## About the Role

* Advanced hands-on experience designing, deploying, operating, troubleshooting, and scaling Ceph distributed storage environments supporting production virtualized workloads.
 * Advanced experience with Proxmox VE, including clustered virtualization, high availability, Ceph integration, networking, storage, lifecycle management, backup/recovery, and automation.
 * Advanced experience administering and troubleshooting OpenStack, including Nova, Neutron, Cinder, Glance, Keystone, compute infrastructure, networking, and Ceph integration.
 * Advanced experience with VMware vSphere, including ESXi, vCenter, HA/DRS, virtual networking, storage, lifecycle management, troubleshooting, and workload migration.
 * Expert-level Linux engineering skills with Red Hat-derived and Ubuntu distributions in large production environments.
 * Strong infrastructure-as-code and automation experience using Ansible, Terraform, Git, Python and/or Bash.
 * Strong infrastructure networking knowledge including TCP/IP, VLANs, routing, bonding/LACP, MTU, DNS, firewalls, virtual networking, and high-performance storage networks.
 * Experience designing and supporting bare-metal server infrastructure, including compute, storage, network interfaces, firmware, hardware lifecycle, and data-center deployment.
 * Demonstrated ability to perform large-scale virtualization and storage migrations, including discovery, capacity planning, dependency analysis, migration testing, rollback planning, and post-migration validation.
 * Strong understanding of high availability, backup/recovery, disaster recovery, capacity management, monitoring, performance tuning, security, and platform lifecycle management.

## Description

+ CephFS
 + RGW / object storage
 + CRUSH maps and failure domains
 + Pools, placement groups, replication and erasure coding
 * Diagnose:
 + degraded/undersized PGs
 + slow OSDs
 + recovery/backfill problems
 + capacity imbalance
 + latency and throughput bottlenecks
 * Understand storage networking, disk/SSD/NVMe characteristics, failure scenarios and performance tuning.
 * Ability to design Ceph for large production virtualization workloads, rather than simply administer an existing cluster.

 2. Proxmox VE: Advanced
Candidate should be able to:

 * Design and administer multi-node Proxmox VE clusters.
 * Deploy and manage KVM virtual machines.
 * Understand Proxmox clustering and quorum.
 * Integrate Proxmox with Ceph-backed storage.
 * Configure Linux bridges, VLANs, bonding, and storage/network separation.
 * Troubleshoot cluster, compute, storage, and VM problems.
 * Plan node maintenance and workload evacuation.
 * Design HA and failure-domain strategies.
 * Perform or plan migrations from VMware/OpenStack into Proxmox.
 * Understand backup/recovery architecture for Proxmox environments.
 * Automate VM provisioning and lifecycle management through APIs/IaC.

 3. OpenStack: Advanced
