About The Position

Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era. This work requires a relentless drive to solve complex challenges with real-world stakes. We are looking for builders and owners who operate with speed and urgency and execute with excellence. This is an opportunity to do career-defining work. We're all in on this mission. If you are too, let's talk. The Core Service Interfaces Team owns the building blocks and core services that power how developers and administrators interact with Auth0, from the customer-facing Management API to the backend that drives the Management Dashboard. We streamline and bring consistency to how we build customer facing APIs for Auth0, standardizing our architecture and providing a robust set of building blocks to enhance the internal and external developer experience when consuming, building, and contributing to our APIs. We are responsible for the development and stewardship of our customer facing Management API. We also own and maintain the core backend services for the Management Dashboard, from end to end. We are consolidating and modernizing the dashboard foundation, moving toward a more reliable, scalable, and secure platform that makes dashboard development easy. This team's work shapes how developers get started with and manage their Auth0 resources, from onboarding through day-to-day administration of their APIs and dashboard. We have embraced AI-assisted development as a core part of how we work. Our engineers use tools like Claude and GitHub Copilot every day to design, build, test, and ship faster, and we expect everyone on the team to make the most of them.
