As a Staff Software Engineer on GitLab's Authentication team, you'll be the technical lead for how every user, application, token, and automated agent proves who it is on GitLab.com, Self-Managed, and Dedicated.
We're an OAuth 2.0 and OpenID Connect (OIDC) provider for millions of users. We also accept identity from enterprise identity providers through Security Assertion Markup Language (SAML) and Lightweight Directory Access Protocol (LDAP). Behind that sit more than ten token types and several session methods that grew inside the Ruby on Rails monolith. You'll help us move this work onto GATE, GitLab's new authentication and authorization platform. GATE exchanges external credentials for short-lived tokens at the edge through a Secure Token Service written in Go.You'll set our technical direction, lead the hardest protocol and migration work yourself, and help senior engineers own the rest.
Our projects include:
The Authentication group is part of the Security Platform stage, alongside Authorization, GATE Core, GATE Infra, Secrets Manager, and other security teams. We own sign-in, single sign-on, OAuth, and personal and service tokens. Our work touches every GitLab customer, and much of it is on the critical path for Cells and for GitLab's AI agent platform.
