The Fast 800 is at a pivotal and exciting stage of growth. We are a science‑led online health business with a loyal global community, a trusted legacy through Dr Michael Mosley, and a clear mission: to help people improve their health through evidence‑based nutrition, behaviour change and practical support that works in real life.
As we continue to grow our programme, products and digital presence, we are looking for an experienced Social Media & Content Manager to join our small, friendly and highly collaborative UK‑based team.
This is a brilliant opportunity for someone highly creative, proactive and commercially minded to help shape the voice of the brand, grow our community and create content that genuinely inspires people to take action with their health.
Reporting to the Senior Brand Manager, this is a high‑energy, “hands‑on” role designed for a creative storyteller who lives and breathes social media. You’ll be the engine room behind our organic growth, leading the strategy and execution across all social channels while working closely with team members as well as the Mosley family to build The Fast 800 community.
From scripting and filming high volumes of short‑form video to brainstorming the next viral campaign or competition, you’ll turn our brand mission into engaging, thumb‑stopping content. You’ll also be Mat leave caretaking a role in our paid digital strategy, testing new hooks and creative assets to see what truly resonates with our audience.
Ultimately, you’re here to bridge the gap between big‑picture brand goals and daily community engagement, ensuring our voice is consistent, our content is fresh, and our reach is constantly expanding.
