Platform Engineer

We’re putting together a talented team to build the #1 training platform for Runners

We help everyday runners become outstanding by providing world-class training, coaching and community for everyone, whether you’re improving your 5k time or training for your first marathon. To date we have built iOS, Android and Apple watch apps that help people achieve their goals by coaching them through the full journey and syncing to their favourite fitness devices.

We’re growing extremely fast and in November 2023 closed a new £5M funding round led by JamJar with participation from Eka Ventures, Venrex and Creator Ventures. And in 2024, we were selected by Apple as one of three global finalists for the 2024 iPhone App of the Year reflecting the innovation and impact of what we’ve built.

We want to grow as fast as we can into the future and are looking for individuals who will help us get there. For more about our background and growth check out our Careers Page!

Our aim is to reach millions of subscribers in the next 5 years and be the go-to training platform for any runner.
