Senior Systems Integration Architect in Canberra

Lead systems architecture and integration across complex Defence capabilities, enabling interoperability across the Land domain. Join our Downer Professional Services team and play a key role in delivering complex defence and national security projects that safeguard Australia's future. Downer Professional Services comprises three business units: our Technical, Advisory, and Capability consulting practice, and Team Downer, which partners with CASG and NSSG as a major service provider to Defence. Together, we are a multi-disciplinary advisory and delivery partner of choice for clients across Defence and National Security.

This role offers a broad scope, with key responsibilities including:

• Identify, define, design and validate digital integration requirements for Land programs and projects.
• Assess and support integration approaches from pre-Gate 0 through to Gate 2, and address post-Gate 2 digital integration risks and issues.
• Support the integration of Land Mobility and Support Program platforms, including C4I fit-out and interoperability with Land C4ISREW capabilities.
• Apply systems architecture, systems engineering and system-of-systems integration expertise to develop and operationalise the Land Integration Framework - Digital.
• Engage and influence stakeholders across Army, Land Capability Division, VCDF, CASG and other Defence domains to support evidence-based integration decisions.

What You’ll Bring:

• Demonstrated advanced-practitioner experience in systems architecture, systems engineering and digital integration within complex ICT or Defence environments.
• Strong knowledge of system-of-systems design, interoperability, interface definition and technical assurance.
• Experience analysing C4I or C4ISR systems, capabilities and network integration requirements.
• Ability to develop clear technical advice, integration artefacts and recommendations for senior stakeholders, programs and projects.
• Highly developed stakeholder engagement skills, with the ability to collaborate across multidisciplinary teams and influence complex capability outcomes.

Due to the nature of the work, you are required to currently hold and maintain an AGSVA Security clearance as required by the Commonwealth. In some instances, compliance with International Traffic in Arms Regulations (ITAR) requirements may also be an inherent requirement. More than anything, you’ll bring a strong work ethic, a positive attitude, and a commitment to delivering high-quality outcomes for our clients.
