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.

• Experience operating in a structured IT environment with change, incident, and problem management processes.
• Ability to troubleshoot complex network and security issues under pressure.
• Experience supporting network security controls in public cloud environments (AWS, Azure, and/or OCI).
