About the Team

You’ll join a team where people work with integrity, inclusion, innovation, agility, collaboration and commitment. In practice, that means sharing ownership, solving complex problems together and staying connected to the customer context, the purpose behind the work and how each role contributes to meaningful outcomes.

We deliver prime systems integration projects which build, develop and support military solutions for Defence. The team focuses on leveraging our local engineering, our services expertise, and global products to bring new capabilities to the Australian Defence Force.

The Opportunity

The Air Component Command and Control Capability System (AC-C2CS) is a mission-critical suite of software applications that enables the Australian Defence Force (ADF) to effectively plan, prepare, execute, manage, and report on aviation operations.

• Support virtualisation platforms and migration activities, including Hyper-V administration and VMware to Hyper-V transition projects.
• Provide infrastructure engineering expertise to projects and operational teams, contributing to solution development, planning activities and the successful delivery of technical outcomes across the AC-C2CS program.

• Experience in infrastructure engineering, systems administration or platform support roles.
• Capability in deploying, configuring and maintaining virtualisation technologies, including Hyper-V.

• Ability to work effectively within highly regulated, secure or mission-critical environments.
• Current NV2 Security Clearance or the ability to meet program requirements where applicable.
• Ability to satisfy ITAR requirements.

Advantageous

• Experience with VMware administration and virtualisation migration activities.
• Experience delivering infrastructure projects across geographically dispersed or multi-site environments.
