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

1. Proven hands-on Data Migration / Data Preparation experience
2. Strong experience in Data Mapping, Data Cleansing and Data Validation
3. Strong Excel skills
4. SQL and/or Python
5. Power Query
6. experience working with structured datasets and data migration processes
7. Strong stakeholder communication skills
8. 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.
