About the Team

The Defence pod at Xero is the Detection Engineering Team within Security Operations. As a core component of proactive threat defence, this specialized group focuses on designing, developing, and refining detection capabilities to identify potential security threats swiftly and accurately.

Leveraging cutting-edge technologies, data analytics, and deep security expertise, the team creates and fine-tunes detection rules, threat hunting methodologies, and automated workflows.

    • Build tools and scripts to automate repetitive tasks, create custom detection mechanisms, and integrate platforms for streamlined workflows.
    • Experiment with new technologies, techniques, and machine learning models to advance detection capabilities.
    • Iteratively refine detection logic based on attack simulations and post-incident reviews to address gaps and improve resilience.
    • Stay updated on the latest threat actor tactics, techniques, and procedures (TTPs) and incorporate them into detection strategies.
    • Collaborate with response teams during investigations by providing insights, creating custom queries, or adjusting detections in real time.
    • Build scripts, dashboards, and playbooks to streamline and enhance detection and investigation processes.

Requirements:

    • Relevant engineering experience building and deploying solutions in a production environment on Google Cloud Platform (GCP)
    • Experience with Python
    • Experience with SOAR tools
    • Understanding of Security Operations Centre (SOC)
