Sr. Engineer - Falcon NG-SIEM, Serverless Cell Platform

Job Description

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.

\n

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.

\n

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

\n

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.

\n

As a Senior Engineer on the NG-SIEM Serverless Cell Platform team, you will be responsible for ensuring the health, performance, and reliability of cell infrastructure - operating the security industry's largest SIEM platform while building the automation and self-healing systems that enable it to scale seamlessly. The NG-SIEM platform is built on a cell-based architecture where each cell is a self-contained LogScale cluster serving customer data.

\n

As we scale toward hundreds of petabytes per day, you will own the operational management of these cells through monitoring, incident response, capacity planning, and continuous improvement - while also developing automation systems that reduce toil and enable the fleet to self-heal. You will participate in follow-the-sun on-call rotations (8x7), perform version upgrades and scaling operations, optimize resource utilization, and write Go microservices that transform manual operational procedures into robust, automated workflows.

\n

You will join a distributed team of high-ownership technical leaders who share a strong passion for our mission: to stop breaches. This role is based in Australia and is fully remote. Many team members are located in Sydney.

• Implement alerting, synthetic test suites, and operational dashboards for rapid troubleshooting and root cause analysis.
\n
• Write Go microservices and automation scripts that transform manual operational procedures into automated workflows, reducing toil and enabling self-healing capabilities.
\n
• Work closely with product engineering and customer support teams to troubleshoot production issues and coordinate changes across the platform.
\n
• Learn and grow through mentorship opportunities, knowledge-sharing sessions, and exposure to large-scale distributed systems engineering challenges.
\n

CrowdStrike was founded in 2011 to fix a fundamental problem: The sophisticated attacks that were forcing the world's leading businesses into the headlines could not be solved with existing malware-based defenses. Founder George Kurtz realized that a brand new approach was needed - one that combines the most advanced endpoint protection with expert intelligence to pinpoint the adversaries perpetrating the attacks, not just the malware. There's much more to the story of how Falcon has redefined endpoint protection but there's only one thing to remember about CrowdStrike: We stop breaches.
