Data analyst

Help shape the success of a complex data migration by investigating data quality, preparing source data and validating that what moves is complete and faithful. Working across multiple organisations, you'll turn unfamiliar datasets into clear, evidence-based findings that guide migration decisions.

• Investigate unfamiliar datasets to understand their structure, content, relationships and variation across organisations.
• Identify and explain data quality issues, trace them to source records, mappings or transformations, and quantify their impact on migration.
• Design repeatable comparisons and reconciliation checks to validate that migrated data is complete, consistent and faithful.
• Write reusable SQL and Python scripts for profiling, exception detection and validation, using Azure Databricks, Git and dbt where relevant.
• Communicate findings clearly to technical and non-technical audiences, using Excel and Power BI or Tableau to present evidence and track issues.
