About the role

We are seeking an experienced Infrastructure Engineer to manage, maintain, and optimize our enterprise network and virtualization infrastructure. The role covers end-to-end administration of Cisco network switches, routers, and firewalls, as well as VMware virtualization platforms and associated storage systems. The ideal candidate combines strong hands-on technical skills with a proactive approach to configure monitor, capacity planning and documentation of core IT infrastructure.

What you'll do

Network Infrastructure

• Install, configure, and maintain Cisco switches and routers across LAN/WAN environments.

• Manage routing protocols VLANs, trunking, spanning tree, and inter-VLAN routing.

• Configure and administer Cisco firewalls, including access control policies, NAT, site-to-site and remote-access VPNs.

• Monitor network performance, troubleshoot connectivity and latency issues, and perform root-cause analysis.

• Implement network segmentation, QoS policies, and security hardening in line with best practices.

• Maintain firmware/IOS upgrade cycles, configuration backups, and change control for all network devices.

Server & Storage

• Administer On-prem VMware vSphere environments, including ESXi hosts, vCenter Server and resource pools.

• Manage VM lifecycle: provisioning, templates, snapshots, migrations (vMotion/Storage vMotion), and decommissioning.

• Perform configurations, performance tuning, monitoring and patch management.

• Support backup and disaster recovery solutions for virtualized workloads (e.g., Veeam or equivalent).

• Administer SAN/NAS storage platforms (e.g., Dell EMC) including LUN provisioning, zoning, and datastore management.

• Manage storage connectivity (iSCSI, Fibre Channel, NFS) between storage arrays and the VMware environment.

• Monitor storage capacity, IOPS, and latency; plan expansions and optimize utilization.

• Implement and test storage-level replication, snapshots, and data protection policies.

General Infrastructure & Operations

• Respond to incidents and service requests within defined SLAs; participate in on-call rotation as required.

• Maintain accurate infrastructure documentation: network diagrams, IP address management, runbooks, and configuration standards.

• Collaborate with security, application, and vendor teams on projects, upgrades, and audits.

• Support datacenter operations, including hardware installation, cabling, and environmental monitoring.

• Contribute to infrastructure improvement initiatives, automation (scripting), and technology refresh planning.

Qualifications

• Bachelor's degree in Computer Science, Information Technology, or a related field (or equivalent practical experience).

• 5+ years of hands-on experience managing enterprise network and virtualization infrastructure.

• Strong expertise in Cisco networking: switching, routing, and firewall administration.

• Proven experience administering VMware vSphere (ESXi, vCenter) in production environments.

• Solid working knowledge of enterprise storage technologies (SAN/NAS, iSCSI, FC, NFS).

• Strong understanding of network security principles, VPNs, and access control.

• Experience with monitoring and management tools (e.g., SolarWinds, PRTG, vRealize/Aria Operations).

• Excellent troubleshooting, analytical, and documentation skills.

Preferred Certifications

• Cisco CCNA required; CCNP (Enterprise or Security) preferred.

• VMware VCP-DCV (Data Center Virtualization).

• Storage vendor certification (e.g., NetApp NCDA, Dell EMC) is a plus.

• ITIL Foundation is an advantage.

Desirable Skills

• Scripting/automation experience (PowerShell, PowerCLI, Python, Ansible).

• Experience with backup solutions (Veeam, Commvault) and DR planning.

• Familiarity with Windows Server and Active Directory environments.

Soft Skills

• Strong communication skills and ability to work with cross-functional teams and vendors.

• Self-driven, with the ability to prioritize and manage multiple tasks in a fast-paced environment.

• Commitment to reliability, security, and continuous improvement.

Working Conditions

• On-call availability for critical incidents and scheduled maintenance windows (evenings/weekends as needed).

• Onsite required: Monday - Friday, 8am-5pm
