Software Engineer III - Cloud in London

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.

We are seeking a talented Cloud Software Engineer to join our growing Threat Detection and Incident Response (TDIR) team and help revolutionize security management with our AI-native Falcon Next-Gen SIEM platform – enabling customers to detect, investigate, and hunt down threats 150x faster at Petabyte scale within a unified platform to stop breaches.

You will be designing and developing world-class case management and investigation capabilities in Golang that empower security analysts to be more effective at incident response, threat hunting, and collaborative investigations. You will build intelligent workflows that connect detections, evidence, and response actions into cohesive cases, while leveraging advanced correlation, contextual enrichment, and AI/ML-powered insights. You will also have opportunities to explore applied AI and agentic AI capabilities - such as intelligent case prioritization, automated investigation suggestions, and AI-assisted analyst workflows that help security teams work smarter and respond faster to emerging threats.

Have no fear if you don’t have prior experience with Golang or the security industry – we value the desire to learn, the ability to write and ship high-quality code, and the passion for seeing your solutions deployed in production. We will mentor and train you in security topics as needed, and expect you will be comfortable collaborating with awesome colleagues and partner teams distributed across various geographies and time zones. What we do look for is a strong interest in CrowdStrike's mission and a willingness to engage with the needs of our product teams and customers.
