Job Title:

Cyber Threat Defence Team Lead

Overview:

Medibank seeks a seasoned cyber defence leader to head our high-performing team of security specialists. This role is critical in designing, delivering, and continuously improving scalable, intelligence-driven threat defence strategies that support our strategic and regulatory objectives.

Responsibilities:

  1. Lead the development and implementation of advanced threat detection technologies, incident response protocols, and security automation.
  2. Oversee threat intelligence, vulnerability management, behavioural analytics, malware defence, and SOC operations.
  3. Ensure rapid and effective response to cyber incidents, aligned with frameworks such as ACSC Essential Eight, ISO 27001, APRA CPS 234, and the Australian Privacy Principles (APPs).
  4. Continuously tune detection use cases and integrate cyber defence into broader enterprise risk management.
  5. Act as the frontline guardian—detecting, analysing, and neutralising threats before they impact our members, data, or systems.

About You:

You are a proven cyber defence leader with a strong track record in complex, regulated environments. You bring:

  • 10+ years of experience in cyber security, with a strong focus on cyber threat detection, incident response, and threat intelligence.
  • Demonstrated leadership in building and managing advanced cyber defence functions including SOC operations, threat hunting, red teaming, and detection engineering.
  • Extensive hands-on experience with key threat defence technologies such as SIEM (e.g., Splunk, Microsoft Sentinel), SOAR platforms, EDR/XDR (e.g., CrowdStrike, Defender for Endpoint), and threat intelligence platforms.
  • Proven expertise in security operations within cloud environments (AWS, Azure), including cloud-native threat detection and response capabilities.
  • Strong stakeholder management skills, with the ability to translate technical risk into business impact for non-technical audiences and executive stakeholders.
  • High analytical and mature problem-solving skills.
  • Excellent communication skills, both written and verbal.
  • Deep understanding of security frameworks and threat modelling approaches, including MITRE ATT&CK, NIST 800-61, ASD Essential Eight, and cyber kill chain methodology.
  • Experience leading cyber incident response efforts, including playbook development, root cause analysis, and post-incident review and improvement.
  • Relevant industry certifications such as CISSP, GIAC (e.g., GCIA, GCIH, GDAT), OSCP, or equivalent that reflect strong capabilities in cyber operations, threat intelligence, and technical leadership.

What We Offer:

Medibank values diversity, equity, and inclusion. We strive to make real, fundamental change and believe everyone's potential matters. We encourage applications from everyone, including Aboriginal and Torres Strait Islander candidates, those with disabilities, and LGBTQIA+ community members.
