Patch & Vulnerability Management: Oversee the technical operation of the enterprise vulnerability scanning program, working with IT Operations to prioritize and track remediation of system and software vulnerabilities. C. Network Security Engineering & Infrastructure Firewall Management: Design, implement, and maintain complex rule sets and policies on Next-Generation Firewall (NGFW) platforms, managing network segmentation, site-to-site VPNs, and secure remote access. Intrusion Detection/Prevention (NIPS): Configure and tune Network Intrusion Prevention Systems (NIPS) and Intrusion Detection Systems (IDS) to actively block and alert on malicious network traffic and policy breaches. Security Tool Implementation: Lead the research, deployment, and operationalisation of new network and cloud security tooling, ensuring full integration with our Security Information and Event Management (SIEM) system. Architecture Review: Conduct security reviews of network diagrams and proposed infrastructure changes to ensure secure deployment prior to production release. 2. Required Skills and Experience Professional Experience: Proven experience (typically 4 years) in a security engineering role, with demonstrable expertise across Application, Systems, and Network security domains and associated technology controls. Industry Knowledge: Previous experience working within the UK financial services, banking, or highly regulated industry. Compliance: Excellent working knowledge of UK and EU regulatory requirements, and Exposure to ‘Cyber Essentials plus’. Technical Stack: Expertise in managing and troubleshooting enterprise-grade firewalls (e.g., Palo Alto, Fortinet, Cisco ASA).

Reporting: Ability to communicate complex technical security risks and compliance gaps effectively to the CISO. 3. Desirable Qualifications Relevant industry certifications (e.g., CISSP, CISM, SSCP). Cloud-specific security certification (e.g., AWS Certified Security – Specialty, Microsoft Azure Security Engineer Associate). Certifications related to specific technologies, such as PCNSE, CCNP Security, or GIAC. Experience with Infrastructure as Code (IaC) security scanning tools (e.g., Checkov, Terrascan). 4. Work Arrangement and Benefits Hybrid Working: This role operates under a flexible hybrid model, requiring attendance at our Manchester or Liverpool, UK office for essential collaboration meetings (e.g., 2-3 days per week) with the remainder of the time working remotely.
