(or whatever trendy buzzword we use for that role today)
My last two work experiences are:
Managing multiple Nomad-based cluster using the Nomad+Vault+Consul+Terraform stack. Making sure entire stack (and deployed workload) is monitored and observable.
Building and managing OpenStack cloud platform based on hundreds of physical hypervisors and CEPH storage. Heavily automated using Ansible, Puppet and GitOps approach.
I have experience with
Linux based system administration and deployment (Debian/Ubuntu server, CentOS/Alma)
platforms: OpenStack, Nomad, Docker, LXC and Kubernetes
