Maintain and automate large-scale bare-metal infrastructure using MAAS/Ironic and Linux; design networks; automate provisioning (PXE/MAAS/Cloud-init) with Ansible/Bash/Python; deploy observability (Prometheus/Grafana, ELK/Graylog/Loki); integrate APIs and manage virtualization platforms like OpenStack, Proxmox, or VMware.

Maintain and automate large-scale bare-metal infrastructure using MAAS/Ironic and Linux. Design networks (VLANs, L2/L3, VPNs), provision servers (PXE/Preseed/Cloud-init), build observability (Prometheus/Grafana, ELK/Graylog/Loki), integrate APIs, and operate virtualization platforms (OpenStack/Proxmox/VMware).
