Resolve complex LAN, WAN, cloud, and firewall issues to maintain business continuity.
Drive automation and operational efficiency using tools such as Python, Ansible, Terraform, and PowerShell.
Create and maintain technical documentation, network diagrams, security standards, and operational procedures.
Mentor engineers and contribute to continuous improvement initiatives across the wider technology team.

What We're Looking For:

Minimum of 8+ years' experience in Network Engineering, Cloud Networking, and Network Security.
Strong expertise across:
Cisco Networking & Routing/Switching
- Palo Alto, Check Point, Cisco ASA, and ForeScout
- F5 Load Balancing
- Infoblox DNS/DHCP/IPAM
- AWS, Azure, and/or GCP Networking
Hands-on experience with vulnerability management, patching, firmware upgrades, and compliance controls.
Strong understanding of network security principles, Zero Trust Architecture, SD-WAN, and micro-segmentation.
Experience with Infrastructure as Code (IaC) and network automation.
Excellent troubleshooting, stakeholder engagement, and communication skills.
Experience working in complex enterprise or multi-cloud environments.

Desirable Experience:

SIEM, IDS/IPS, and endpoint security integration.
Network monitoring and observability tools such as SolarWinds, LogicMonitor, Splunk, BigPanda, or Wireshark.
