I’m currently recruiting for Data Migration Engineer to join a major global transformation programme for a large multi-site UK organisation.

The programme is replacing the organisation’s core ERP and middle-office platforms, with data migration being a critical part of the transformation. We’re looking for experienced analysts who can take ownership of the hands-on data preparation, mapping, cleansing and validation activities required ahead of the migration and upcoming go-live.

Key Responsibilities

You will be involved in:

• Mapping source data against target data models and applying agreed mapping rules

• Cleansing and preparing data to a load-ready standard

• Identifying and resolving data-quality issues and exceptions

• Supporting data validation and reviewing migration outputs with relevant SMEs

• Documenting mapping rules, transformations and data decisions

• Working across multiple data domains and applications

• Liaising with data owners, application owners and operational SMEs to resolve queries

• Following a structured data migration methodology and working to agreed delivery timelines

• Supporting the final handover of migration activity and documentation

Essential Experience

• Proven hands-on Data Migration / Data Preparation experience
• Strong experience in Data Mapping, Data Cleansing and Data Validation
• Strong Excel skills
• SQL and/or Python
• Power Query
• experience working with structured datasets and data migration processes
• Strong stakeholder communication skills
• Ability to work independently and pick up established processes quickly

Desirable Experience

Experience with any of the following would be highly beneficial:

• SAP / SAP S/4HANA

• ERP implementation or transformation programmes

• Master Data Management

• Data-quality tools

• Large-scale or multi-site organisations

• Experience working across multiple applications or data domains

This is not a general Business Analyst role and it isn't purely a data validation/SME position. The focus is on hands-on data migration preparation, taking source data through mapping, cleansing and preparation so it is ready for migration.
