ThreatLocker is looking to improve the security of servers and endpoints by developing next-generation threat detection, prevention, and response capabilities on Windows systems.
Requirements
- 5+ years of hands-on experience writing Windows kernel-mode drivers, particularly filter drivers.
- Expert knowledge of Windows system internals (memory management, I/O subsystem, object manager, etc.).
- Proficiency in C/C++, Windows Driver Kit (WDK), and kernel debugging tools.
- Experience in the cybersecurity domain, especially endpoint protection, EDR, anti-malware, or kernel-level monitoring.
- Solid understanding of code injection techniques, hooking, kernel-mode exploits, and mitigation strategies.
- Strong problem-solving skills and a security-first engineering mindset.
- Experience with malware analysis, reverse engineering, or rootkit detection.
Responsibilities
- Design and develop kernel-mode filter drivers (file system minifilter, registry filter, network filter, etc.) to support security monitoring and enforcement.
- Investigate and reverse-engineer Windows internals to implement low-level security features and bypass-resistant protections.
- Collaborate with the threat research, detection, and user-mode engineering teams to develop scalable and stealthy security solutions.
- Perform in-depth kernel debugging, crash dump analysis, and performance tuning using WinDbg, ETW, and related tools.
- Develop robust, secure, and maintainable driver code that meets Microsoft's signing and certification standards.
- Monitor Windows platform changes to ensure compatibility and stability across OS versions.
Other
- Job will generally be performed in an office environment but may require travel to visit company offices and/or property locations.
- Must occasionally lift and/or move up to 25 pounds.
- Specific vision abilities required include close vision, distance vision, depth perceptions, and the ability to adjust focus.
- Bachelor's degree or higher in Computer Science or related field (not explicitly mentioned but implied)
- Must be able to stand, walk, sit, reach with hands and arms, climb or balance, stoop or kneel, talk and hear, and use fingers and hands to feel objects and tools.
