About the Role

KayHut is looking for an experienced R&D Team Lead to head a talented group of engineers developing critical components for an advanced security solution running on Windows. Our core product is a C++ agent deployed on customer endpoints, supported by robust Python infrastructure.

This is a hands-on leadership role combining technical excellence with team management. You’ll work closely with our Core, Research, and Module teams to develop features in both User Mode and Kernel Mode, while ensuring top-tier software quality, reliability, and performance. We operate in a modern CI/CD environment using Docker and automation pipelines.

What You'll Be Doing

• Lead and mentor a team of 4–5 experienced software engineers

• Own end-to-end development processes: research, design, coding, testing, and deployment

• Collaborate with cross-functional teams across a ~5-team R&D group

• Set coding standards and best practices for C++ and Python in both user and kernel space

• Design and maintain CI/CD processes for mission-critical system components

• Ensure code quality, documentation, and robust review processes

• Communicate with external partners and customers when needed

Requirements

• 2+ years of experience leading R&D teams (technical + personal management)

• 5+ years of hands-on software development experience

• Strong command of C++ (including STL, multithreading, design patterns)

• Proven experience with Python

• Deep understanding of Windows internals, user/kernel mode architecture

• Background in developing low-level system components or endpoint agents

• Experience with CI/CD tools and Docker (GitLab, Jenkins or similar)

• Ability to independently own and drive features end to end

• Passion for clean, secure, and testable code – with a focus on safe upgrades and monitoring

Nice to Have

• Experience in cybersecurity products or client-side software

• Background in reverse engineering or cyber research

• Experience developing Windows kernel drivers

• Familiarity with distributed systems or large-scale cloud projects

• Background in elite tech units (e.g., 8200) or strong ties to the Israeli security/cyber community
