This requires strong Linux system administration and problem-solving skills to ensure stability during our transition to cloud-native workflows. The software development portion of this role is centered on creating internal tools to improve system management, automate operational tasks, and build out our observability stack. Your success in this area is critical for establishing meaningful SLIs and achieving our reliability targets.
