Auth0 is an identity and access management platform built for developers. Based in Bellevue, Washington, it provides the backend infrastructure for authentication, authorization, and single sign-on. Instead of building login systems from scratch, engineering teams use Auth0 to handle multifactor authentication and OAuth/OIDC across their web, mobile, and IoT apps. Okta acquired the company in 2021. Internally, Auth0's culture leans heavily on developer experience. Product, security, and developer advocacy teams work closely together, mostly because their end-users are other developers trying to integrate an API. For engineers looking to work there, the main draw is the sheer scale of the traffic. The job offers hands-on experience with high-availability systems that major enterprises rely on globally. It's a practical place to specialize in security and identity tech while building tools that other developers actually enjoy using.
