If you’re a senior technical leader with deep experience in secure platforms, hybrid cloud, and critical national systems, this is an opportunity to join one of the most impactful digital transformation programs in Australia’s national security landscape.

You will sit at the strategic intersection of platform architecture, secure integration, risk, and enterprise uplift, influencing the design and assurance of highly classified platforms relied upon by government and national-level partners.

This role is ideal for someone who thrives in high-tempo environments, provides calm technical authority, and delivers clarity to senior executives grappling with complex technical challenges.

Unlike standard architecture roles, this position gives you the chance to:

• Influence enterprise-level platform strategy across some of the most secure environments in the country.
• Shape how national security organisations design, secure, and integrate hybrid and multi-cloud ecosystems.
• Work directly with senior executives, contributing to decisions that have national-level consequences.
• Lead technical governance, design assurance, and solution integration across complex, high-trust digital platforms.

This is a role for someone who wants their work to truly matter.

• Deliver authoritative technical advice across secure networks, cross-domain gateways, and multi-cloud/hybrid platforms (SaaS, PaaS, IaaS).
• Lead technical engagement across national security stakeholders, ensuring clarity of requirements, robust design governance, and timely solution assurance.
• Translate complex architectural and integration challenges into actionable, executive-ready insights for senior decision-makers.
• Oversee and assure the design of secure, scalable, maintainable solutions aligned with security classifications, compliance frameworks, and the enterprise ICT strategy.
• Provide senior technical leadership across multi-disciplinary delivery teams, ensuring interoperability across cloud, on-prem, and cross-domain components.
• Embed architectural principles that uplift resilience, interoperability, and alignment across multiple high-security platforms.
• Mentor emerging technical leaders and support capability uplift through structured knowledge sharing.
