Network Security Engineer
We are seeking a skilled Network Security Engineer to design, implement and maintain secure, resilient network infrastructure across a complex technology environment. You will be responsible for protecting systems, applications and data from evolving cyber threats while supporting the availability and performance of critical services. This role will work closely with infrastructure, cloud, development and operations teams to embed security into network architecture and day-to-day delivery.
Key responsibilities include configuring and managing firewalls, intrusion prevention systems, secure gateways, VPNs, network access controls and security monitoring tools. You will investigate alerts and incidents, perform root-cause analysis, and coordinate appropriate containment, remediation and recovery activities. The role will also involve conducting vulnerability assessments, reviewing network designs, maintaining security rules and policies, and supporting audits and compliance requirements. You will contribute to threat modelling, security improvements, technical documentation and the development of repeatable operational procedures.
The successful candidate will have proven experience in network security engineering, with strong knowledge of TCP/IP, routing, switching, DNS, HTTP/S, segmentation and common network attack techniques. Practical experience with technologies such as next-generation firewalls, IDS/IPS, SIEM platforms, endpoint security, cloud networking and identity-based access controls is highly desirable. Relevant certifications or equivalent hands-on experience in networking and cyber security will be valued. You should be analytical, methodical and confident working through complex incidents, with the ability to communicate technical risks clearly to both technical and non-technical stakeholders. A proactive approach to continuous improvement, strong documentation skills and a commitment to secure-by-design principles are essential.
