We are seeking a Network Security Specialist to protect and strengthen a complex IT environment. You will be responsible for monitoring, managing and improving network security controls across corporate infrastructure, cloud services and remote access solutions. Working closely with infrastructure, service delivery and risk teams, you will help identify vulnerabilities, respond to incidents and ensure that systems remain resilient against evolving threats.

Your duties will include configuring and maintaining firewalls, intrusion prevention systems, secure web gateways, VPNs and network access controls. You will investigate alerts and suspected breaches, support incident response activities, analyse network traffic and produce clear technical reports. You will also conduct vulnerability assessments, contribute to penetration testing programmes, review security logs and recommend practical improvements to reduce risk. The role will involve developing and maintaining security standards, procedures and technical documentation, as well as supporting audits and compliance requirements.

Applicants should have proven experience in network security, infrastructure protection or a closely related technical discipline, with a strong understanding of TCP/IP, routing, switching, DNS, DHCP and common network protocols. Experience with firewall administration, SIEM platforms, endpoint protection, vulnerability management and cloud security is highly desirable. Relevant certifications such as CompTIA Security+, Cisco Certified CyberOps, CCNP Security, CISSP or equivalent experience would be advantageous. You should be confident analysing complex issues, prioritising competing demands and communicating technical information clearly to both specialist and non-specialist audiences. A methodical approach, sound judgement, curiosity and a commitment to continuous learning are essential. The successful candidate will be expected to participate in an out-of-hours incident response rota when required.
