Senior Network Security Engineers

About the Company & Culture:
We're partnering with one of Australia's leading cyber security consultancies, widely regarded by clients and industry peers as home to the best networking team in the country. 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. With a strong federal government pipeline building, this is a genuine growth story with real career runway.
  
The Role:
We're hiring for 3x Senior Network Security Engineers 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 - very flexible hybrid working arrangements, with a preference for working 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.
• Stay current with the latest platform releases and vendor developments - this is a team that is genuinely passionate about all things networking and firewalls.

  
Experience Needed:

• 3-4+ years of hands-on, mid to 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.
• A true technologist: someone who knows the latest firewall release, not a corporate operator.
• Federal market experience or strong interest in the space.
• NV1 clearance preferred (or baseline considered).
• Comfortable owning projects independently - this is not a service desk or early-career network role.
• 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.
• Culture Awards recognising genuine excellence!
• A vibrant, social, tight-knit Canberra office community.
• Genuine WFH flexibility - the priority is time on client site, not desk-watching.
• Attractive Salary Package: up to $200k + Super, plus bonus potential.
