Senior Site Reliability Engineer - Managed Kubernetes

Role description

Role Overview

As a Senior Site Reliability Engineer at Lambda, you will operate and maintain bare-metal Kubernetes clusters, scaling up to thousands of nodes, and handle cluster degradation, recovery, resizing, and incident response using fleet management tools.
