Assistant Marketing Manager

We’re looking for an Assistant Marketing Manager to help bring our brand to life through bold, stand‑out marketing. In this role, you’ll support the development and delivery of integrated brand campaigns that generate buzz, spark engagement, and strengthen how customers perceive our style, quality, and value. Working collaboratively across the business, you’ll help turn strategic priorities into compelling creative activity that cuts through, captures attention, and makes people stop and take notice. From shaping ideas through to supporting execution, you’ll play a key role in delivering marketing that is impactful, distinctive, and truly customer‑first. This is an exciting opportunity to join one of the UK’s most iconic retail brands and contribute to campaigns seen and loved by millions.

As part of our Campaigns team, you’ll support the delivery of brand‑building campaigns and seasonal activations, working closely with our creative agency and wider marketing teams to bring bold, integrated brand moments to life. You’ll be embedded in a fast‑moving, collaborative environment, partnering across multiple functions to ensure everything we put into the world is aligned, consistent, and unmistakably M&S, with creativity and commercial thinking at its heart. 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.

What’s in it for you: Being a part of M&S is exactly that – playing your part to bring the magic of M&S to our customers every day. We’re an inclusive, dynamic, exciting, and ever evolving business built on doing the right thing and bringing exceptional quality, value, service to every customer, whenever, wherever and however they want to shop with us. Here are some of the benefits we offer that make working for M&S just that little bit more special:

• After completing your probationary period, you’ll receive 20% colleague discount across all M&S products and many of our third‑party brands for you and a member of your household.
• Competitive holiday entitlement with the potential to buy extra holiday days!
• Discretionary bonus schemes awarded based on how you achieve your personal objectives and our performance as a business.
• A generous Defined Contribution Pension Scheme and Life Assurance.
• A dedicated welcome to our teams with a tailored induction and a wide range of training programmes to develop your skills.
• Amazing perks and discounts via our M&S Choices portal to maximise your financial and personal wellbeing.
• Industry‑leading parental, adoption, and neonatal policies, providing support and flexibility for your family.
• Access to a fantastic range of wellbeing support for all colleagues including access to our 24/7 Virtual GP and PAM Assist to support you and your family.
• A charity volunteer day to support a charity or cause you’re passionate about through a dedicated day away from work.

Your key accountabilities will include:

• Support the development of clear, insight‑led briefs for large‑scale, seasonal and BAU campaign activity.
• Collaborate with cross‑functional teams including Creative (+agency), Production, Media (+agency) PR, Social, Buying, Merchandising, and Internal Communications to ensure seamless end‑to‑end delivery.
• Ensure accuracy and consistency of product information, value messaging, and key claims across all creative assets.
• Manage creative feedback and approvals (via agency and internal systems), ensuring timely and aligned input from key stakeholders.
• Maintain accurate campaign documentation, timelines, and critical paths (e.g. MAP, Monday.com) to ensure delivery remains on track.
• Monitor and track campaign performance using PIRs and reporting dashboards.

Your skills and experience will include:

• Some experience in brand marketing, ideally within retail, fashion, or consumer goods, we value passion, curiosity, and creative instinct as much as years on a CV.
• Strong communication and interpersonal skills, with the confidence to build relationships across teams and engage effectively with external agency partners.
• You are a self‑starter who takes initiative and gets things moving – you spot what needs doing without being asked, and bring energy and ownership to everything you work on.
• You are naturally creative and curious – you look for fresh angles, bring innovative thinking to briefs, and have an instinct for what will resonate with customers.
• You have a genuine curiosity about consumers, culture, and the media landscape – you stay on the pulse of trends and use insight to shape more impactful, relevant work.
