The Role
We're looking for an experienced Data Engineer to support a major MOD data transformation programme, focused on assessing and migrating an existing Informatica Data Catalogue into a new catalogue environment.
This is a hands-on role where you'll evaluate what metadata, governance assets, and technical components can be migrated directly, what requires transformation, and what needs to be rebuilt. Your work will help shape the migration approach and reduce delivery risk across the programme.
Key Responsibilities
- Assess the existing Informatica data catalogue and connected data sources
- Analyse metadata quality, completeness, and migration feasibility
- Define metadata mapping, transformation, and remediation requirements
- Produce migration assessments, risks, dependencies, and recommendations
- Prioritise catalogue and ingestion backlogs
- Build and support ETL/ELT pipelines where required
- Transform and structure data for catalogue onboarding
- Work closely with Data Architects and Business Analysts
- Produce technical documentation and support programme delivery
