Job Description: We're putting together a talented team to build the 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!

We're now looking ahead to the future and the people who want to help us build and scale Runna. Our aim is to reach millions of subscribers in the next 5 years and be the go-to training platform for any runner. Now is a magical time to join, we're still small, and everyone makes a foundational difference.

Who we're looking for

We are looking for talented, creative and positive team players to join our highly-skilled Cross-Functional Engineering Team to help deliver new features for our iOS, Android and Apple watch applications and third-party integrations (Garmin, Strava, Coros, Fitbit Suuntu etc). You will work closely with our founders and CTO to help shape the future of Runna, who will support you all along this exciting journey.

As a Software Engineer, your role will include:

Architect, build, test and deliver new features across the full stack
Work with the Product team to identify the most suitable solution for the best customer experience
Always be on hand to help other team members when they need help on technical matters
Help us operate more efficiently, by building and maintaining our developer tooling and CI/CD pipeline
We rotate the responsibility of releases across each team member, so you will get the opportunity to lead the process and deploy changes to production
