Security Platform Lead

About the Team

Our Enterprise Platforms team contributes to the delivery of our strategic goals by ensuring we have a modern and efficient workplace that keeps our people connected, and by delivering evergreen technology infrastructure platforms and services that are scalable, secure and fit for purpose.

About The Role

As part of the Enterprise Platforms team, you will be accountable for the operational performance, stability and prioritisation of our security infrastructure platforms, including firewalls, load balancers, TLS termination, certificates and associated controls. You will provide clear daily direction to our managed service provider (MSP), own security infrastructure change and incident outcomes, and ensure controls remain reliable, auditable and aligned to service availability. You will also support cyber incidents through initial review, infrastructure containment execution and coordination of Security Engineers and MSP Engineers.

Key Responsibilities

• End-to-end ownership of:
• Firewalls
• Load balancers
• Proxies
• External certificates, domains and DNS
• Setting daily priorities for all security-related business-as-usual work
• Providing leadership, support and a technical escalation point for security infrastructure, which may extend outside business hours
• Owning risk management plans and processes, and successfully implementing and operating them across teams
• Acting as the primary contact for security infrastructure incidents, changes and outcomes
• Assessing risk and service impact for proposed and emergency changes
• Representing security changes and improvements at relevant meetings and forums
• Providing ownership and guidance of security infrastructure policies, procedures, design and configurations
• Leading security infrastructure lifecycle planning, including end-of-life and end-of-support remediation
• Overseeing vulnerability and patch management
• Partnering with Architecture and project teams on security design and effort estimation
• Providing insight and guidance on new and emerging security technologies
• Upholding your duty of care by embedding WHS in daily activities, adhering to the Bank's policies and procedures, and actively promoting a physically and psychologically safe workplace
  

You bring valued experience as a Security Engineer and are ready to provide clear platform leadership across multiple security disciplines. Under your leadership, security-related changes are controlled and predictable, certificate renewals occur without urgency, and cyber-related actions are appropriately triaged and coordinated. You ensure audit evidence is readily available, infrastructure security practices and processes are well documented, and MSP delivery is consistent and low-risk.
