Sr. Engineer – Sensor (Remote)

USA – Remote

As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission hasn’t changed — we’re here to stop breaches, and we’ve redefined modern security with the world’s most advanced AI-native platform. We work on large scale distributed systems, processing almost 3 trillion events per day. We have 3.44 PB of RAM deployed across our fleet of C* servers – and this traffic is growing daily. Our customers span all industries, and they count on CrowdStrike to keep their businesses running, their communities safe and their lives moving forward. We’re also a mission-driven company. We cultivate a culture that gives every CrowdStriker both the flexibility and autonomy to own their careers. We’re always looking to add talented CrowdStrikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other. Ready to join a mission that matters? The future of cybersecurity starts with you.

About the Role:

Trillions of events flow through Falcon sensors into CrowdStrike’s clouds every day. On the Unified Search team, we research, design, and develop ways to minimize both human effort and resource consumption in the search for patterns in this massive and ever-growing quantity of data. We’re looking for an enthusiastic colleague to join us on this ambitious effort.

The Unified Search team focuses on languages and execution environments to detect malicious behaviors across multiple kinds of platforms, from the cloud to individual customer machines. Typical problems from past projects have ranged from very low level to high level abstractions, from considering CPU cycles per character to developing abstract models for future query execution.

Our highly collaborative team is distributed across the United States. CrowdStrike is a remote first company but for those who may prefer working from an office, CrowdStrike has engineering offices in Kirkland WA, Sunnyvale CA, Irvine CA, Arlington VA, and Minneapolis, MN. Occasional travel (<10%) is required.

CrowdStrike is a computer security company, but we do not expect candidates for this role to have prior security industry experience. We will mentor/train in aspects of the security world as required. We do expect a strong interest in CrowdStrike’s mission and a willingness to learn about the industry and our techniques.

We are looking for a colleague to develop and maintain a specialized execution environment for running detection logic produced by the Unified Search team’s compilers. This execution environment is written in C++ and expert level experience with C++ is essential.

What You’ll Do:

Design and develop a highly performant runtime for a low latency event-driven architecture
Collaborate with colleagues focusing on language and compiler design
Own features from design to delivery to sustained care after release
Serve as low level execution and performance expert for the team
Collaborate with other teams on cross functional design
Understand the larger system architecture and its impact on development and design

What You’ll Need:

Expertise with C/C++, particularly in developing and debugging a kernel level asynchronous event driven codebase
Kernel module development experience, such as device drivers or kernel mode components
Willingness to develop for multiple operating systems including but not limited to Windows, macOS and Linux
Testing: unit testing, integration / end-to-end testing, and associated automation
Deliver and accept feedback with grace and courtesy
Experience in multi-threaded concurrent systems development: what problems do concurrent systems pose and how do you solve them?
Comfortable working on a distributed team with multiple time zones

Bonus Points:

Experience developing code within a well-defined information architecture
Code optimization and performance assessment/profiling/testing
Familiarity with reading assembly language, specifically x64 and/or ARM.
Experience with Python
Prior experience developing design tools, tests, and/or test automation.
Prior experience with pytest, Jenkins or Bamboo in a CI/CD environment
Knowledge of low-level operating system internals for one or more of our supported platforms (including Windows, macOS, and Linux).
Experience with real-time and/or embedded operating systems.
Experience developing software for high-assurance, safety critical, or life critical domains
Experience with developing for cloud-based or other highly concurrent, highly distributed systems
Familiarity with one or more query/business intelligence languages (SQL, Splunk SPL, etc.)
Familiarity with generative or formal software methods: model based development, domain specific languages, formal modeling. For example, we’ve used tools like TLA+, Z3, Agda, and domain specific languages in the past to ensure safety and robustness in our designs.
