The Opportunity

Are you a senior network security specialist who enjoys getting hands-on with complex enterprise environments while also providing technical leadership?

We are looking for an experienced Principal Technical Specialist – Network Security / Firewalls to join a major enterprise cyber security uplift and firewall replacement program.

This is an exciting opportunity to play a key technical role across a large-scale environment, working with leading security technologies including Check Point, Palo Alto, Cisco and F5.

While the role involves providing senior technical direction, it is not a pure architecture position. You will remain hands-on, solving complex technical challenges, leading implementation activities and helping shape secure, reliable enterprise network environments.

What You'll Be Doing

You will have the opportunity to:

• Lead the end-to-end deployment, replacement, upgrade and configuration of Check Point firewalls.
• Provide specialist technical support across Palo Alto enterprise security solutions.
• Support, maintain and optimise firewall environments to ensure security, availability and performance.
• Integrate firewall solutions with Cisco routing and switching infrastructure.
• Work with F5 LTM, GTM and WAF technologies.
• Manage and optimise firewall rule bases using AlgoSec or comparable Network Security Policy Management tools.
• Monitor firewall health and performance using SolarWinds or similar platforms.
• Provide advanced troubleshooting, root-cause analysis and Level 3 technical support.
• Work collaboratively with project teams, operational teams, technology vendors, suppliers and systems integrators.
• Develop high-quality technical documentation, including solution designs, configuration artefacts, implementation plans, test plans, ICT change plans and rollback procedures.
• Provide technical leadership throughout firewall replacement and upgrade activities.
• Support the transition of newly implemented technologies into operational environments.
• Provide strategic technical advice on network security technologies, capabilities and emerging requirements.

About You

You will be a highly experienced network security professional who enjoys combining deep technical expertise with leadership and problem-solving.

Ideally, you will bring:

• Extensive hands-on experience with Check Point firewall technologies, including builds, replacements, upgrades, troubleshooting and policy optimisation.
• Strong practical experience with Palo Alto technologies in enterprise environments.
• Strong Cisco routing and switching knowledge, particularly in relation to firewall integration.
• Experience with F5 LTM, GTM and WAF.
• Experience with AlgoSec or an equivalent firewall policy/rule-base management platform.
• Experience using SolarWinds or comparable monitoring and reporting tools.
• Strong knowledge of security networking technologies, proxies and secure web gateways.
• Demonstrated experience providing advanced troubleshooting and third-level support within complex enterprise ICT environments.
• A solid understanding of cyber security standards, change management and service management practices.
• Experience working with ITIL processes, including incident, problem, change and configuration management.
• Strong technical documentation and solution-design capabilities.
• Excellent stakeholder engagement skills, with the ability to collaborate across technical teams, projects, operations and external technology partners.
• The ability to provide technical direction and mentoring to other technical specialists while continuing to work hands-on.
