About the Role:
 
Our client is seeking a highly skilled Security Engineer with a strong focus on network security to support Project Aurora. This role is not a GRC position but is instead a hands-on technical role requiring expertise in securing, maintaining, and optimising network infrastructure in a classified environment.
As a Level 4/5 Security Engineer, you will be responsible for implementing, maintaining, and enhancing network security measures to protect critical systems. You will collaborate with security architects, network engineers, and system administrators to ensure compliance with security best practices and emerging threats.
 
Key Responsibilities:
 
· Design, implement, and manage network security solutions, including firewalls, intrusion detection/prevention systems (IDS/IPS), and VPNs.
· Conduct security assessments, vulnerability scanning, and penetration testing to identify risks and recommend mitigations.
· Monitor, analyse, and respond to security incidents affecting network infrastructure.
· Work closely with SOC and incident response teams to investigate and remediate security breaches.
· Support hardening of network devices, including routers, switches, and firewalls, in accordance with security baselines.
· Assist in the development and enforcement of security policies, procedures, and technical controls for secure network operations.
· Perform log analysis and network forensics to detect anomalies and potential security threats.
· Maintain documentation and compliance with security frameworks and government regulations.
· Stay up to date with emerging threats, vulnerabilities, and industry best practices in cybersecurity and network security.
 
Required Skills & Experience:
 
· Proven experience in network security engineering, preferably in classified or government environments.
· Hands-on expertise with firewalls (e.g., Palo Alto, Cisco ASA, Fortinet), IDS/IPS, SIEM solutions, and VPN technologies.
· Strong understanding of network protocols (TCP/IP, BGP, OSPF, etc.), encryption standards, and secure authentication mechanisms.
· Experience with penetration testing, vulnerability assessments, and remediation.
· Familiarity with Linux and Windows security hardening.
· Knowledge of Zero Trust Architecture (ZTA), Software-Defined Networking (SDN), and cloud security is a plus.
· Familiarity with Defence systems is highly desirable.
· Strong analytical and problem-solving skills with the ability to work independently and in a team.
· Excellent verbal and written communication skills to articulate security risks and technical concepts clearly.
 
Qualifications & Certifications (Desirable):
 
· Industry certifications such as CISSP, CCNP Security, GIAC, CEH, or equivalent are highly desirable.
· Bachelor's degree in Cybersecurity, Computer Science, Information Technology, or related field (or equivalent experience).
