Principal Kernel Engineer

Join our kernel team, in charge of the network segmentation: building real-time kernel-level enforcement and telemetry for next-generation security products, as well as a new AI Detection and Response (AI-DR) initiative. Youll develop production-scale software across Linux, Windows, and other platforms, solving complex security challenges. As part of the small senior leaders of the team, youll have a direct impact on the product and its technical direction.As a Principal Kernel Engineer , you will be responsible for:Writing and debugging kernel-level C code across our Linux kernel module, Windows kernel driver, and eBPF programs.Owning end-to-end debugging of complex production issues, including kernel crashes and low-level system failures, while driving root-cause analysis and post-mortems for production environments.Acting as the technical lead for a small team by reviewing critical kernel/eBPF code mentoring engineers, unblocking complex issues, and guiding key technical decisions.Requirements: Have 5+ years of production C, most of it at the kernel or driver level.Have proven production experience with Linux kernel, Windows drivers, or eBPF.

Experience across multiple areas is highly preferred.Have Hands-on eBPF experience, including writing programs, working with the verifier, and ensuring cross-kernel portability.Demonstrate solid understanding of kernel fundamentals, including concurrency, memory safety, and low-level debugging.Have experience with kernel software operations, including driver signing, Secure Boot, cross-kernel compatibility, and CI for multi-version environments.Possess deep technical judgment and the ability to identify potential issues in kernel code before they reach production.Have exceptional ability to debug kernel crashes and other severe bugs.This position is open to all candidates.
