Job Description

FitXR is a fitness technology company working at the cutting edge of VR and MR. We’re a funded scale-up on a mission to impact more lives than any other fitness company, and build a healthier world for everyone.

We started life in 2016 in a garden shed in the UK. Today, we’re building FitXR, one of the top-downloaded apps on the Meta Quest store. We’ve raised close to $40m from top investors such as Maveron, Hiro, BoostVC and TriplePoint.

We’re a remote-first team of just under 100 people from across the US, UK, and Spain, and we’re committed to making it simpler and more enjoyable for people to get moving. We believe that anybody can fall in love with fitness and make movement part of their life.

Our team is distributed across Europe and the US. We’re guided by our Principles of Play: eight core beliefs about how we treat each other and our community. We make space for every voice, believe in the importance of a learner’s mindset, and prioritize team success over individual glory.

The FitXR app contains a growing range of fitness studios, where members can choose from box workouts with world-class trainers like Olympian Nicola Adams, powerful HIIT workouts, and immersive dance classes. While nothing compares to trying it yourself, you can watch a trailer here.

FitXR is available on Meta Quest 2 and has been downloaded by over a million people worldwide. Featured in Forbes, Empire, T3, Washington Post, Men's Health, GQ and more. In 2022, FitXR ranked 6th in The Information’s 50 Most Promising Startups.

The FlexScore® is the result of a rigorous 2-step verification of a company’s flexibility

First we assess the flexibility options FitXR provides and then we anonymously survey a statistically significant proportion of their employees to make sure FitXR is as flexible as they say they are. Our assessment is based on the six key elements of flexibility: location, hours, autonomy, benefits, role modelling and work-life balance.

We ask the hard questions so you don’t have to.
