Stage Early-stage startup backed by tier 1 investors. Small, growing team with exceptionally high ownership.
- + Discover and exploit vulnerabilities in Windows kernel-mode and user-mode drivers.
- + Research attack surfaces across WDDM display drivers, network miniport drivers, filesystem filter drivers, and third-party kernel extensions.
- + Develop exploit primitives for privilege escalation, sandbox escape, and kernel code execution.
- + Build automated tooling for Windows driver analysis, fuzzing, and vulnerability triage.
- + Deep experience with Windows kernel internals: I/O manager, object manager, memory manager.
- + Proven track record of driver vulnerability research (CVEs, ZDI submissions, or security research).
- + Strong x86/x64 reverse engineering and exploit development skills.
- + Proficiency with WinDbg, IDA/Ghidra, and driver analysis frameworks.
Nice to Have
- + Experience with Hyper-V and virtualization-based security (VBS) attack surfaces.
- + Familiarity with Windows driver fuzzing (kAFL, what the fuzz, custom harnesses).
- + Experience with BYOVD (Bring Your Own Vulnerable Driver) attack techniques.
- + Knowledge of Windows Defender / EDR kernel-mode components.
- + Experience building with LLMs and AI agents.
- + Published research or conference talks on Windows kernel security.
- + Deeply technical and motivated to find the bugs that matter at the kernel level.
- + Clearly interested in stepping away from purely manual research and moving toward the development of AI systems.
- + Building something massive matters more to you than comfort, titles, or predictability.
- + You want to be early at a company that will change an industry, and you're ready to do what that actually takes.
Note to recruiting firms: Windows driver vulnerability research is the core requirement. Kernel security experience is essential. Familiarity with modern Windows security mitigations is a strong plus.
