Strava is the app for active people. With over 150 million athletes in more than 185 countries, Strava is where connection, motivation, and personal bests thrive. No matter your activity, gear, or goals, we help you find your crew, crush your milestones, and keep moving forward. 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.

At Strava, we protect the infrastructure that powers millions of athletes' journeys. As a Senior Infrastructure Security Engineer on the Foundation Team, you'll be the guardian of our platform—building security into every layer of our infrastructure while enabling teams to move fast and innovate fearlessly. You'll balance security excellence with developer velocity, ensuring our platform remains both impenetrable and performant.

The Foundation Team is the backbone of Strava's engineering organization, providing the secure infrastructure, tools, and frameworks that power every feature our athletes love. In this role, you'll embed security into the foundation of our platform—from hardening our Kubernetes clusters and cloud infrastructure to building automated security guardrails that make the secure path the easy path for developers.

By architecting security solutions that scale, you'll protect the data of 150+ million athletes while enabling product teams to ship features with confidence. You'll be both a builder and a defender—creating tools that empower engineers, responding to emerging threats, and partnering across Strava to weave security into our engineering DNA.

We follow a flexible hybrid model that translates to more than half your time on‑site in our Denver office—three days per week.

• Create and operate the infrastructure that makes Strava possible, from data stores and the container platform to observability software and deployment tooling.
