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.

• Collaborate with multi-functional teams in various locations.

What You'll Need:

• In depth knowledge with C++ and Windows OS Kernel Development.
• Strong low-level OS internals in either Windows, Mac OS, or Linux.
• Experience debugging memory corruptions, process contentions and system performance.
• Experience working with teams to ship major features and releases.
