Cyber Threat Intelligence Specialist

r Security team, responsible for leading the organisation's threat intelligence capability. This includes the operation and enhancement of the MISP platform, advanced analysis of external threat feeds, and the production of actionable intelligence to support vulnerability management, incident response, and strategic risk decisions.

You will maintain awareness of adversary tactics, indicators of compromise, and emerging vulnerabilities by correlating information from ACSC CTIS, CISA Known Exploited Vulnerabilities, the US National Vulnerability Database, and other curated MISP feeds. Intelligence outputs will directly inform the Security Risk Management Plan, threat models, and continual improvement cycles.

This is a hands-on position focused on platform operation, feed management, and threat analysis. You'll also be responsible for documenting intelligence products that are traceable, actionable, and relevant to the supported environment, while also contributing across broader security operations.

This role requires flexibility, collaboration, and a willingness to support team objectives across all areas of cyber defence while still focusing on Cyber Threat Intelligence.

Key Responsibilities

• Operate and maintain the MISP threat intelligence platform, integrating structured threat feeds and known malware indicators, while tuning feeds to improve the relevance and quality of threat data.

• Correlate threat intelligence with known vulnerabilities and incident data to support prioritised mitigation, patching, and risk-based decision-making across the environment.

• Generate high-quality intelligence outputs, including threat profiles, risk narratives, contributions to the Security Risk Management Plan (SRMP) and other audit-ready documentation.

• Provide enriched indicators of compromise and attribution context during incident response activities, supporting containment and recovery efforts in collaboration with internal and customer security teams.

• Actively contribute to broader cyber security operations, supporting incident response, vulnerability management, endpoint security management, compliance activities, and continuous improvement initiatives as part of a small, cross-functional team.

Qualifications & Experience

• Proven experience operating or administering MISP or a similar Threat Intelligence Platform (TIP) in a production environment, with a strong understanding of platform integration and maintenance.

• Familiarity with cyber threat intelligence standards and frameworks such as STIX, TAXII, MITRE ATT&CK, and the Cyber Kill Chain, and their application in real-world threat analysis.

• Practical experience working with structured threat feeds and enrichment sources (e.g., CVE/NVD, CTIS, CISA KEV), and applying this intelligence to support vulnerability and incident response workflows.

• Strong written communication skills, with the ability to produce clear, actionable threat intelligence artefacts, technical documentation, and operational advisories for diverse audiences.

• A collaborative and inclusive approach to cyber defence, with a passion for continuous learning, teamwork, and contributing to a shared security mission as part of a wider team.

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