About the Role:

CrowdStrike Falcon Host is a two-component security product. One component is a “sensor”, which is a driver installed on client machines that observes system activity and recognizes malicious behavior, then provides on-box prevention capability and remote telemetry to the Falcon Host cloud.



The cloud component aggregates sensor telemetry for each customer’s network can correlate malicious behavior across multiple machines and presents our customers’ operations teams with a prioritized summary of the threats detected in their environments.

Join CrowdStrike and become a key leader in building the most creative endpoint security solution in the world. Our sensor development team is responsible for building the endpoint sensor which deploys on multiple platforms including Windows, Mac, and Linux. As a Software Engineer, you will be expected to have ownership over major components and development projects.

You will be required to assist with architecting solutions and support in implementing our core features. Features will cross-cut most core OS subsystems such as file system, memory and process, and networking and will require basic understanding of how AI agents work. Many features are also built in a way that they will have shared components across multiple platforms. You need to be able to lead projects efficiently while maximizing performance and minimizing costs, making sure high standards are being followed when it comes to design, coding quality, and unit and component testing.

- Support development teams in designing and building software with cross-platform deliverables (Windows, Mac, Linux).
- Own features from design to delivery including participation in product demo at the end of the sprint.
- Collaborate with multi-functional teams in various locations across the globe.

What You'll Need:

- Strong low-level OS internals in either Windows, Mac OS, or Linux.
- In depth knowledge with C++ and Windows OS Kernel Development.
- Experience debugging memory corruptions, process contentions and system performance.
- Experience working with teams to ship major features and releases.
- Lead, mentor, communicate, collaborate, and work effectively in a distributed team.
- Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

Bonus Points:

- OS system expertise for core concepts and subsystems such as WFP, TCP/IP, USB, file systems etc.
- Knowledge in Security.
- Strong background in scalable, light-weight and highly performing systems.
- Familiarity with Claude for coding
- Familiarity and experience with Agile process.
