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 also a mission-driven company. We cultivate a culture that gives every CrowdStriker both the flexibility and autonomy to own their careers. 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:
Have you spent hours arguing about tabs versus spaces? Does correlating and analyzing data at massive trillions-of-events-per-day scale excite you? Do you care deeply about cybersecurity and want to play an active role in helping secure organizations from cyberattacks? Hi, we’d like to meet you.

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'll 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'll 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'll 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'll mentor and train you in security topics as needed, and expect you'll 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.

Where to Advertise Cyber Security Jobs in the UK (2026 Guide)

Advertising cyber security jobs in the UK requires a different approach to most technical hiring. The candidate pool is small, heavily vetted and in high demand across government, financial services, critical national infrastructure and the private sector simultaneously. Many of the strongest candidates hold active security clearances, are not actively job-searching through general platforms, and move primarily through specialist networks and trusted referrals. General job boards reach a broad audience but lack the specificity that security professionals expect. Specialist platforms, government-affiliated channels and cleared candidate networks each serve a different part of the market. This guide, published by CybersecurityJobs.tech, covers where to advertise cyber security roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.
