Software Engineering Intern, App

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

We help everyday runners become outstanding by building an incredible app providing world-class training, coaching and community for everyone, whether you're improving your 5k time or training for your first marathon.

We’re growing extremely fast! In November 2023 we closed a $6.5M funding round led by JamJar with participation from Eka Ventures, Venrex and Creator Ventures. In 2024, we were selected by Apple as one of three global finalists for the iPhone app of the year, reflecting the innovation and impact of what we’ve built & in 2025 we were acquired by Strava!

Our ambition is huge: to become the go-to global leading training platform for millions of runners everywhere. We’re growing with purpose and looking for people who want to build something meaningful with lasting impact. With the recent acquisition by Strava accelerating our journey, now is a really magical time to join. 🚀

We are looking for talented, creative and positive team players to join our highly-skilled cross-functional engineering team. You’ll be jumping into the App Team where you’ll work closely with engineers, product managers and designers to ship quality features that scale. Along the way you’ll be closely supported by our engineering leadership team and CTO, all while being given the space to take real ownership of what you’re delivering.

We have a jam packed roadmap, with countless opportunities to champion new technologies, work on meaningful problems that impact millions of runners, and improve existing architecture to elevate the whole of our engineering team.
