We are seeking a highly skilled Data Center Engineer to lead the deployment, management,

integration with OpenStack (Cinder/Glance).

Monitoring & Support: Implement proactive monitoring (Prometheus/Grafana or ELK stack) and

participate in an on-call rotation for critical infrastructure incidents.

Hardware Lifecycle: Oversee physical server installation, firmware updates, and hardware

troubleshooting (Dell, HPE, or Supermicro).

Required Qualifications:

Experience: 5+ years in Data Center Operations or System Administration, with at least 3 years

focused on OpenStack.

Linux Expertise: Expert-level proficiency in Ubuntu, RHEL, or Debian (Kernel tuning, systemd,

and LVM).

Virtualization: Deep understanding of KVM and the ability to troubleshoot VM-to-Hypervisor

communication.

Networking: Strong grasp of Layer 2/Layer 3 networking, VLANs, VXLAN, and BGP.

Scripting: Proficiency in Python or Bash for automation and tool development.

Problem Solving: Proven ability to debug complex "distributed system" issues where the root

cause could be hardware, network, or software.

Preferred "Bonus" Skills

Certified OpenStack Administrator (COA) or Red Hat Certified Specialist in Cloud Infrastructure.

Experience with Kubernetes (K8s) running on top of OpenStack (Magnum or manual).

Experience with GPU passthrough for AI/ML workloads.
