Join M&S and help shape the future of how we do business. 

This is a fantastic opportunity to join the Internal Audit & Risk (IA&R) team at M&S, where you’ll be at the heart of shaping how we do business. You’ll work across a wide range of areas in the UK and internationally, giving you real breadth and variety in your role. As a trusted advisor, you’ll review and challenge how the business operates, support improvements to the control environment, and make a tangible impact during an exciting period of transformation. 

What makes this role stand out is the mix of traditional audit delivery, augmented with data analytics, giving you exposure to every corner of the business from commercial operations to group functions. If you’re looking for a role that blends challenge, variety, and the chance to influence a leading brand’s journey, this is it.

• Engage stakeholders at all levels, presenting findings and driving improvements. 

• Contribute to audit planning, methodology evolution, and continuous improvement. 

• Working collaboratively with the risk team and other second line functions to bring insights and enhance the quality of audit work undertaken.

• Strong understanding of risk and control methodologies. 

• Experience or interest in data analytics
