Job summary

Decipher Bureau in Canberra is seeking 3x Senior Network Security Engineers to join a high-performing secure networks team. You will own end-to-end delivery across LAN, WAN, SASE, SD-WAN, NGFW and datacentre projects, guiding design through handover.

The role offers a flexible hybrid work arrangement, client-site preference, and a clear path to senior leadership within a federal-focused security practice.

Qualifications

• 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).

Responsibilities

• 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.
