Company summary

Building a faster, lower cost, more commercial M&S :
Head office is where it all happens. The ideas, the imagination, the strategy, the vision. Everything, in fact, that makes M&S what it is today: a global multi-channel retailer which sets the standards others follow.
Working here means you’ll be at the forefront of our industry. So you’ll need to excel at what you do and share our passion for excellence, innovation and inspiring our customers.
We’re a big business with a huge range of opportunities for sharp, savvy commercial thinkers – and as we continue to evolve, there’ll be ever more ways for you to develop and grow
It is imperative that we simplify our culture – as this is the only way to drive change right through our business. We need to change our organisation, move on from the structure of a single business led by functional directors. This created a top-heavy business that was inward looking and too “corporate”.
All of our businesses sit under the M&S brand and are united by a common set of values, trading style, shared infrastructure and draw on the same customer data. Our focus remains to be an own brand retailer with quality, innovation, traceability and trusted value at our core. At the centre we are building a streamlined corporate team including a very strong data analytics and customer insight function.


Felxible Working
