Linux Kernel Security Engineer

About the Role We are seeking a highly skilled Linux Kernel Security Engineer to join our cybersecurity defense research team. The ideal candidate will have deep expertise in Linux internals, strong C/C++ programming skills, and hands-on experience in analyzing vulnerabilities, developing system-level security tools, and contributing to the hardening of Linux-based infrastructure. This is a unique opportunity to be part of a forward-looking security team focused on proactive threat mitigation, vulnerability research, and system integrity enhancement. Responsibilities System Security Research & Development Analyze historical and emerging Linux vulnerabilities (CVE research and impact assessment). Design and implement kernel-level monitoring and protection tools. Develop secure and efficient Linux Kernel Modules (LKMs) for detection and defense purposes. Research modern techniques for system integrity, syscall behavior analysis, and runtime protection. Security Engineering & Tooling Build low-level system utilities using C/C++ for security visibility and resilience. Enhance Linux infrastructure with custom security modules, syscall instrumentation, and auditing tools. Collaborate with infrastructure and DevSecOps teams to ensure secure system-level deployments. Risk Analysis & Hardening Evaluate system behavior under potential attack scenarios in a controlled and defensive context. Recommend mitigations for vulnerabilities in kernel space and userland boundaries. Support the implementation of hardening configurations and kernel security features such as SELinux, AppArmor, and seccomp. Documentation & Reporting Document technical findings, tools, and system modifications clearly and professionally. Create detailed reports for internal teams and contribute to secure development guidelines. Eligibility Education Bachelor’s degree in Computer Science, Cybersecurity, Information Security, or a related field. Postgraduate degree or relevant research experience is an added advantage. Technical Skills Strong understanding of Linux Kernel architecture, including: System call interface Process and memory management Filesystems and device drivers Strong proficiency in C and C++ for both kernel-space and user-space development. Experience with: Socket programming and Linux networking stack Kernel debugging tools such as gdb, ftrace, kprobes, and perf Building and maintaining Loadable Kernel Modules (LKMs) Security Experience Familiarity with Linux vulnerability analysis, CVE assessment, and secure coding practices. Understanding of kernel hardening techniques, mitigations, and runtime protections. Knowledge of threat modeling and defensive strategies at the operating system level. Desired Eligibility Certifications (Preferred) OSCP, OSEP, or equivalent advanced security certifications. LFD420 (Linux Kernel Internals – Linux Foundation). Additional Linux or security-focused certifications are a plus. Desirable Skills Experience with secure Linux deployment models. Knowledge of Mandatory Access Control (MAC) systems such as SELinux and AppArmor. Experience with container runtime security, including seccomp-bpf and namespaces. Contributions to open-source security tools or Linux kernel projects. Background in participating in security research communities or CTF platforms is preferred. Travel Travel may be required across the country for project execution, monitoring, and coordination with geographically distributed teams, as and when required.
