Senior Server Engineer, Identity Platform

About This Role

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.

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.

We’re looking for a Senior Server Engineer to join our Identity Engineering Team, the group responsible for how every athlete securely accesses their Strava experience. Identity at Strava is more than login screens, it’s the platform that ensures trust, security, and continuity across all our applications and surfaces.

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.

What You’ll Do:

• Build core Identity platform capabilities, including authentication, authorization, token lifecycle management, session continuity, and account security systems.
• Develop scalable, reliable server-side services that support sign-up, login, account recovery, MFA/passkeys, and cross-application identity.
• Design and evolve modern identity protocols, integrating standards like OAuth 2.0, OIDC, WebAuthn, biometrics, and secure token exchange.
• Improve identity flows across iOS, Android, and web, balancing frictionless user experience with world-class security.
• Partner with cross-functional teams—Product, Security, Trust & Safety, Legal, and Mobile/Web Engineering—to build identity foundations that enable safety, privacy, and growth.
• Drive technical excellence, contributing thoughtful architectural perspectives and shaping long-term Identity strategies.
• Mentor and support fellow engineers, fostering a collaborative, inclusive, and high-trust environment.
• Influence system design across teams, using deep identity expertise to lead discussions around security, performance, and scalability.

What You’ll Bring to the Team:

• 7+ years of experience building production backend systems in languages such as Ruby, Java, Scala, Go, or Python.
• Proven experience with authentication, authorization, SSO, identity protocols, or account security systems at scale.
• Strong knowledge of distributed systems, relational/NoSQL databases, and technologies like MySQL, Redis, Cassandra, Kafka, or Kubernetes.
• Familiarity with or interest in modern identity technologies, such as OAuth 2.0/OIDC, WebAuthn, passkeys, MFA, and session management.
• A track record of building secure, high-performance services that handle sensitive data responsibly.
• Comfort navigating the intersection of security, user experience, and platform architecture.
• A collaborative spirit, someone who communicates clearly, lifts others up, and thrives in a team that values mentorship and learning.
