Meet the Team

A group of colleagues gathered around a table, smiling and discussing work with laptops open in a modern office setting.

Being an in-person business

We're at our best when we're close to customers, and for many of us at M&S, that means working in store every day.

To stay close to customers, our support teams are in the office three days a week as we believe that skills are developed through collaboration, and that spending time together makes us more creative and connected. It also means we can solve problems as soon as they arise, learn and grow as a team, build trust, and get closer to our colleagues.

Halford Head of Technical Program Management

Being in third-party brands, working on things M&S hasn’t done before… that plays to my sweet spot. I’ve worked in many organisations throughout my career, and it’s rare to see such cause and effect in your work. The way we’re structured means you’re encouraged to solve problems and you have the autonomy to make progress quickly.

At M&S, we have Data Scientists, Analysts, and Technical Product Managers, who all share a genuine passion for harnessing data to improve people’s lives. And we’re in a unique position where we can actually help many different kinds of people, from our customers to our colleagues in store and in our support centre.

Deepak (He / Him) | Data Scientist Read full story

I think all engineers just love solving puzzles and problems. At M&S, we’re constantly learning new things, whether it’s mastering Swift UI or understanding how customers interact with technology. But this is also a business that listens to engineers and values what we bring to the table. That’s different, believe me.
