The Role

The Network Engineer is responsible for the operational support, maintenance, patching, and lifecycle management of Fortinet firewall platforms across on-premise and cloud environments. The role ensures the security, availability, and performance of network security controls, supporting business resilience and regulatory compliance.

As parts of the firewall estate are cloud-hosted, the role also requires practical experience across public cloud platforms, with exposure to infrastructure-as-code practices being desirable.

Key responsibilities:

• Provide day-to-day operational support for Fortinet firewall platforms (e.g. FortiGate, FortiManager, FortiAnalyzer).
• Plan and execute firewall patching, firmware upgrades, and vulnerability remediation in line with change and release processes.
• Monitor firewall health, performance, and capacity, proactively identifying and resolving issues.
• Implement, review, and maintain firewall policies, NAT rules, and routing configurations in accordance with security standards.
• Support incident response and problem management activities relating to network security events.
• Support Fortinet firewalls deployed in cloud environments, including AWS, Azure, and OCI.
• Assist with the design, deployment, and maintenance of secure network connectivity between on-premise and cloud environments (e.g. VPNs, routing, segmentation).
• Work closely with cloud, DevOps, and security teams to ensure consistent network security controls across hybrid estates.
• Ensure all changes align with organisational security policies, architectural standards, and regulatory requirements.
• Produce and maintain clear technical documentation, including network diagrams and operational runbooks.
• Collaborate with internal stakeholders and third-party suppliers to deliver secure and reliable network services.
• Participate in on-call or out-of-hours support, where required.

Your Profile

Essential skills/knowledge/experience:

• Strong hands-on experience supporting Fortinet firewall technologies in a production environment.
• Proven experience with firewall patching, upgrades, and lifecycle management.
• Solid understanding of networking fundamentals (TCP/IP, routing, VPNs, DNS, load balancing).
• Experience operating in a structured IT environment with change, incident, and problem management processes.
• Ability to troubleshoot complex network and security issues under pressure.

Desirable skills/knowledge/experience:

• Experience supporting network security controls in public cloud environments (AWS, Azure, and/or OCI).
• Exposure to Infrastructure as Code, particularly Terraform.
• Familiarity with cloud-native networking constructs (e.g. VPCs/VNETs, routing tables, security groups).
