Ready to join a mission that matters? The future of cybersecurity starts with you.
About the Role:
CrowdStrike is looking for a Sr. Software Engineer I 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 Sr. Software Eng 1 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, 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).
