CrowdStrike is hiring a Senior Software Development Engineer II for the CTIO Linux sensor team. The role focuses on designing and implementing core sensor features across OS subsystems (file system, memory, process, networking) using C/C++ with strong Linux internals and debugging skills. Hybrid positions are based in Redmond, WA; Sunnyvale, CA; Austin, TX; New York, NY; or Toronto. The posting includes a US base salary range of $160,000–$250,000/year and a Canada range of $175,000–$250,000 CAD/year.

Role involves developing file format parsers and feature extraction engines, implementing and testing robust libraries/SDKs and APIs, collaborating with data scientists on ML features, performing reverse engineering and malware analysis, and working across Windows/macOS/Linux. Requires ~12+ years experience with Rust/C/C++/Python and familiarity with CI/CD and cloud platforms.

Work on the Falcon Host sensor (kernel-mode driver) and related cloud telemetry features. Responsibilities include designing, implementing, and owning cross-platform sensor features (Windows primary, also Mac/Linux), debugging low-level issues (memory corruption, process contention, performance), collaborating with distributed teams, and mentoring others. Requires strong C++ and Windows kernel/OS internals expertise; preferred experience with WFP, TCP/IP, USB, file systems, Agile and Git.
