InfoSec Senior Analyst - Cyber Detection

What’s the Role:
As a Senior Analyst in Detection Engineering, you’ll strengthen Westpac’s cyber threat detection capability by designing and improving how threats are identified and responded to. Working closely with the Cybersecurity Coordination Centre (C3), you’ll reduce detection backlogs, increase visibility of emerging threats, and enable faster, more effective responses to evolving attack techniques. The role spans end‑to‑end detection engineering, from threat hunting and detection design through to testing, tuning, and operationalisation,while also providing technical leadership and mentoring to junior analysts.

Key Responsibilities:

• Design, build and maintain detection content across SIEM, EDR and related security platforms. 
• Develop and refine detection logic, including correlation rules, behavioural analytics and anomaly-based detections. 
• Continuously test, tune and validate detections to improve threat visibility and response effectiveness. 
• Translate threat intelligence and attacker TTPs into actionable detections using frameworks such as MITRE ATT&CK. 
• Work closely with Security Automation, Tooling, Red Team and Security Operations to optimise and validate detection coverage. 
• Support proactive threat hunting activities and contribute to detection knowledge base and documentation.

What do I need?

• Hands‑on experience in cybersecurity or corporate IT, ideally within Detection Engineering, Security Operations or Threat Hunting. 
• Working knowledge of SIEM and EDR platforms, including building and tuning detection content such as correlation rules, behavioural analytics and anomaly detection. 
• Understanding of attacker behaviour and threat models, with the ability to translate threat intelligence into effective detections. 
• Exposure to SOAR technologies and integrated detection‑to‑response workflows. 
• Strong analytical and investigative mindset, with the ability to work independently and collaboratively in a fast‑paced operational environment.  
• Solid technical foundation, including scripting or software development, CI/CD concepts, and database or networking fundamentals; relevant qualifications or certifications are desirable.
