Job Description

Senior Kernel Software Developer

Our cybersecurity client builds advanced technologies that form the foundation of digital resilience. Their platform empowers enterprises to defend critical infrastructure against sophisticated adversaries by engineering protection at the deepest levels of the operating system. Through kernel-level innovations, they ensure stability, performance and security without compromise.

They are looking for a SENIOR KERNEL SOFTWARE DEVELOPER with deep expertise in Windows internals and driver engineering and cybersecurity experience. This individual will architect and maintain low-level system components that serve as the cornerstone of their security platform. You will be at the forefront of creating advanced defense capabilities that operate where attackers least expect resistance - the kernel.

Core Responsibilities

• Architect and implement Windows kernel-mode drivers (file system, registry, network, and related filter technologies) to enable monitoring, policy enforcement, and defensive controls.
• Research and leverage Windows operating system internals to design robust, bypass-resistant protections.
• Collaborate with research teams, user-space developers, and product engineers to integrate kernel-level modules into broader security workflows.
• Perform advanced debugging and crash analysis, using tools such as WinDbg, ETW, and custom diagnostics to identify root causes and performance bottlenecks.

Required Qualifications:

• Prior exposure to the cybersecurity sector
• Minimum 5 years of professional experience in Windows kernel development, with a focus on driver and filter driver design.
• Expert-level understanding of Windows internals (memory management, I/O processing, process and thread management, object manager, etc.).
• Strong proficiency in C/C++, Windows Driver Kit (WDK), and modern kernel debugging methodologies.
• Proven experience within the security space—such as EDR, anti-malware, intrusion detection, or kernel-based monitoring solutions.
• Familiarity with exploitation techniques, hooking, and rootkit behaviors, combined with strategies to counter them.
• Demonstrated ability to engineer secure, reliable, and high-performance kernel modules.

Preferred Expertise

• Background in reverse engineering, malware research, or kernel exploit analysis.
• Experience with Microsoft WHQL testing, driver signing, and kernel submission pipelines.
• Contributions to security research communities, open-source kernel projects, or technical publications.
• Knowledge of secure development lifecycle practices and defensive coding strategies for low-level software.

Why is This a Great Opportunity

• Cutting-Edge Technical Mission - You get to work at kernel level, deep in the OS, designing low-level security infrastructure and solving hard engineering problems, doing “real” technical work rather than just surface-level features.
• Strong Growth Potential & Learning Curve
• High Impact Role
• Collaboration & Cross-Functional Integration
