* Troubleshoot complex issues across applications, Kubernetes environments, infrastructure, networking, identity services, databases, certificates, cloud services, and third-party integrations.
* Mentor engineers and partner with development, infrastructure, security, and business teams to improve technical standards, operational practices, documentation, release quality, and production readiness.
* Participate in a scheduled primary and secondary on-call rotation after completing training and demonstrating readiness to independently support the environment.
