Develop secure segmentation strategies aligned to Zero Trust principles.
Use automation tools such as Python, Ansible, and REST APIs.
Design and optimise application delivery using Citrix NetScaler, including load balancing, WAF, content switching, and traffic steering.
Support high-availability and disaster-recovery planning for critical services.
Collaborate with application and infrastructure teams to ensure performance, resilience, and secure traffic flows.
Provide third-line technical support and mentor second-line staff.
Monitor performance and support continuous improvement across key network services.

Experience in security architecture design and implementation
Excellent understanding of TCP/IP, Cisco firewalls, ACI networks, LAN, WAN, and VPN systems
Familiarity with Identity & Access Management (I&AM) and cyber security
Knowledge of threat management and vulnerability assessment
Good working knowledge of ITIL, change management, and continual improvement
Strong communication and documentation skills

What’s on offer

12-month contract
Senior-level technical ownership
A high-impact security and network architecture remit
The chance to work on critical infrastructure with real scale and visibility
