Social Media Manager

MARCHON is the UK’s premium performance-lifestyle ecosystem, one brand that helps driven people train, fuel and dress for a life without limits. World-class coaching sits at the centre, backed by certified performance nutrition and movement-ready apparel, all amplified by our beacon gyms. 

Founded by ex-England rugby player and CEO Ollie Marchon, the company has grown from a single HQ club to a true omni-channel offering: the Train app, a fast-scaling supplement line, and physical hubs that bring the experience to life.

We’re still small enough that every new teammate leaves fingerprints on the product, yet the momentum is real. Our 2026 plans are ambitious to say the least, as we make a step-change in evolving our ecosystem between training, supplements and apparel. 

If you care about high standards, straight talk and making a visible impact, you’ll feel at home here. Join us while there’s still room to shape the journey.
