial loads, and final cutover execution, ensuring data integrity is maintained throughout.

4. Compliance, Traceability & Performance

• Ensure strict data traceability and compliance with audit requirements throughout the migration lifecycle.
• Monitor and optimize database performance and availability during and after migration, ensuring service levels are met and implementing improvements when needed.

5. Stakeholder & Technical Engagement

• Engage stakeholders and application teams, explaining technical decisions and reviewing data models to ensure migration approach aligns with system design.

Who You Are

Must-Have

• Proven track record of delivering data migration projects in a public sector or other high-scrutiny, government-linked context.
• Strong hands-on proficiency with Python and ETL tooling.
• Hands-on experience with native cloud migration services such as AWS Database Migration Service (DMS) and Azure Migration Services.
• Demonstrated ability to lead mock runs, trial loads, and cutover execution while maintaining strict data integrity.
• Strong troubleshooting skills for resolving complex data discrepancies during migration and validation.
• Must be a Singapore Citizen or Permanent Resident, as this role requires direct access to sensitive production data.

Good-to-Have

• Experience working with database performance tuning and monitoring tools.
• Familiarity with data governance, audit, and compliance frameworks in regulated or public sector environments.
• Relevant cloud or data certifications (e.g. AWS Certified Database - Specialty, Microsoft Certified: Azure Database Administrator Associate).
• Experience engaging directly with stakeholders and application teams on technical data model decisions.

This role is not a fit if:

• You are not eligible to work with sensitive production data as a Singapore Citizen or Permanent Resident.
• You prefer low-scrutiny environments over rigorous audit, traceability, and compliance requirements.
• You're uncomfortable troubleshooting complex, high-pressure data discrepancies during live cutover windows.
• You see documentation and governance standards as optional rather than core to the job.
