Description

Responsibilities

• Design, implement, and operate virtualized infrastructure using VMware vSphere, Proxmox VE, and OpenStack for Linux, Windows, and Windows Server workloads.
• Build and automate OS provisioning and golden images across hypervisors and cloud platforms (templates, cloud‑init, scriptsetc.).
• Configure and manage core services including DNS, DHCP, NTP, Active Directory/LDAP, and IAM/AAA (RBAC, SSO,MFA).
• Deploy, upgrade, and operate Kubernetes clusters (on-prem and managed services such as OpenShift, AKS, EKS, GKE), including worker lifecycle, CNI, ingress, and basic storage integration.
• Support and administer public cloud environments on Azure, AWS, and GCP (focus on compute, networking, storage, IAM, and cost awareness).
• Administer Cisco network switches, routers, and firewalls, including VLANs, routing, VPNs, ACLs, and firewall policies in line with security standards.
• Collaborate with storage teams to provision and consume SAN/NAS resources; understand RAID, LUNs, snapshots, backup/restore, and capacity/performance considerations.
• Implement OS and infrastructure security controls, including hardening, patching, endpoint security, and firewallrules.
• Produce and maintain low‑level designs and accurate network and system diagrams using Visio, draw.io or equivalenttools.
• Monitor infrastructure health, capacity, and performance; troubleshoot complex incidents across compute, network, storage, and cloud layers; drive root‑cause analysis and remediation.
• Adhere to ITIL practices for Incident, Problem, and Change Management; create and update tickets in ServiceNow or equivalent ITSMtools.
• Prepare and present changes in CAB meetings, including risk, impact, test, and rollbackplans.
• Create and maintain technical documentation, runbooks, and standard operating procedures for all supported platforms and services.
• Collaborate with cross‑functional teams (security, development, operations) to ensure reliability, performance, and security of services.

Preferred Skill Set

Primary

• Strong hands‑on experience with Cisco, VMware vSphere (ESXi, vCenter) and at least one of Proxmox VE or OpenStack.
• Solid administration experience in Linux (RHEL/CentOS/Ubuntu) and Windows Server (installation, configuration, hardening, troubleshooting).
• Working knowledge of Azure and AWS (VMs/EC2, VPC/VNet, security groups/NSG, IAM, storage, load balancers); familiarity with GCP/GKE is highly desirable.
• Experience deploying and operating Kubernetes clusters on-prem and in the cloud (AKS/EKS/GKE), including basic observability and backup concepts.
• Good understanding of networking fundamentals: TCP/IP, VLANs, routing, switching, DNS, VPN, load balancing, and firewall concepts.
• Practical experience with Cisco networking and enterprise firewalls (e.g., Cisco ASA/FTD or equivalent).
• Understanding of storage fundamentals (SAN, NAS, iSCSI, NFS, RAID levels, snapshots, replication).
• Ability to create clear, accurate, and supportable network and infrastructure diagrams and documentation.
• Familiarity with ITIL processes and hands‑on use of ServiceNow or similar ITSM platforms; prior CAB participation is an advantage.
• Strong analytical and troubleshooting skills, ability to handle high‑severity incidents, and perform structured root‑cause analysis.
• Excellent communication skills, with the ability to collaborate across teams and present technical topics to non‑technical stakeholders
