About the Role

We are seeking an experienced Network Security Engineer to join a major organisation in Abu Dhabi, working on a large‑scale, cloud‑first security transformation. This is a hands‑on engineering role focused on SASE, Zscaler (ZIA/ZPA), FortiGate firewalls, and enterprise Wi‑Fi security.

You’ll be responsible for designing, deploying, and operating secure network architectures across on‑prem, cloud, and remote environments – with full ownership rather than simply maintaining existing platforms. If you enjoy building, optimising, and securing modern network environments end‑to‑end, this role will suit you perfectly.

Key Responsibilities

Zscaler (ZIA & ZPA) / SASE

• Lead deployment and daily operations of Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA)
• Design traffic forwarding architectures (GRE, IPsec)
• Manage identity and authentication integrations
• Configure and maintain Zscaler security controls:
  • URL filtering
  • Cloud firewall
  • SSL inspection
  • Threat prevention
  • Access control
• Onboard new users and sites, supporting remote and branch connectivity
• Optimise local internet breakout and cloud‑first routing

Network Security / FortiGate

• Deploy and manage FortiGate firewalls
• Design and maintain policies, NAT, VPNs, and routing (BGP/static)
• Integrate FortiGate with Zscaler for secure egress and private access

Enterprise Wi‑Fi Security

• Support rollout and configuration of secure enterprise Wi‑Fi
• Design SSIDs, segmentation, and authentication (including 802.1X)
• Troubleshoot performance, coverage, and connectivity issues

Cross‑Domain Troubleshooting

• Diagnose complex issues across cloud, on‑prem, and remote environments
• Work across networking, security, and user connectivity
• Own deployments end‑to‑end

Ideal Candidate (Requirements)

• Strong hands‑on experience with Zscaler ZIA & ZPA
• Solid operational knowledge of FortiGate firewalls
• Experience with enterprise Wi‑Fi security
• Comfortable designing and deploying secure, cloud‑first architectures
• Strong troubleshooting skills across multi‑layered environments
• Able to take ownership of deployments, not just maintain existing systems

If interested, please apply and a consultant will be in touch ASAP!
