• Provide clear documentation of migration processes, data mappings, data quality checks, and testing results.
• Support user acceptance testing (UAT) and resolve data‑related issues promptly.
• Ensure migrations comply with data governance, security, and regulatory requirements.
• Work with case management software and related systems to understand data structures and workflows.

• Proven experience in public sector large‑scale data migration projects.
• Strong SQL development skills within MySQL environments.

• UK NPPV3 Security Clearance with at least 12 months remaining.
• Ability to work effectively as part of a data team and with cross‑functional stakeholders.

• Experience with Oracle databases (alongside MySQL).
• Knowledge of data modelling, data warehousing, or data integration tools.
• Experience in working with agile project delivery methodologies.
• Ideally Azure and experience in Azure Data Factory for ETL.
