- Support, maintain and optimise firewall environments to ensure security, availability and performance.
n
- Integrate firewall solutions with Cisco routing and switching infrastructure.
n
- Work with F5 LTM, GTM and WAF technologies.
n
- Manage and optimise firewall rule bases using AlgoSec or comparable Network Security Policy Management tools.
n
- Monitor firewall health and performance using SolarWinds or similar platforms.
n
- Provide advanced troubleshooting, root-cause analysis and Level 3 technical support.
n
- Work collaboratively with project teams, operational teams, technology vendors, suppliers and systems integrators.
n




- Develop high-quality technical documentation, including solution designs, configuration artefacts, implementation plans, test plans, ICT change plans and rollback procedures.
n
- Provide technical leadership throughout firewall replacement and upgrade activities.
n
- Support the transition of newly implemented technologies into operational environments.
n
- Provide strategic technical advice on network security technologies, capabilities and emerging requirements.

n

n
- Extensive hands-on experience with Check Point firewall technologies, including builds, replacements, upgrades, troubleshooting and policy optimisation.
n
- Robust practical experience with Palo Alto technologies in enterprise environments.
n
- Strong Cisco routing and switching knowledge, particularly in relation to firewall integration.
n
- Experience with F5 LTM, GTM and WAF.
n
- Experience with AlgoSec or an equivalent firewall policy/rule-base management platform.
n
- Experience using SolarWinds or comparable monitoring and reporting tools.

- Experience working with ITIL processes, including incident, problem, change and configuration management.
n
- Strong technical documentation and solution-design capabilities.
