We are seeking a Senior Cyber Security Network Engineer to design, implement and maintain secure, resilient network infrastructure across complex enterprise environments. This role will lead the delivery of network security capabilities, protect critical systems and data, and provide expert guidance on emerging threats, vulnerabilities and defensive technologies. You will work closely with infrastructure, cloud, operations and risk teams to ensure security is embedded across network architecture, projects and day-to-day services.

Key responsibilities include developing and maintaining secure network designs, firewalls, intrusion prevention systems, secure web gateways, VPNs, network access controls and segmentation solutions. You will monitor and investigate security events, support incident response, conduct vulnerability assessments and recommend improvements based on threat intelligence and industry best practice. The role will also involve reviewing technical changes, contributing to security standards and policies, producing clear documentation, and leading complex troubleshooting activities. You may also provide technical leadership to engineers, support audits and compliance reviews, and contribute to continuous improvement initiatives.

Applicants should have substantial experience in cyber security and network engineering within large or technically complex environments. Strong knowledge of TCP/IP, routing and switching, DNS, proxy technologies, firewalls, network monitoring and security operations is essential. Experience with cloud networking, zero-trust principles, identity-aware access controls, automation and security information and event management platforms would be highly advantageous. Relevant professional certifications in networking or cyber security are desirable, alongside practical experience of risk management, incident handling and secure architecture. You will be an analytical and confident communicator, able to explain technical risks to both specialist and non-specialist audiences, manage competing priorities and make sound decisions in a fast-changing environment.
