Supply and Demand Manager

We’re reshaping our Food business to broaden its appeal, protecting the magic our customers love while modernising everything else. That means outstanding quality, high sourcing standards, and market‑leading innovation remain at our core, while we transform our supply chains, improve our stores, and deliver better value. We’re looking for motivated people ready to bring their whole self to work and thrive in a fast‑paced, ambitious team.

We are recruiting for two Supply and Demand Managers: one in Ambient and the other in Chilled. Categories will be confirmed on or after offer. As a Supply and Demand Manager, you will be right at the heart of a supply chain undergoing significant transformation. You will lead a large team, set the pace and build an environment where people feel supported, challenged and motivated to deliver at their best. You will work closely with senior leadership, bringing clarity to performance, making confident decisions and keeping things moving in a fast, demanding environment.

This is a role where you stay close to the detail, act quickly when issues arise and take real ownership when things do not go to plan. You will balance availability, waste and service in a complex, fast‑moving environment, working across multiple categories and suppliers. Alongside this, you will drive planning with suppliers, commercial teams and retail to support launches, promotions and range changes. With RELEX, our market‑leading forecasting system built around M&S, you will help shape a more responsive, data‑led supply chain that supports our growth ambitions.

This role requires you to be on site in our Support Office in Paddington, London for three days a week. We know that will not suit everyone, and that is okay. If you are looking for a fully remote role, this will not be for you. But if you believe in the power of working together in person to solve problems, share ideas, and shape the future of food, we would love to hear from you. Due to high interest, this role may close earlier than advertised. We recommend applying as soon as possible.

What you’ll do

• Lead and inspire a team of planners to deliver exceptional product availability, while minimising waste and optimising inventory levels, embedding consistent ways of working and high performance.
• Drive collaborative planning with commercial, food technical and product development teams to support new launches, seasonal shifts and promotional activity.
• Translate data into action, influencing ranging, facings and distribution decisions to improve trade and reduce waste across stores.
• Own long‑range forecasting and supplier performance, using RELEX and Excel to anticipate demand and ensure delivery in full.
• Build strong supplier relationships and respond quickly to change, helping shape major transformations and keep products on shelf for our customers.

Who you are

• A confident and inclusive leader with experience managing teams, able to coach, mentor and guide others through challenge, change and growth.
• A clear and persuasive communicator who adapts their style to different stakeholders, using insight and data to influence decisions and drive action.
• Structured and organised, with a methodical approach to planning, prioritisation and execution in a fast‑paced environment, working with multiple teams and partners.
• Technically capable, with a working knowledge of supply chain systems, forecasting tools and Excel; experience with RELEX or similar platforms is a plus.
• Commercially curious and future‑focused, able to align supply chain activity with long‑term business goals and deliver performance through people; retail experience is helpful but not essential.

What’s in it for you?

Working at M&S means being part of something bigger – helping to deliver quality, value and service to millions of customers every day. We’re inclusive, fast moving and always evolving, with a strong sense of purpose and a focus on doing the right thing. Here are just a few of the benefits that make working here even more rewarding:

• 20% colleague discount on all M&S products and many third party brands for you and someone in your household, available once you’ve completed your probation.
• Competitive holiday allowance with the option to buy more.
• Discretionary bonus schemes linked to your performance and ours.
• Strong pension and life assurance to help plan for the future.
• Tailored induction and training to support your development from day one.
• Exclusive perks and savings through our M&S Choices portal.
• Market leading family policies, including parental, adoption and neonatal leave.
• 24/7 wellbeing support, including virtual GP access and mental health services.
