About the Role CrowdStrike's Sensor Security Platform (SSP) team is hiring a Senior engineer to work on the Falcon sensor's foundational detection and response functions. The SSP team's scope and mission exists at the intersection of three broad CrowdStrike missions:
Sensor mission – Where we focus on sensor‑oriented technology implemented primarily on the Falcon Sensor.
Security mission – Where we focus on security‑oriented capability that directly supports the company‑wide mission of stopping breaches.
Platform mission – Where we focus on platform‑oriented technology that is reusable across products and modules and underpins multiple security features.
Some of the domains and technologies in the SSP portfolio are Sensor Classifications, Sensor Detection Pipelines and Templates, Sensor Security Posture and Response, Endpoint User Security as well as Sensor Antitampering. This role is targeting candidates who would work across (and take ownership of) a number of the existing SSP domains and technologies named above.
What You'll Do
Understand, modify and assume shared ownership of complex and critical sensor detections and response capabilities.
Gain expertise in core logic of the Falcon sensor, becoming a resource for other developers within CrowdStrike who use and build on top of the technologies owned by our team.
Communicate design, constraints, guarantees and other aspects of the system.
Collaborate with other teams at CrowdStrike, including engineering teams who use our tools; adversary response teams; malware researchers; product and program managers; and others.
Write code in a variety of languages, including internally developed, non‑imperative domain‑specific languages. Much, but not all, of the work we need will be written in the in‑house language, which is highly asynchronous and used to write responses to system events such as process creation and network traffic. System programming experience on macOS, Linux, and Windows is helpful.
Write unit, functional and integration tests.
Diagnose and resolve issues discovered by customers or other engineering teams.
What You'll Need
Take responsibility for and ownership of your work.
Design and implement performant, functionally‑correct and well‑structured logic.
Understand, maintain, and improve a large existing codebase.
Reason about, describe and communicate the nature of complex, highly‑concurrent systems.
Reason about how our endpoint interacts with our cloud, and communicate with cloud development teams for both design and troubleshooting.
Ability to read and write C++ (though this is not primarily a C++ position).
Communicate, collaborate, and work effectively in a distributed team across timezones and continents, and with a variety of subject‑matter expertise.
Bonus Points
Fluency and expertise in Linux development environments.
Fluency in writing Python.
Endpoint security background.
Experience designing or writing virtual machine runtimes.
Benefits of Working at CrowdStrike
Remote‑friendly and flexible work culture.
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.
