Role Overview:

AppSquadz Software is looking for a highly skilled Senior Data Center Engineer to lead the deployment, management, and scaling of our private cloud infrastructure in Noida. This role requires bridging the gap between physical hardware and virtualized resources. You will be responsible for the entire lifecycle of our OpenStack environment, leveraging KVM for virtualization and Ceph for software-defined storage. Your primary objective is to ensure high availability, optimal performance, and robust security for our mission-critical workloads.

Key Responsibilities:

• Architecture & Deployment: Design and deploy production-grade, highly available OpenStack clusters across multiple racks.

• Networking: Configure and troubleshoot Software-Defined Networking (SDN) using Open vSwitch (OVS) or OVN within the OpenStack Neutron framework.
• Infrastructure as Code: Automate server provisioning, configuration, and daily operations using Ansible, Terraform, or SaltStack.
• Storage Operations: Manage block, object, and file storage services, with a strong focus on Ceph integration with OpenStack (Cinder/Glance).
• Monitoring & Support: Implement proactive monitoring solutions (e.g., 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 for vendors like Dell, HPE, or Super-micro.

Required Qualifications:

• Experience: 5+ years in Data Center Operations or System Administration, with at least 3 years specifically focused on OpenStack.
• Linux Expertise: Expert-level proficiency in Ubuntu, RHEL, or Debian, including kernel tuning, system administration, 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 deployment).
• Experience with GPU pass-through for AI/ML workloads.
