About the role

We are seeking a highly skilled CNO Developer with strong reverse engineering capabilities to support advanced research, systems development, and threat analysis.

Responsibilities

• Design, develop, and maintain low-level kernel-mode components, drivers, and subsystems for Windows platforms.
• Perform reverse engineering of Windows binaries (both legitimate and malicious) to understand system behavior, exploits, or undocumented APIs.
• Conduct vulnerability research and proof-of-concept exploit development.
• Analyze crash dumps, root cause bugs, and provide kernel-level debugging and troubleshooting support.
• Collaborate with cybersecurity researchers, analysts, and software engineers to support security-focused development efforts.
• Document findings, architecture, and procedures clearly for internal teams or external clients.

• Bachelor’s or Master’s degree in Computer Science, Computer Engineering, or a related field (or equivalent experience).
• Previous experience in Windows kernel development.
• Proficient in C/C++ for systems-level programming.
• Expertise with reverse engineering tools such as IDA Pro, Ghidra, x64dbg, WinDbg, and Hex-Rays.
• In-depth understanding of Windows internals (e.g., kernel-mode drivers, memory management, system calls, PE file format).
• Experience with kernel-mode debugging and root cause analysis.
• Familiarity with secure coding practices and low-level exploit mitigation techniques (e.g., PatchGuard, CFG, DEP/ASLR).
• Strong understanding of malware behavior and techniques.
