• Provide detailed, specialist technical advice, including strategic advice to senior executives
• Contribute to the development of recovery routines and contingency procedures
• Contribute to alternative network architectures, networking topologies and design options
• Identify risks arising from potential technical solution architectures, designing alternate solutions or countermeasures
• Investigate suspected attacks and support security incident management
• Provide guidance on the application and operation of elementary physical, procedural and technical security controls

Required

• Ability to complete ASD's Organisation Suitability Assessment (OSA) prior to commencement
• APS6-equivalent experience level
• Demonstrated experience in the design and deployment of network infrastructure, including Cisco Data Centre technologies (ACI, Routers, Nexus switches) and routing protocols (BGP, OSPF, EIGRP)
• Demonstrated experience with or detailed understanding of Palo Alto firewalls and IPS solutions
• Technical proficiency in designing services using F5/Blue Coat/Citrix NetScaler/Broadcom SWG Layer 4-7 switching, load balancing and proxy systems
