Your New Role And Responsibilities

Are you passionate about defending digital environments and making a real impact? Join a small, agile cyber security team where your work directly contributes to protecting users, systems, and services in a dynamic and mission-critical setting.

Working in the Cyber security team, you'll play a hands-on role across a broad range of security functions—from threat detection and incident response to patch assurance, endpoint and mobile device protection, and governance. You'll collaborate closely with experienced IT Security professionals and report to the Technical Cyber Manager, gaining exposure to diverse technologies and real-world challenges.

This is a unique opportunity to show off and continue to grow your skills across multiple domains, contribute to meaningful outcomes, and be part of a team that values innovation, responsiveness, and continuous improvement.

Key Responsibilities

• Coordinate vulnerability and patch management activities, including scheduling scans, prioritising remediation, validating patch deployment, and tracking outcomes to ensure timely resolution of known risks.
• Manage active security monitoring and incident response, performing log analysis, alert triage, and threat detection, while contributing to incident handling workflows and maintaining response readiness.
• Support identity and access security controls, including enforcement of passkey-based multi-factor authentication, privileged account management, password rotation, and access reviews, while maintaining platform health and audit readiness.
• Contribute to cyber threat intelligence and governance, by analysing threat feeds, correlating indicators with internal data, configuring CASB and DLP policies, and conducting system reviews to assess compliance and recommend remediation.

Qualifications & Experience

• Demonstrated experience in a cyber security or IT security role, with exposure to a broad range of operational security functions across endpoint, cloud, and access management.
• Proficiency with security technologies including SIEM platforms, endpoint detection and response (EDR) tools, vulnerability scanners, and patch management systems.
• Working knowledge of cyber security frameworks and standards such as the Information Security Manual (ISM), Protective Security Policy Framework (PSPF), and the Essential Eight Maturity Model, with practical experience applying them in operational contexts.
• Experience supporting governance, risk, and compliance activities including risk assessments, and preparation of audit-ready documentation.
• Proven communication and collaboration skills, with the ability to engage effectively across technical teams and articulate security risks and recommendations to management and teams. And ability to engage with customers and support incident response activities through IT Service Management (ITSM) tools.

This role does require the successful applicant to be an Australian Citizen and hold or be able to obtain a NV1 level security clearance.
