Master Data Specialist in Tottenham

Master Data Specialist (SAP S/4HANA Migration and Data Archiving) - Kings Cross, London (4 days hybrid) | Permanent | £75,000
A global manufacturing business is moving from SAP ECC to S/4HANA and needs an experienced master data specialist to lead two linked pieces of work: getting master data ready for the migration, and cutting down years of legacy data held across its global operations. The aim is to reduce around 5TB of data to 1.5TB.
This is a standalone role. You'll be the business's master data specialist, working directly with data owners across the company, the internal IT team, a US-based systems integrator delivering the migration, and a managed service provider running support alongside it.
This is an urgent hire, so we're looking for someone available to start on one month's notice or less.
What you'll be doing:
S/4HANA migration
Analysing master data to find duplicates, gaps and inconsistencies, then coordinating the clean-up with business owners
Preparing customer, supplier, material and Finance data for conversion, including Business Partner / CVI readiness
Supporting test cycles, conversion rehearsals and UAT: preparing test data, validating results, logging defects and retesting
Reconciling source and converted data to confirm completeness and accuracy
Legacy data reduction and archiving
Identifying data for retention, archiving, historical access or deletion, and documenting findings for business-owner decisions
Supporting company-code rationalisation and wider data reduction work
Validating historical data extracts so retained data stays complete and accessible
Across both
Acting as the main data contact for the systems integrator and managed service provider
Documenting standards, decisions and validation results, and building governance processes that last beyond go-live
Working with teams across Finance, Sales, Procurement, Supply Chain, Manufacturing and Quality
What you'll need:
Hands-on SAP S/4HANA migration experience (essential)
Data archiving and legacy data reduction experience on a large SAP estate (essential)
Practical SAP master data experience across ECC and S/4HANA
A track record of analysing, cleansing, validating and reconciling business data
Strong Excel skills and comfort working with large datasets
The confidence to work independently and chase issues through to resolution with internal teams and external partners
Able to start on one month's notice or less
Useful but not essential:
Familiarity with tools such as SAP MDG, SAP ILM, OpenText or Business Partner/CVI
Experience working with systems integrators or managed service providers
A background in manufacturing or chemicals
The detail:
Permanent. Four days a week in the Kings Cross office. Applicants must have the existing right to work in the UK; sponsorship is not available.
