Support and maintain network infrastructure, including firewalls, switches, VPNs, and wireless systems (primarily Cisco-based)
Own and drive security best practices, including system hardening, patching, vulnerability remediation, and endpoint protection
Monitor and respond to security events, including log analysis and threat identification, with awareness of modern attack vectors (including AI-enabled threats)
Contribute to the design and implementation of secure infrastructure solutions across both BAU and project work
Collaborate closely with infrastructure and security teams to deliver enhancements and strategic initiatives
Create and maintain clear documentation, including SOPs, architecture diagrams, and runbooks
Participate in an on-call rotation to support critical systems outside business hours

Requirements

Minimum 5+ years’ experience in infrastructure, networking, and security roles
Strong hands-on experience with Windows Server and Linux (Red Hat/CentOS)
Solid networking knowledge, including TCP/IP, VLANs, VPNs, DNS, DHCP, with practical experience in Cisco environments
Demonstrated experience implementing and supporting security controls, including:
Patch management and system hardening
Endpoint protection and monitoring
Identity and access management
Good understanding of cyber security principles, including modern threat landscapes and evolving risks (e.g. automation and AI-driven attack vectors)
Experience with virtualisation (VMware) and enterprise storage (SAN/NAS)
Scripting or automation experience (e.g. PowerShell, Bash) is advantageous
Experience in financial services or regulated environments is preferred
Strong troubleshooting skills with a structured and analytical approach
Able to balance BAU responsibilities with project delivery effectively
A thoughtful and forward-looking mindset, with the ability to identify risks and propose improvements
Clear and confident communicator, able to engage with both technical and non-technical stakeholders
Self-motivated, accountable, and willing to take ownership of issues end-to-end
Collaborative and adaptable, with a practical and solutions-focused approach
