About The Position

The Privacy and Identity team owns how every athlete securely accesses their Strava experience and builds the tools that help them understand and manage their privacy on Strava, from account security to giving people clear visibility into and control over their data across iOS, Android, and web. We're looking for a fullstack engineer to help build and improve the systems that keep athlete accounts secure and easy to access. You'll work across mobile, web, and server, contributing to sign-up, login, password management, account recovery, and privacy controls. This role will span work across platforms and key product surfaces. No prior identity or authentication experience is required, just strong product engineering fundamentals and a willingness to learn quickly in a high-trust domain. We follow a flexible hybrid model that translates to more than half of your time on-site in our San Francisco office, three days per week.
