This is a hands-on infrastructure engineering opportunity with a strong focus on Linux administration, system hardening, configuration management, automation, infrastructure lifecycle support and secure ICT environments.

The requirement is for 4 Infrastructure Engineers at APS6-equivalent level, with an initial 12-month engagement and potential for 2 x 12-month extensions. Candidates must hold a current TSPV security clearance at the time of submission.

About the Role The successful engineers will support the implementation, management, maintenance and eventual retirement of infrastructure used to deliver secure digital services.

The environment may include physical, virtual, networking and cloud infrastructure, but the strongest sourcing focus for this opportunity is candidates with solid Linux infrastructure engineering and hardening experience.

This is a practical engineering role across the broader system development and operational lifecycle, with responsibility for:

- Linux systems administration
- Secure system configuration
- Infrastructure hardening
- Infrastructure automation
- Configuration management
- Systems installation and maintenance
- Infrastructure testing
- Technical troubleshooting
- Availability and recovery
- Infrastructure design
- Operational support

Key Responsibilities

You may be responsible for:

- Administering and maintaining Linux-based systems
- Performing Linux system hardening and secure configuration
- Installing, configuring, maintaining and decommissioning infrastructure
- Supporting physical, virtual, network and cloud infrastructure
- Developing and maintaining automation and administration scripts
- Automating infrastructure provisioning, testing and deployment
- Supporting configuration management and controlled infrastructure changes
- Planning and implementing infrastructure maintenance and updates
- Conducting technical testing and resolving system faults
- Monitoring infrastructure availability, reliability and performance
- Supporting disaster-recovery arrangements and recovery testing
- Contributing to infrastructure and systems design
- Supporting integration builds and technical verification activities
- Reviewing test plans and procedures against technical requirements
- Maintaining operational procedures and technical documentation
- Resolving infrastructure issues during capability development
- Providing recommendations for infrastructure improvement
- Engaging with technical stakeholders and delivery teams as required.

Linux Engineering Focus

Linux is a key part of this requirement.

We are particularly interested in engineers with practical experience across:

- Linux systems administration
- Linux configuration
- Linux system hardening
- Secure Linux environments
- Patch and update management
- Linux troubleshooting
- Operational maintenance
- Configuration compliance
- Infrastructure security controls
- Linux-based service availability
- Automation supporting Linux environments

Candidates should be able to demonstrate what they personally configured, hardened, automated, maintained or resolved in Linux environments.





Infrastructure Automation & Configuration Management The role also requires demonstrated experience in configuration management and automation.

Relevant experience may include

- Infrastructure automation
- Automated provisioning
- Automated testing
- Automated deployment
- Configuration management
- Infrastructure scripting
- Repeatable build processes
- Controlled infrastructure changes
- Environment standardisation
- Operational automation
- Technical configuration documentation

The strongest candidates will be able to explain how automation improved consistency, reliability, deployment speed or operational support.

Systems Installation & Lifecycle Support The role covers the full lifecycle of infrastructure components.

Relevant experience includes

- Installation
- Configuration
- Maintenance
- Upgrade
- Testing
- Troubleshooting
- Operational handover
- Decommissioning / removal

Experience undertaking or supporting complex installations within secure enterprise environments would be particularly relevant.

Systems Design

Candidates should also be comfortable contributing to systems and infrastructure design.

Relevant capability includes

- Designing system components against agreed architectures
- Applying technical standards and design patterns
- Evaluating design options and trade-offs
- Addressing functional and non-functional requirements
- Producing detailed technical specifications
- Reviewing and improving designs

- Serviceability
- Performance targets
- Disaster recovery
- Recovery procedures
- Recovery testing
- Service continuity
- Infrastructure resilience

Engineers should understand how to maintain infrastructure so services continue to meet required performance and availability expectations.

Scripting Capability

This is not a software-development role, but practical scripting capability is expected.

Relevant experience includes

- Writing infrastructure scripts
- Testing and verifying scripts
- Maintaining scripts
- Documenting scripts
- Refactoring simple automation
- Using scripting to support provisioning, deployment, testing or administration

The most relevant candidates will use scripting as a practical infrastructure engineering and automation tool.

Essential SFIA Criteria

Each candidate will be required to address five essential SFIA criteria as part of the formal submission:

- Availability Management – Level 4
- IT Infrastructure – Level 4
- Programming / Software Development – Level 2
- Systems Design – Level 4
- Systems Installation & Removal – Level 4

Each criterion response is limited to 3,000 characters.

Azooa can work with shortlisted candidates to help position their experience clearly against these requirements.

Core Experience We’re Looking For

Solid candidates should demonstrate experience across several of the following:

- Linux administration




- Linux system hardening
- Infrastructure engineering
- Configuration management
- Infrastructure automation
- Scripting
- Systems installation
- Systems maintenance
- Infrastructure troubleshooting
- Secure enterprise environments
- Availability management
- Disaster recovery
- Infrastructure design
- Integration testing
- Verification and validation
- Physical infrastructure
- Virtual infrastructure
- Network infrastructure
- Cloud infrastructure

You do not need experience in every area listed.

The strongest candidates will combine hands-on Linux capability with infrastructure engineering, automation and secure-environment experience.

Security Clearance

This is the key eligibility requirement.

? Candidates must hold a current TSPV security clearance at the time of submission.

The RFQ specifically clarifies that although the portal may display an option referring to the ability to obtain Positive Vetting, TSPV must already be current at submission for a candidate to be eligible.

Suitable candidates will also need to complete an Organisation Suitability Assessment (OSA) before commencement.

Location & Working Arrangements

- ? Canberra, ACT
- ? Onsite
- ⏰ Up to 40 hours per week

Working arrangements will depend on the assigned work area and operational need.

Due to the nature of the secure environment, candidates should be comfortable working onsite in Canberra, as not all work areas can accommodate working from home.

Engagement Details

- Role: Senior Linux Infrastructure Engineer
