Engineer III - Sensor, Windows Vulnerability Research & Detection (Remote)

#WeAreCrowdStrike and our mission is to stop breaches. As a global leader in cybersecurity, our team changed the game. Since our inception, our market leading cloud-native platform has offered unparalleled protection against the most sophisticated cyberattacks. We work on large scale distributed systems, processing over 1 trillion events a day with a petabyte of RAM deployed in our Cassandra clusters - and this traffic is growing daily. We’re looking for people with limitless passion, a relentless focus on innovation and a fanatical commitment to developing and shaping our cybersecurity platform. Consistently recognized as a top workplace, CrowdStrike is committed to cultivating an inclusive, remote-first culture that offers people the autonomy and flexibility to balance the needs of work and life while taking their career to the next level. Interested in working for a company that sets the standard and leads with integrity? Join us on a mission that matters - one team, one fight.

About the Role:

CrowdStrike is looking for a Software Engineer III to join our growing Content Research & Exploit Detection team within the Content group, which focuses on emerging vulnerability research, exploit mitigations, and security-related endpoint development on the Windows operating system. 

The Content group plays a central role in fulfilling CrowdStrike’s mission to Stop Breaches. Within the Content Research & Exploit Detection team (CRED), we research the latest common vulnerabilities and exposures (CVEs) to develop tools and techniques that expand sensor visibility and explore ways to detect advanced malicious behavior on customer endpoint devices. Our goal is to enable the sensor to autonomously identify and stop tools, techniques, and procedures where possible, and to provide useful visibility and guidance to security analysts when new previously unknown adversary activity occurs. 

As a software engineer III within the CRED  team, you will be focused on the analysis and development of detection strategies for attack techniques across supported Windows OS versions. You’ll work collaboratively to implement detection logic within the Falcon sensor which includes both user-mode and kernel-mode components that together observe system activity, recognize malicious behavior, provide on-box prevention and remediation capabilities, and send relevant security related telemetry to the Falcon Cloud. You’ll help find creative and resourceful ways to detect Windows specific threats while also helping to develop features that leverage telemetry from common OS subsystems such as: file system, memory, process, and network activity. You’ll get exposure to both user-mode and kernel-mode coding practices. 

As a Software Engineer III, you will also collaborate with a wide range of other teams across the group as you help contribute to team initiatives and assist with operational response requirements. You’ll be expected to make contributions from the initial concept phase through design, implementation, release, and bugtail/support with a focus and passion for sensor performance, testing, and feature support. We're looking for smart people who want to be challenged and take ownership of what they build. 

What You'll Do:

• Recognize common weaknesses and build proof of concepts that can exercise vulnerable code paths.

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

•  Extend our existing codebase and test suites utilizing C, C++, Python, and other tools as appropriate.

• Brainstorm, define, and build collaboratively across multiple teams.

• Obsess about learning, and champion the newest technologies & tricks with others, raising the technical IQ of the team.

•  Deliver and accept feedback with grace and courtesy.

•  Troubleshoot issues within the product when necessary, assisting customer support, test breaks, crash dumps, and release blockers.

•  Leverage your understanding of engineering best practices, including topics like secure coding, testing paradigms, effective peer code reviews, logging, and resilient architecture patterns, to ensure clean, supportable coding practices.

•  Be an energetic ‘self-starter’ who is empowered to take ownership and be accountable for deliverables, both individually and as part of a growing team.

What You'll Need:

•  Post-secondary education in computer science, engineering, or information security OR relevant experience.

•  Low-level OS knowledge of Windows operating system internals, security features, components, APIs, and design.

• Proficiency in multiple programming languages including C, C++, and Python as well as familiarity with multiple processor architectures

• Recent and relevant experience in vulnerability analysis and exploitation techniques,

• Experience in software instrumentation, testing, and code coverage analysis

•  Knowledge of cyber security practices, challenges, tools, and techniques

• Team player – able to lead, mentor, communicate, collaborate, and work effectively in a globally distributed team.

Bonus Points:

•   At least one of the following certifications is desirable:

  •  Offensive Security Certified (OSCP, OSCE, OSEE)

  •  Council of Registered Security Testers (CREST) Registered or Certified Professional certificate

  •  SANS GIAC Penetration Tester, Web Application Penetration Tester, Exploit Researcher and Advanced Penetration Tester

•  Prior experience working with low-level code, such as OS kernel components, minifilters, or device drivers.  

• Understanding of kernel-mode and multi-threaded concurrent systems development in any of our supported platforms, with an interest to grow skills in all of them.

•  Prior penetration testing experience.

•  Prior experience delivering software via agile processes.

•  Prior participation in cyber security challenges (e.g. CTFs).
