We are Four, an international, independent agency powered by creativity and collaboration. Our 250‑strong team spans media, creative and communications, working from hubs in London, Cardiff, Sheffield and the UAE. Our award‑winning media team sits at the heart of the business, combining smart strategy, specialist tools and strong client service to deliver campaigns that get noticed and produce results. We work across a range of sectors, but this role sits within our healthcare media team, supporting campaigns for leading prescription medicines, medical devices and OTC brands.

As an Account Executive in our Paid Media team, you will help major healthcare and pharmaceutical companies shape treatment landscapes by reaching the doctors who rely on accurate, relevant information to support patient care. Your work will help ensure clinicians see and engage with information about medicines and treatments that can genuinely improve patient outcomes. You will be part of a team that takes accuracy, responsibility and impact seriously. This role is ideal for someone with energy, strong attention to detail and initiative who wants to learn fast, take ownership early and build a meaningful career in healthcare marketing. You will work closely with a senior member of the media team, supporting day‑to‑day activity across key accounts and gaining direct exposure to clients from the outset.

You will play a hands‑on role in the planning, activation and optimisation of paid media campaigns, ensuring everything runs smoothly and to a high standard.

Your Responsibilities Will Include:

• Supporting the smooth running of client accounts alongside the wider client team
• Assisting with planning and buying paid media campaigns across social and professional platforms
• Building and deploying campaigns across platforms such as LinkedIn, Meta and Google Ads
• Working directly with the ad operations team to build and deploy display media campaigns
• Monitoring performance and proactively suggesting optimisations to improve results
• Assisting in creating clear and accurate media plans
• Manipulating and analysing data to support performance reporting and insights
• Creating reports, providing commentary and optimisations, and presenting these to clients
• Attending meetings, capturing actions and following through on deliverables
• Liaising with publishers, creative agencies and internal teams to ensure campaign milestones are met
• Monitoring media and identifying opportunities or ideas for the wider team
• Developing an understanding of healthcare systems, pharmaceutical advertising regulations and relevant therapy areas

• Strong attention to detail and confidence working with numbers and data
• Clear written and verbal communication skills
• A positive, can‑do attitude and willingness to learn
