Sr. SRE Engineer II - EPICS, NG-SIEM (Hybrid, Sydney)

About the role

Our mission is to make all of our customers' security-relevant data continuously available for automated detection and response, threat hunting, and other Falcon platform use cases. To enable this, the systems behind NG-SIEM (next-generation security information and event management) are growing to accommodate >100 PB of event and action data ingested every day, up to 10 years of retention, and dozens of millions of queries per hour across large sections of the data stored, for tens of thousands of customers. As a Senior Engineer II on the newly established NG-SIEM EPICS (End-to-End Performance, Incident-response, Cost, and Scaling) team, you will own the reliability and scalability of the security industry's largest SIEM platform - treating these as software engineering problems rather than purely operational ones. The NG-SIEM platform comprises many decoupled components interacting across complex pipelines. As we scale, ensuring end-to-end health across ingest, search, and workflow execution requires deep cross-service expertise and coordinated action. You will be the engineer who builds the observability, automation, and scaling systems that keep the entire platform performing - not just individual components. You will join a distributed team of high-ownership technical leaders who share a strong passion for our mission: to stop breaches. This is a hybrid opportunity, with the expectation to be in our Sydney office (Level 18, 141 Walker Street, North Sydney) 2-3x a week.
