• Solid knowledge of Ubuntu Linux administration and VM management.
• Familiarity with Linux networking concepts including bridges, VLANs, bonding, and IP addressing.
• Scripting skills in Bash, Python, or similar languages.
• Experience with virtualization concepts: KVM, QEMU, PCI passthrough, NUMA, and resource isolation.
• Ability to troubleshoot hardware and software performance issues related to networking and virtualization.
• Good understanding of security in virtualized and cloud environments.
• Familiarity with monitoring tools (e.g., Prometheus, Grafana) is a plus.

Preferred Qualifications:

• Background in telecom or data center networking environments.
• Familiarity with CI/CD pipelines and GitOps workflows.
• Experience with cloud platforms (AWS, Azure, GCP) in hybrid setups.

Education & Experience:
