JB-344 Senior Linux Security Developer — Kernel & OS Security

The Role

We are looking for a Senior Linux Security Developer to design and develop security capabilities deep inside the Linux OS — kernel internals, eBPF, OS telemetry, enforcement mechanisms, and security agents. You will own architecture decisions, investigate new attack

surfaces, prototype novel approaches, and turn successful concepts into production technologies.

What You%27ll Do

• Design and implement high-performance Linux security components in kernel and user space %28kernel modules, eBPF, system services, security agents%29, including tamper-resistant mechanisms for adversarial environments.
• Build scalable Linux endpoint capabilities for telemetry, detection, prevention, and policy enforcement.
• Investigate Linux kernel subsystems to find opportunities for new detection and prevention capabilities, including protection of AI-agent workloads %28autonomous processes, tool execution, privilege usage, filesystem/network activity%29.
• Translate research ideas into efficient, production-grade implementations %28performance, concurrency, reliability, security%29, and mentor engineers in systems programming and Linux security.

Requirements

• 6+ years of professional development with significant hands-on C and/or C++.
• 3+ years of Linux kernel development or low-level Linux systems development, with hands-on experience in eBPF/BPF, LSM, kernel tracing/instrumentation, or security frameworks.

• Deep understanding of Linux internals: processes, memory management, scheduling, syscalls, filesystems, networking, kernel/user-space interaction, namespaces, containers.
• Strong debugging and performance analysis skills %28 gdb , perf , strace , ftrace %29.
• Strong concurrency, synchronization, memory management, and performance optimization, building software that runs reliably under high load and adversarial conditions.
• 3+ years in endpoint/host security, malware or vulnerability research, or runtime security.
• Ability to independently investigate unfamiliar areas and turn findings into working prototypes; strong English communication skills.
• Comfortable reading kernel and security source code, analyzing attacker techniques, and validating defenses against performance, coverage, and evasion.

AI-Assisted Engineering

We actively use AI-assisted development tools in our R&D workflow. Experience with AI

coding assistants and agentic tools is an advantage; we value the ability to critically validate

AI-generated code, especially in security-sensitive, low-level software.

Nice to Have

• EDR/XDR agents or endpoint telemetry systems
• Linux exploitation, malware, rootkits, persistence, or evasion techniques
• Linux security mechanisms: SELinux, AppArmor, seccomp, capabilities, cgroups, Landlock
• Container and cloud workload security; exploitation mitigations or runtime security controls
• Reverse engineering, vulnerability research
• Contributions to the Linux kernel, eBPF, or open-source security ecosystem; M.Sc./Ph.D., published research, patents, or talks

Why Join Us?

• Hard problems by design, at the kernel/OS level — research with a path to real products deployed worldwide.
• AI + OS security: help define how autonomous AI agents are monitored, constrained, and protected at the OS level.
• Technical ownership and growth alongside experienced security researchers, with competitive compensation and flexible hybrid work.
