Our mission is to make all of our customers' security-relevant data continuously available for automated detection and response, threat hunting, and other Falcon use cases. To enable this, the systems behind NG-SIEM 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.
As our new NG-SIEM Site Reliability Engineer, you'll be responsible for ensuring the reliability, performance, and scalability of our serverless platform that delivers this massive scale to customers and other Falcon modules. You'll work on improving system observability, automating operational tasks, optimizing resource utilization, and maintaining our stringent SLOs while balancing cost efficiency. This role requires deep technical expertise in distributed systems, cloud infrastructure, and a passion for operational excellence.
