Sr. Engineer II, DevOps, NG-SIEM (Remote, AUS)

As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission hasn't changed - we're here to stop breaches, and we've redefined modern security with the world's most advanced AI-native platform. We work on large scale distributed systems, processing almost 3 trillion events per day and this traffic is growing daily. Our customers span all industries, and they count on CrowdStrike to keep their businesses running, their communities safe and their lives moving forward. We're proud to work for a mission-driven company leveraging AI to transform the way we work. CrowdStrikers drive their careers through flexibility and autonomy while also being expected to contribute to a culture of responsible AI adoption, experimentation, and innovation. We use an AI-first mindset as a force multiplier to proactively and continuously accelerate execution, build expertise, uncover insights, and solve complex problems. We're always looking to add talented CrowdStrikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other. Ready to join a mission that matters? The future of cybersecurity starts with you. 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. What You'll Do: End-to-end observability: Design, build, and maintain monitoring and synthetic test suites that provide deep visibility into the health of the entire NG-SIEM pipeline - from ingest through search and workflow execution - enabling rapid root cause analysis across component boundaries. Coordinated scaling: Engineer orchestrated scaling solutions that treat the NG-SIEM pipeline as a unified system, proportionally increasing resources across all dependent components (Kafka, ingest pipelines, downstream services) to eliminate cascading bottleneck patterns. Incident response engineering: Serve as a subject matter expert during platform-wide incidents (P2 and above), applying cross-service knowledge to diagnose and resolve multi-component failures. Partake in follow-the-sun on-call rotations, providing incident commander coordination for critical platform-wide events. Capacity planning and cost management: Build and refine models for end-to-end capacity forecasting that account for all pipeline dimensions, including partner team dependencies (data services, GPS). Develop tooling to continuously track and surface cost drivers across the platform. Automation and runbooks: T
