We are seeking a Junior Network Security Support Engineer to assist with the operation, maintenance and protection of network infrastructure across a dynamic technical environment. This is an excellent opportunity for an early-career professional who is keen to develop practical experience in network security, monitoring and incident response while working alongside experienced infrastructure and cybersecurity specialists.

Key responsibilities will include monitoring network traffic, security alerts and system events; investigating and escalating suspicious activity; supporting the administration of firewalls, intrusion detection and prevention systems, secure gateways and access controls; and assisting with vulnerability assessments, patching and remediation activities. You will help maintain accurate technical documentation, contribute to security reporting and asset inventories, and support the implementation of network security policies and procedures. The role will also involve responding to service requests and incidents, troubleshooting connectivity and security issues, and collaborating with internal technical teams to resolve problems efficiently and securely.

Applicants should have a foundational understanding of networking concepts, including TCP/IP, DNS, DHCP, routing, switching, VPNs and common network protocols. Familiarity with firewalls, endpoint protection, security information and event management tools, or vulnerability scanning technologies is desirable. Relevant qualifications in networking, cybersecurity, information technology or a related discipline are advantageous, as are certifications such as CompTIA Network+, Security+ or equivalent. You should demonstrate strong analytical and problem-solving skills, careful attention to detail and a willingness to learn. Clear communication, effective teamwork and the ability to follow documented processes are essential. This position may require participation in an out-of-hours support rota and adherence to strict security, confidentiality and data protection requirements.
