???? Title: Windows Internals Team Leader

???? Locations (Hybrid): Tel Aviv (Sky Tower)

???? Reporting To: CTO

???? Opportunity Highlights

We are seeking a highly skilled and experienced Windows Internals Team Leader to lead a specialized team focused on developing offensive, production-ready attack capabilities. This is a research and development (R&D) role at the core of our offensive security efforts. You will be responsible for architecting and delivering advanced low-level attack components used in evasion techniques, red team tooling, and adversary simulations.

You will be hands-on in both leadership and development, guiding technical direction, mentoring engineers, and contributing code across kernel-mode and user-mode components.

???? The Impact You Will Have

• Lead the design, development, and deployment of production-grade offensive capabilities targeting Windows systems
• Develop low-level Windows components including kernel-mode code, user-mode loaders, and OS-level evasion mechanisms
• Implement Python bindings to connect native low-level components with Python-based research tools and automation
• Debug complex issues in both kernel and user space using tools such as WinDBG and KD
• Research and develop bypass techniques for modern Windows security controls
• Collaborate with the Research Team and other R&D stakeholders to implement and refine offensive concepts
• Provide technical mentorship and drive engineering best practices within the team

Requirements

???? What Sets You Apart

Leadership

• Proven experience as a Team Lead or Technical Lead in an offensive security or R&D environment
• Strong ability to lead complex engineering efforts and mentor a highly technical team
• Experience owning full R&D project lifecycles from concept through production

Technical

• 5+ years of hands-on experience in Windows Internals or kernel-mode development using C and C++
• 3+ years of Python experience, especially for integrating with native modules and supporting research workflows
• Experience developing stealthy and evasive attack components, including in-memory execution and user/kernel-mode tooling
• Proficient in Windows debugging using WinDBG, KD, and similar tools
• Deep knowledge of Windows APIs, security controls, and undocumented behaviors relevant to offensive security
• Familiarity with EDR evasion, API hooking, and direct system call manipulation

Personal Attributes

• Passionate about offensive security and deep technical research
• Self-motivated and capable of operating independently in high-trust environments
• Creative and methodical in problem solving, with a strong attention to detail

???? Even BETTER if you have

• Experience with MITRE ATT&CK and implementing or simulating ATT&CK techniques
• Background in red teaming, adversary emulation, or APT simulation
• Prior contributions to offensive tooling or internal R&D platforms
• Understanding of modern threat actor TTPs and practical application in research environments

Join us to lead the development of real-world offensive capabilities at the intersection of advanced OS knowledge and cutting-edge security research.
