About the Role:

This role is for a Linux Developer in the engineering team that makes filesystem interactions and metadata visible to detections logic. We work both in the kernel and in user-space, primarily in C++. Since we’re working with the filesystem; performance and stability are crucial, as is understanding when we need to pay attention and when we can get out of the way. The team is cross-platform (Windows, Linux, MacOS), and collaborates closely to produce cross-platform designs and code where possible. Many features are built in a way that they leverage shared components across Windows and Mac, and we want to enable that commonality. Although we focus on filesystem work, we have wide latitude to work on things that need attention or present opportunities, so we’re not limited to the filesystem.

CrowdStrike Falcon Host is a two-component security product. One component is a “sensor”: 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 sensor processes thousands of events per second to provide deep visibility into operations on the endpoint, and performs rich correlation and computation to identify malicious events and blocks malicious activity.

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

CrowdStrike is a remote-first company with offices and developers around the globe. Remote candidates living in the US and Canada are encouraged to apply. Candidates from the UK, EU or Australia are also very welcome to apply, but should know that coordination with US-based teams will be necessary and flexible working hours will be required. For those that prefer office life, CrowdStrike has engineering offices in Irvine (CA), Kirkland (WA), Minneapolis (MN), Sunnyvale (CA), London (UK) and Crystal City (VA). Occasional travel (<10%) is required once the pandemic is over.

What You'll Do:

  • Build elegant, robust, and reliable solutions for complex technical problems on Linux, in both user and kernel space.
  • Be passionate about learning, and champion the newest technologies & tricks with others, raising the technical IQ of the team.
  • Own delivery of systems from start to finish, with a small team of peers - including design, development, testing, performance analysis, and seeing it work in the field.
  • Troubleshoot issues with the product when necessary.
