Financial Services Swindon, Wilts 10,001+ employees Founded 1846 Privately Held

Nationwide is a 10,000+ employee mutual bank headquartered in Swindon, operating across retail mortgages, savings, credit, and insurance. The tech stack reveals mid-stage enterprise modernization: Pega (workflow), SAP Fiori (UX layer), and SAS/Databricks (analytics) sit alongside older ABAP and SQL systems. Active S/4HANA adoption and projects titled 'reimagining core banking technology landscape' and 'consolidating systems into unified SAP ecosystem' signal a multi-year platform migration to replace fragmented legacy infrastructure. Support hiring (9 open roles) outpaces engineering (2) — typical for organizations in heavy operational transition.
