With the most comprehensive collection of trails in the world, AllTrails supports inclusive access to nature for a global community of millions of trailgoers. Every day, we solve incredibly hard problems to get more people outside, for their wellbeing and the collective care of the natural world. Join us!

This is a U.S. based remote position. While this role does not require in-person attendance, we have a preference for candidates based in or near one of these cities: San Francisco CA, Portland OR, Seattle WA, Denver CO, and New York NY. Being in one of these cities creates opportunities to connect with teammates through Trail Days, co-working sessions, and local gatherings while still having the flexibility to work remotely. San Francisco employees are highly encouraged to come to the office one day per week.
