Network Security Support Engineer
We are seeking a Network Security Support Engineer to provide technical support, monitoring, and maintenance for secure network environments. The successful candidate will help protect infrastructure, systems, and users by investigating security alerts, resolving network-related incidents, and supporting the implementation of effective security controls. This role will work closely with infrastructure, service desk, and cybersecurity teams to ensure that issues are identified and addressed promptly while maintaining a high standard of service.
Key responsibilities include monitoring firewalls, intrusion prevention systems, VPNs, secure gateways, and network traffic for potential threats or operational issues. You will troubleshoot connectivity and security incidents, analyse logs and alerts, escalate complex cases where necessary, and maintain accurate incident and change records. The role will also involve supporting firewall rule reviews, access control updates, vulnerability remediation, patching activities, security testing, and the maintenance of technical documentation and operating procedures. You may contribute to network upgrades, audits, disaster recovery exercises, and the continuous improvement of monitoring and support processes.
Applicants should have practical experience in network or security operations and a sound understanding of TCP/IP, DNS, DHCP, routing, switching, VPN technologies, firewalls, and common network security principles. Experience with security monitoring or SIEM platforms, authentication technologies, endpoint protection, and incident management tools would be advantageous. Strong analytical and troubleshooting skills are essential, along with the ability to communicate clearly with both technical and non-technical colleagues. Relevant certifications or training in networking and cybersecurity are desirable. You should be organised, customer-focused, able to manage competing priorities, and willing to participate in an out-of-hours support rota when required.
