Marketing Assistant

Job Title: Marketing Assistant

Location: London – office based
Employment Type: Full-time

We are looking for an enthusiastic and hands-on Marketing Assistant to join our group marketing team. This is a junior role, perfect for a graduate or someone taking their first step into the marketing world. You’ll work closely with our UK and SA teams, and no two days will be the same – one moment you might be helping to set up a stand at an event, the next you could be supporting the team on major projects, and everything in between.

This is a truly varied, hands-on role where you’ll get exposure to all areas of marketing. No experience is required – we’re looking for someone who is tech-savvy, eager to learn, and ambitious. You’ll need a sharp eye for detail and a willingness to roll up your sleeves and get involved in whatever needs doing. If you’re the kind of person who sees a task and thinks “I can do that”, you’ll fit right in.

• Build, schedule, and send promotional email campaigns, including managing email lists and reporting on basic performance metrics.
• Create co-branded collateral for partners using existing templates, ensuring everything aligns with our brand guidelines.
• Provide light-touch design support for social assets, one-pagers, and sales decks – you should have a good eye for what looks polished and professional.
• Set up and update webpages using our content management system.
• Assist in setting up marketing workflows and automations, such as lead nurturing sequences.
• Ensure website content is accurate, up-to-date, and user-friendly.
• Support the team by building and formatting high-quality presentations in PowerPoint/Google Slides.
• Assist with ad-hoc administrative marketing tasks to keep the team running smoothly – from organising files to helping out at events.

• A proactive problem-solver who spots what needs doing and jumps in without being asked.
• Tech-savvy and comfortable picking up new software tools quickly – you enjoy figuring out how to make systems and processes work better.
• Strong attention to detail – you take pride in getting things right and feel confident checking and feeding back on other people’s work.
• A “no task is too small” attitude – you’re always happy to help, whether that’s building a presentation or setting up a stand at an event.
• Thrives in a fast-paced environment where priorities can shift – you’re adaptable and don’t get flustered by change.
• Ambitious and eager to learn – you see this as a stepping stone and want to grow with the team.

• No prior marketing experience needed – this role is open to graduates and first-jobbers.
• Basic familiarity with design tools like Canva is a plus (Adobe Creative Suite or Figma are not required but welcome).
• Comfortable using a CMS (like Word Press or Webflow) for basic page updates – or a willingness to learn quickly.
• Excellent written and verbal English communication skills.
• Strong proficiency in PowerPoint/Google Slides – you know how to make a presentation look clean and professional.
• A genuine enthusiasm for marketing and a hunger to develop your skills in a real-world environment.
