Using cloud, DevSecOps, automation, cybersecurity and AI, DDM helps modernise complex environments and strengthen Defence's operational capability.

The Opportunity

As an Enterprise Cloud and Platform Architect, you will shape the architecture, governance and evolution of enterprise hosting, cloud, virtualisation, identity and platform services supporting Defence and national security customers. Working across complex hybrid environments, you will connect technology strategy with mission outcomes and help guide significant platform modernisation initiatives.

• Design and govern hybrid cloud environments spanning AWS, Microsoft Azure and other cloud platforms, including landing zones, migration strategies, integration patterns and operating models.
• Guide the modernisation of enterprise hosting and virtualisation services, including container platforms, software-defined infrastructure and the transition from legacy technologies.
• Partner with customer stakeholders, engineering and service delivery teams, security specialists, technology vendors and senior leaders to facilitate architecture workshops, technical reviews, governance and assurance activities.

You are comfortable working across architecture, engineering, security and service delivery functions to balance modernisation opportunities with operational and accreditation requirements.

Essential:

• At least seven years' experience in cloud and platform engineering and/or architecture.
• Experience designing enterprise hybrid cloud environments using AWS and/or Microsoft Azure, including cloud migration, transformation, governance, security and operating models.
• Experience across enterprise data centre and hosting environments, including VMware vSphere, virtualisation, workload migration and storage, compute and networking architectures.
• Capability in developing technology roadmaps, architecture artefacts, design patterns and reference architectures.
• Experience contributing to architecture governance, design reviews and technical assurance activities.
• Ability to engage senior customer stakeholders, technology partners and multidisciplinary delivery teams, and to communicate technical concepts clearly to executive audiences.
• A bachelor's degree or relevant qualification in Computer Science, Information Technology, Engineering or a related discipline.

Advantageous:

• Experience with Kubernetes, Nutanix, container platforms or software-defined infrastructure.
• Knowledge of DevSecOps, automation and infrastructure-as-code practices.
