We are looking for a skilled Network Security Engineer with a strong focus on firewall technologies to join our IT Infrastructure team. This role is centered on the design, implementation, and day-to-day operation of enterprise firewall platforms, ensuring secure, reliable connectivity across our business.

You will play a key part in maintaining and improving our perimeter and internal network security controls, supporting both operational stability and project delivery. The role combines hands-on technical work with the opportunity to influence firewall architecture, standards, and long-term security posture.

Key Responsibilities

Operate and maintain enterprise firewall platforms, ensuring secure, reliable connectivity across IT and OT environments
Design and implement firewall rules, NAT, and segmentation to support business and industrial systems
Lead firewall changes and troubleshooting, acting as the senior escalation point for complex network security issues
Drive continual improvement of firewall policies, focusing on rule optimisation, hygiene, and risk reduction
Support network design and security controls, with a focus on firewall placement, segmentation, and traffic control
Work closely with infrastructure, OT, and application teams to enable secure and resilient connectivity
Deliver firewall and network-related projects, including upgrades, migrations, and new site deployments
Provide technical oversight of third parties, ensuring firewall and network changes meet operational and security standards
Maintain clear, accurate documentation of firewall configurations and network security controls

What we need to know about you

Essential:

Strong hands-on experience operating and supporting enterprise firewall platforms (preferably Palo Alto) in complex environments
Proven background in network engineering, including routing, switching, and secure network design across Cisco & Aruba environments
Experience managing firewall policies, NAT, VPNs, and network segmentation in production environments
Practical experience with Network Access Control (NAC) solutions such as Aruba ClearPass (or Cisco ISE), including authentication and device profiling
Experience supporting secure remote access solutions, including VPN and SSE/SASE platforms (e.g. HPE SSE) in enterprise environments
Experience supporting multi-site environments, including remote access and site-to-site connectivity
Demonstrated ability to troubleshoot complex firewall, network, and remote access issues under operational pressure
Experience working in OT or industrial environments, or other high-availability, safety-critical networks
Experience managing and assuring third-party vendors, ensuring network and firewall changes are delivered to an appropriate standard
Strong operational discipline, including documentation, change control, and maintaining supportable configurations

Desirable:

Experience with Fortinet firewall platforms
Experience implementing or transitioning to modern network platforms or NAC solutions
Exposure to SSE/SASE architectures, including policy design and traffic steering
Experience designing or implementing network segmentation, particularly in OT or industrial environments
Knowledge of zero trust principles and modern approaches to network security
Experience with high availability firewall designs, including clustering and failover strategies
Familiarity with monitoring, logging, and traffic analysis tools for firewall and network environments
Scripting or automation experience (e.g. Python, APIs) to support network and firewall operations
