    At CrowdStrike we’re on a mission - to stop breaches. Our groundbreaking technology, services delivery, and intelligence gathering together with our innovations in machine learning and behavioral-based detection, allow our customers to not only defend themselves, but do so in a future-proof manner. Because of that we’ve earned numerous honors and top rankings for our technology, organization and talent. Our culture was purpose-built to be remote first, and we offer flexible work arrangements to help our people manage their personal and professional lives in a way that works for them. If you’re ready to work on unrivaled technology with a team that makes a difference every day, let’s talk.

    About the Role:

    CrowdStrike's Sensor and Language Tooling (SaLT) team is hiring a senior engineer to work on the detection platform for our Falcon sensor. The SaLT team is a group of developers working together on C++, compilers and core security logic. This role focuses on runtime capabilities, and will work closely with the people who expose those capabilities in domain-specific languages and use those languages to build security products.

    CrowdStrike Falcon Host is a two-component security product. One component is a “sensor”: 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 sensor processes thousands of events per second to provide deep visibility into operations on the endpoint, and performs rich correlation and computation to identify malicious events and blocks malicious activity.

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

    CrowdStrike is a remote-first company with offices and developers around the globe. Remote candidates living in the US and Canada are encouraged to apply. Candidates from the UK, EU or Australia are also very welcome to apply, but should know that coordination with US-based teams will be necessary and flexible working hours will be required. For those that prefer office life, CrowdStrike has engineering offices in Irvine (CA), Kirkland (WA), Minneapolis (MN), Sunnyvale (CA), London (UK) and Crystal City (VA). Occasional travel (<10%) is required once the pandemic is over.

    CrowdStrike is a computer security company, but we do not expect candidates for this role to have prior security industry experience. We will mentor and train in security topics as needed. We do expect a strong interest in CrowdStrike's mission and a willingness to grow.
