Senior Network & Security Engineer

Senior Network & Security Engineer

We're partnering with one of Adelaide's leading independent Information and Communication Technology (ICT) solution providers to find a Senior Network & Security Engineer who's passionate about delivering high-quality network and security solutions across a genuinely diverse client base spanning Education, Utilities, Government, Defence and Corporate sectors. We're looking for someone with a genuine growth mindset: curious and committed to continuous learning, who thrives on taking ownership and sharing knowledge with those around them.

This is a technically rich role with a strong split between networking and security (leaning more heavily networking), where you'll take a proactive, design-led approach, assessing client requirements, producing technical designs, and delivering outcomes on an interesting range of projects.

What you'll be doing

• Designing and implementing enterprise network and security solutions, including SD-WAN (Fortinet), next-generation firewalls, routing, switching and wireless technologies.
• Translating high-level architectures into detailed technical designs and implementation plans.
• Supporting Solution Architects and Account Managers identify fit for purpose solutions for clients
• Acting as a senior technical escalation point for complex networking and security issues.
• Mentoring less experienced engineers and contributing to a culture of knowledge sharing.
• Participating in an on-call roster supporting critical customer environments.

What we're looking for

Must have:

• Strong experience operating at a senior (L4) level, or an L3 professional ready to step up into more design-focused work.
• Solid consulting or client-facing project experience.
• Hands-on expertise with SD-WAN/Fortinet and enterprise networking technologies.
• A proactive, growth-oriented mindset, comfortable owning technical design, not just delivery, and genuinely motivated to keep learning and developing.
• Strong communication skills and the ability to build trusted client relationships.

Nice to have:

• Experience with Palo Alto, Cisco Security, HPE Aruba, or Microsoft Azure networking and security.
• Exposure to Defence, Government or other highly regulated environments.

Why you'll love this role

• Join a collegiate and collaborative team of dedicated network/security engineers and Solutions Architects.
• Genuine variety of work across Education, Utilities, Government, Defence and Corporate clients.
• Supportive culture with regular team events.
• Fair, evenly distributed workload across the team.
• Flexible working.

Important to know

• Australian citizenship is preferred, given the nature of the client base.

If you're an experienced network and security professional who enjoys solving complex problems, taking ownership of technical design, and being part of a genuinely supportive team, we'd love to hear from you.
