Company Overview

You'll be working within the Australian Signals Directorate (ASD), a key part of Australia's national security capability.

ASD sits at the centre of signals intelligence, cyber security, and offensive cyber operations. The work here is mission-critical, high-trust, and directly tied to protecting Australia from global threats.

The Role

This is hands-on infrastructure engineering inside a highly secure, complex ICT environment.

What this really means is you'll be keeping critical networks running, resilient, and secure - not just maintaining systems, but actively improving how they perform under real operational pressure.

These roles sit at an APS6-equivalent level and involve shift work in environments where uptime and performance genuinely matter.

What You'll Do

• Support and maintain large-scale ICT infrastructure environments
• Work across Cisco and Juniper networking platforms, including cryptographic devices
• Monitor performance and reliability using tools like SolarWinds, Cisco Transport Controller, and Splunk
• Manage incidents, problems, and changes through ITSM platforms
• Perform system configuration, backups, and recovery operations
• Identify operational issues and contribute to resolution
• Document system processes, enhancements, and procedures
• Contribute to disaster recovery planning and testing

What You'll Bring

Must-have:

• Experience administering Cisco and/or Juniper network environments
• Strong infrastructure background across network and core ICT systems
• Experience monitoring and analysing network performance
• Solid troubleshooting capability in live operational environments
• Experience working with ITSM tools and incident management

Nice to have:

• Exposure to cryptographic or secure network environments
• Automation or scripting experience
• Experience in Defence or national security environments

Technical Capability (aligned to SFIA)

• Availability Management (Level 4): Managing system reliability, performance targets, and disaster recovery
• IT Infrastructure (Level 4): Implementing and maintaining infrastructure, automation, and performance monitoring
• Problem Management (Level 3): Investigating and resolving system issues
• Systems Installation (Level 4): Managing complex installs, upgrades, and handovers

Qualifications

• Relevant ICT qualifications or equivalent experience
• Must complete ASD Organisational Suitability Assessment (OSA) prior to commencement

Contract Details

• Potential Start: 1 September 2026
• Initial Term: 12 months
• Extensions: 2 x 12 months

Why Join

• Work on some of Australia's most sensitive and critical technology environments
• Be part of a mission that directly impacts national security
• Exposure to complex, high-security infrastructure at scale
• Strong pathway for long-term contract extensions

Important Notes

• Current TSPV clearance is required
• Roles involve shift work
• Work is fully onsite due to operational requirements
• Employer must hold DISP membership
• Candidates will be allocated based on operational need after suitability assessment
