We are seeking a forward-thinking and highly technical Security Architect to lead the secure design and implementation of our next-generation platforms. As the technology landscape rapidly evolves, this role is critical in ensuring our adoption of artificial intelligence, cloud infrastructure, and modern developer workflows remains both secure and agile. You will act as a key business enabler, partnering closely with engineering teams to embed security seamlessly into the development lifecycle while managing emerging risks in AI and multi-agent architectures.

At Macquarie, our advantage is bringing together diverse people and empowering them to shape all kinds of possibilities. We are a global financial services group operating in 31 markets and with 56 years of unbroken profitability. You'll be part of a friendly and supportive team where everyone - no matter what role - contributes ideas and drives outcomes.

What role will you play?

In this role, you will be responsible for architecting secure AI systems by leading threat modelling initiatives and designing robust security controls for modern agentic and Agent-to-Agent (A2A) architectures. You will embed DevSecOps practices by designing, implementing, and overseeing critical security controls across CI/CD pipelines to ensure secure software supply chains and developer workflows. Additionally, you will secure cloud and container infrastructure by defining and enforcing security architecture patterns across cloud environments such as AWS, GCP, and Azure, with a strong focus on container runtime security. Finally, you will act as a trusted advisor to technical stakeholders, translating complex security risks into practical, balanced strategies that support, rather than hinder, the pace of technology adoption.

What you offer

• Deep understanding of AI concepts and AI-based threat modelling.
• Well-versed in Agentic architectures, multi-agent frameworks, and Agent-to-Agent (A2A) architectures and their related security patterns.
• Familiarity with agent development platforms such as LangGraph and ADK.
• Comprehensive understanding of critical pipeline controls and vulnerability management within pipeline steps.
• Working knowledge of Git-based platforms (e.g., GitHub Enterprise, GitLab).
• Proven experience in software supply chain security and securing developer tooling and workflows.
• Working knowledge of cloud services and their native security controls across AWS, GCP, and/or Azure.
• Specific focus and deep technical expertise in securing container runtimes.
• Great communication and capable of effectively influencing technical stakeholders and engineering teams.
• Strong capability in risk management.
• Adept at balancing rigorous security requirements with the velocity of technology adoption to act as a true business enabler.
