Role Overview

AVAR is looking for a highly skilled IT Engineer to take full ownership of its IT infrastructure design, implementation, and management. As part of our team in Head Office - Dubai, you'll work in an ONSITE environment applying a security-first mindset to architect and maintain our robust, enterprise-grade systems. This is a hands-on position with end-to-end responsibility, blending deep technical expertise in networking, system engineering, and information security. You will lay the foundation for and support a secure, resilient network that meets the needs of users across wired, wireless, and remote environments while driving best practices and compliance in all infrastructure operations.

Responsibilities

• Design and implement secure, segmented enterprise network infrastructure with multi-VLAN architecture.
• Configure Layer 2/3 switching, routing, and build core IT systems from the ground up.
• Deploy advanced network protection controls such as DHCP snooping, Dynamic ARP Inspection, and port security.
• Configure and manage next-generation firewalls, adopting a default-deny model and implementing threat protection mechanisms like IPS, antivirus, and application control.
• Enforce network access control and port-based authentication (802.1X) and dynamic VLAN assignment.
• Deploy and manage enterprise wireless solutions supporting corporate and secure guest networks.
• Implement secure VPNs with multi-factor authentication, ensuring remote access maintains consistent security standards.
• Design and manage Active Directory environments, DNS/DHCP integration, Group Policy, and RBAC.
• Implement endpoint protection, including disk encryption, application whitelisting, device control, and patch management.
• Define backup and disaster recovery strategies; conduct recovery tests and ensure data integrity is maintained.
• Maintain clear documentation (network diagrams, VLANs, firewall rules, runbooks), following structured change management processes.
• Ensure all infrastructure aligns with internal security policies and proactively address gaps while supporting audits.
• Provide direct hands-on support across systems, infrastructure, and end-user environments, leading incident response for IT outages and disruptions.
