About Strava

Strava is the app for active people. With over 180 million athletes in more than 185 countries, it’s more than tracking workouts—it’s where people make progress together, from new habits to new personal bests. No matter your sport or how you track it, Strava’s got you covered. Find your crew, crush your goals, and make every effort count. Start your journey with Strava today.

Our mission is simple: to motivate people to live their best active lives. We believe in the power of movement to connect and drive people forward.

As an Engineering Intern at Strava, you will be embedded in a team working on real projects that ship to our athletes and within the company, treated like a full-time member of the engineering team. You'll collaborate with cross functional teams that help us support and deliver to our athletes faster, while keeping them inspired and motivated.

We’ll give you experienced mentors and all the tools you need to make a meaningful impact on our product. To see examples of what past interns have contributed, read our Engineering Blog!
