Job description

Want to work for the best network security engineering team in the country? This is the kind of role that doesn't come around often.

About the Company & Culture:

We're partnering with one of Australia's leading cyber security consultancies. They're not a reseller chasing product quotas, they're a team of genuine technologists who get their hands dirty, know their tech inside out, and deliver real outcomes for clients.

The culture is technically deep, low-ego, and high-trust. Autonomy is the norm, seniority is earned through capability rather than tenure, and the team is proud of a reputation built on substance, not sales pitches.

The Role:

We're hiring a Senior Network Security Engineer to join a high-performing, Canberra-based secure networks team. You'll work across LAN, WiFi, WAN, SASE, SD-WAN, NGFW, and datacentre technologies, owning solutions end-to-end, from high-level design through to low-level design, implementation, and handover.

Location

Canberra - flexible hybrid working arrangements, with a preference on client site.

What You'll Be Doing

• Own the full delivery lifecycle: HLD, LLD, implementation, and handover, across complex network security solutions.
• Work hands-on across LAN, WAN, SASE, SD-WAN, NGFW, and datacentre environments.
• Partner with leading vendor technologies including Fortinet, Cisco, Palo Alto, Juniper, Aruba, and Cloudflare.
• Provide expert technical guidance to clients, translating business requirements into robust, practical solutions.
• Operate as an independent contributor on complex projects, while contributing to the team's broader technical knowledge base.

Experience Needed

• 5+ years of hands-on, senior-level networking experience.
• Integrator background strongly preferred - you've delivered across multiple clients and environments, not sat static in a single long-term customer contract.
• NV1 clearance preferred (or baseline considered).
• Strong in at least 1-2 of the core vendor technologies (Fortinet, Cisco, Palo Alto, Juniper, Aruba, Cloudflare).

Why Join?

• Career progression opportunities: a clear path to progress into a Principal role.
• Training and certification bonuses.
• Genuine WFH flexibility - the priority is time on client site, not desk-watching.
• Attractive Salary Package: up to $200k + Super, plus bonus potential.
