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. 

Key Responsibilities 

• 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. 
   

What We’re Looking For: 

• 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. 

Required Skills & Experience 

• 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 WordPress 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.
