Senior Platform Engineer, Runtime (Auth0)

The Auth0 platform secures more than 100 million logins each day for customers all around the world - and we're growing fast! The Platform Runtime team enables Auth0 engineers to move faster by giving them the foundational infrastructure to deploy and manage their services on AWS and Azure. This is a role with a huge impact. You will get to work with engineers throughout the organization and what you build will be a foundational piece of the infrastructure that allows Auth0 to scale for years to come.

We are looking for a Senior Engineer who is passionate about distributed systems, availability, and delivering customer value. Because we build and support the overall Auth0 platform, the ideal candidate is someone who is passionate about low level infrastructure, operations, and not intimidated by cross-organization coordination and collaboration.

• Serve as the ultimate technical authority and final escalation point for advanced Kubernetes cluster troubleshooting, ensuring the continuous stability and resilience of our foundational infrastructure.

• Develop and maintain application deployment standards, managing Kustomize and built-ins to standardize and streamline deployments across all product teams.
• Orchestrate complex GitOps workflows leveraging ArgoCD and Argo Workflows. You will take full ownership of Environment Lifecycle Management, handling everything from environment creation, synchronization, and user onboarding to failover procedures and safe deletion.
• Architect the Testing Automation Framework to support dynamic environment provisioning and destruction. This will enable advanced quality assurance practices, such as chaos testing, while empowering teams to manage their own test workflows.
