About the Role:
In this role you will research and develop techniques for detecting malicious activity occurring on macOS systems. Once researched you will develop 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 MacOS engineers and often leveraging shared code with other sensor platforms such as Windows and Linux.
Successful engineers in this role have: an understanding of macOS 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.
What You'll Do:
Design and build detection logic and systems leveraged across teams within CrowdStrike to detect cyber attackers and stop breaches
Extend our existing codebase utilizing Swift, C++, Python, and other tools and DSLs (domain specific languages) as appropriate
Research techniques for detecting malicious activity including some reverse engineering and/or big data analysis
Leverage your understanding of engineering best practices, including topics like secure coding, testing paradigms, debugging, performance, code reviews, CI/CD and os internals, to ensure that our sensor code is fast and reliable
Troubleshoot issues with the product as reported from customers responsively and other projects as assigned
Be an energetic ‘self-starter’ with the ability to take ownership and be accountable for deliverables, both individually and when leading a team
What You'll Need:
5+ years of experience with either:
Reverse engineering, threat detection, and malware analysis; and an interest in on-device development, or
Designing, building, and delivering high-quality software in at least one of the following: Swift, C/C++, Python, Objective-C; and an interest in security.
Low-level OS knowledge of macOS and/or Linux operating system internals, components, APIs and/or frameworks.
Team player – able to lead, mentor, communicate, collaborate, and work effectively in a distributed team, to clearly articulate thoughts & designs to peers and upper management
Bonus Points:
Prior security experience, particularly in endpoint threat detections or sensor development. Familiarity with the threat landscape on Linux/Windows is a plus
Experience with macOS Frameworks and events relevant to security and recent familiarity with the recent developments in macOS
Experience developing 24/7 enterprise software, including CI, testing, debugging, performance tracing, release management, telemetry analysis and issue handling
