Engineer III - Linux Sensor (Hybrid)

Content Development (CD) is a team within the Endpoint Protection area of CrowdStrike-the area responsible for enabling detections and preventions of malicious behaviors on the Falcon Platform. The CD team focuses on strategic, forward-leaning research into new Falcon Sensor capabilities to identify the tactics and techniques used by adversaries.

We accomplish this by focusing on OS security and internals across all major supported platforms (Windows, macOS, and Linux) and exposing the right data to the sensor in a supportable and performant manner. Most of our projects involve months of research, planning, coordination, and implementation to be successful. We currently support several key Falcon Sensor technologies that detection and response teams leverage to increase telemetry, detections, and preventions on the platform.

- This is a hybrid role based out Redmond, WA, Sunnyvale, CA, Austin, TX, NYC, or Toronto with an expectation of being in the office at least 2 days per week.

In this role, you will research and develop techniques for detecting malicious activity on Linux systems, then build them into production-level solutions for deployment in the endpoint sensor. The role is a split of research and implementation, working alongside a small and nimble group of Linux engineers and often leveraging shared code with other sensor platforms such as Windows and macOS.

Successful engineers in this role have an understanding of Linux kernel and user space, a passion for continuous learning to keep up with an ever-changing threat landscape, a creative mindset for designing new detection methods, and the discipline to write fast and reliable code.

- The sensor is a lightweight agent installed on client machines that observes system activity, recognizes malicious behavior, provides on-box prevention, and sends remote telemetry to the Falcon Host cloud. It processes thousands of events per second to deliver deep visibility into endpoint operations and performs rich correlation and computation to identify and block malicious activity.

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

Engineers on the team own the design and development of core platform features that cut across most core OS subsystems-file system, memory, process, and networking. The team operates under Agile development principles and ships frequently.

- Design and build detection logic and systems leveraged across teams within CrowdStrike to detect cyber attackers and stop breaches

- Research techniques for detecting malicious activity, including some reverse engineering and/or big-data analysis

- Own features from design to delivery, developing them into production-level solutions for deployment

- Apply engineering best practices-secure coding, testing paradigms, debugging, performance, code reviews, CI/CD, and OS internals-to ensure our sensor code is fast and reliable

- Collaborate with a cross-functional team spread across geographies

- Respond to and troubleshoot product issues reported by customers

- Be an energetic self-starter with the ability to take ownership and be accountable for individual deliverables

- Reverse engineering, threat detection, and malware analysis, and an familiarity with on-device development, or

- Designing, building, and delivering high-quality software in C/C++ (and ideally similar languages), and an familiarity or proven interest in security

- Solid knowledge of Linux OS internals: processes, storage, networking, and memory management

- High-concurrency requirements with strong use of multi-threading

- Detailed low-level operating requirements (memory usage, efficient performance, standards conformance)

- Ability to deliver enterprise software while collaborating across functions: CI, testing, debugging, performance tracing, release management, big-data telemetry analysis, and issue handling

- Team player-able to lead, mentor, communicate, collaborate, and work effectively in a distributed team, and to clearly articulate thoughts and designs to peers and upper management

- Familiarity and ideally experience with Linux kernel programming and/or eBPF

- Prior security experience, particularly in endpoint threat detection or sensor development, including on other operating systems (macOS, Windows)

- Familiarity with recent developments in the Linux threat landscape

- Experience developing and delivering 24/7 enterprise endpoint software
