Original 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. 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:

The Falcon sensor is the front line of CrowdStrike's platform. Running as a lightweight agent on millions of endpoints, it observes system activity in real time, stops malicious behavior on the device, and streams telemetry to the cloud, where it's correlated across customers' environments to surface and prioritize threats.

The Core Windows team owns the kernel-mode foundation and user-mode low level system frameworks of the Falcon sensor on Windows: the drivers and event sources that give CrowdStrike deep visibility into file system, registry, process and network activity, and the mechanisms that let the sensor act on that in real time. These components run at the lowest level of the operating system on every Windows endpoint CrowdStrike protects.

As a Senior Engineer II on this team, you'll own the design and development of core capabilities in both kernel and user mode that cut across the major OS subsystems, including memory management. Many of these capabilities share components with the Linux and macOS sensors. Because this code runs on every protected Windows endpoint, performance, stability, and correctness are first-class requirements.

This is a systems software role. You'll work close to the OS, reason carefully about behavior under real-world load, and hold a high engineering bar in a codebase where reliability is non-negotiable. You'll collaborate closely with peer engineers on the macOS and Linux teams, and with many other teams inside and outside the core organization.

What You're Stepping Into

You'll join a tight-knit team of deep Windows kernel and system software engineers with a strong track record of delivering complex, cross-team initiatives without lowering the quality bar. The team's scope is expanding, and it holds a central role in shaping the next generation of the Falcon sensor on Windows. That means real ownership early: you won't be maintaining a corner of the codebase, you'll be helping decide where it goes next.

What You'll Do

Design, develop, and own kernel-mode and lower level system software components of the Windows sensor, from design through delivery and production validation
Partner on sensor architecture and technical strategy for endpoint detection and response (EDR) capabilities
Build software with cross-platform deliverables in collaboration with Linux and macOS engineers
Drive design reviews and provide substantive code review that raises the bar for the team
Diagnose and resolve complex production issues and customer escalations, including crashes, hangs, and performance regressions
Improve the test infrastructure and tooling that keep kernel-mode code reliable as it evolves
Mentor other engineers and collaborate effectively with multi-functional teams across locations

What You'll Need

In-depth knowledge of C/C++ and Windows kernel and driver development (e.g., minifilter drivers, kernel callbacks, kernel/user-mode communication)
Strong low-level Windows OS internals: processes and threads, memory management, the I/O subsystem, and the security model
Experience debugging memory corruption, deadlocks and resource contention, and system performance problems, including crash dump analysis with WinDbg
Experience shipping major features and releases as part of a team
Ability to lead, mentor, communicate, and work effectively in a distributed team
Willingness to travel occasionally for team offsites and in-person collaboration
Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

Bonus Points

Experience with Windows Filtering Platform (WFP), Event Tracing for Windows (ETW), or other kernel-mode telemetry sources
Background in endpoint security, EDR, or anti-tamper technologies
Strong background in scalable, lightweight, high-performance systems
Low-level OS internals experience on macOS or Linux
Familiarity with Agile development practices

Benefits of Working at CrowdStrike:

Market leader in compensation and equity awards
Comprehensive physical and mental wellness programs
Competitive vacation and holidays for recharge
Paid parental and adoption leaves
Professional development opportunities for all employees regardless of level or role
Employee Networks, geographic neighborhood groups, and volunteer opportunities to build connections
Vibrant office culture with world class amenities
Great Place to Work Certified™ across the globe
