• Coordinate delivery activity across ETL migration workstreams, managing risks, dependencies and milestones
• Work with business teams, developers, data teams and external partners to support joined-up delivery
• Prepare and maintain documentation including migration plans, RAID logs, and status updates
• Support data mapping, transformation, reconciliation and validation activities
• Coordinate testing activity, including planning, defect tracking and business validation
• Support implementation, cutover, go-live and post-delivery follow-up
• Identify opportunities to simplify processes, reduce complexity and improve standardisation
• Ensure delivery aligns with governance, security, audit and change control requirements
• Contribute to continuous improvement of ETL delivery practices and documentation

• Experience in a systems, delivery, data integration or ETL-related role within IT
• Strong ability to translate business and technical requirements into structured delivery outputs
• Experience coordinating delivery across multiple teams, stakeholders and suppliers
• Experience supporting ETL, data migration or platform transition activity
• Understanding of testing, reconciliation and validation as part of data delivery
• Strong organisational and planning skills, with the ability to manage multiple priorities
• Clear communication skills, with confidence working across technical and non-technical teams
• Experience producing structured documentation such as plans, reports and tracking logs
• A proactive, detail-focused approach with strong ownership and follow-through

It’s a bonus if you have:

• Experience with ETL tools, data transformation or enterprise data flows
• Experience in retail, wholesale or other complex operational environments
