We are looking for talented Principal Auditors to join our evolving Internal Audit team at an exciting time of development. In this role, you’ll deliver high-impact audit work across a diverse range of business areas, including model risk and credit risk, helping to ensure Nationwide continues to operate safely, sustainably, and in the best interests of our customers.

• Say it straight - We are brave in speaking out and saying what we think – we’re honest and direct with good intent, openly sharing diverse perspectives to reach the best conclusions and using language everyone can understand
• Push for better - We don’t settle for mediocrity, we challenge the status quo, taking responsibility for continuous improvement and personal development
