The Cyber Architecture and Assurance team provides independent assurance over ASX’s cyber control environment, helping protect the integrity, availability and resilience of market-critical services.

The team works across Cyber Security, Technology and business stakeholders to establish assurance standards, govern testing activity, coordinate specialist external providers, drive accountability for remediation, and provide evidence over the effectiveness of controls across penetration testing, Red/Purple Team coordination, control validation and risk-based security assessment activities.

Coordinate ASX’s end-to-end penetration testing program, including annual planning, project-based testing, engagement governance, vendor delivery, reporting, closure and remediation follow-up.

• Coordinate Red Team and Purple Team activities, ensuring exercises are appropriately scoped, governed, safely executed and translated into actionable control improvement opportunities.

• Support budget allocation, forecasting and tracking for penetration testing and related assurance activities, including provider spend, planned testing demand and delivery risks.

• Hold technology, application, cloud, infrastructure, business and vendor teams accountable for triaging findings, agreeing remediation actions, tracking closure and escalating material risks where obligations are not being met.


• Evaluate, pilot and integrate AI-enabled or automated penetration testing capabilities into the broader cyber assurance and security testing strategy.


• Communicate testing outcomes, themes, delivery risks and risk insights clearly to technical teams, senior stakeholders and non-technical audiences.

• Background in information security, penetration testing principles, vulnerability assessment and risk-based security assurance.
• Exposure to the delivery lifecycle for security testing or assurance engagements, including planning, scope governance, readiness management, execution oversight, reporting or remediation follow-up.
• Experience working with external security vendors or penetration testing service providers, including delivery coordination, quality review or performance follow-up.
• Ability to translate project, system and control risk into clear testing objectives, rules of engagement, readiness expectations and remediation priorities.
• Exposure to penetration testing across complex technology environments, such as applications, APIs, infrastructure, cloud platforms and critical business systems.
• Ability to influence stakeholders and drive accountability across technology, project, application, infrastructure, cloud, business and vendor teams.
• Working knowledge of engagement governance, including roles and responsibilities, readiness criteria, escalation paths, reporting cadence and quality expectations.
• Working knowledge of contemporary security testing methodologies, common vulnerability classes and relevant cyber security frameworks or regulatory expectations.

• Hands-on penetration testing experience, noting ASX primarily uses a panel of specialised providers for delivery.
• Experience with Red Team or Purple Team exercises, including exercise planning, coordination, debriefs and translation of outcomes into control improvements.
• Experience with AI-driven, automated or continuous security testing tools, including safe adoption, governance and integration into assurance workflows.
