What You’ll Be Working On
Perform deep-dive root-cause analysis of issues across the OS and hardware layers. You will lead the triage and backporting for kernel CVEs while building automated tooling for vulnerability analysis.
Architect and lead critical projects — new kernel features, security patching infrastructure, deployment systems — from design through production and upstream.
Develop kernel code with an upstream-first mindset — we aim to contribute all changes to the Linux kernel community and keep our downstream patches zero; this is a core part of how the team works, not an afterthought
Develop and review kernel code: memory management, scheduler, networking, storage, and GPU-related subsystems
Design and implement advanced virtualization technologies tailored for GPU-accelerated AI and HPC workloads. You will optimize the stack for low latency and high scalability across hypervisors and device emulation.
Find and develop kernel efficiency improvements proactively (e.g., DAMON-based memory management, hugepage optimization, memory overcommit)
Mentor and review work from mid-level and junior engineers
What You’ll Bring to the Team
Deep knowledge of Linux kernel internals — memory management, scheduler, networking, storage subsystems and/or device drivers
Strong C programming skills; fluency in kernel development workflow (patch submission, mailing lists, Lore)
Experience evaluating kernel security vulnerabilities: CVE analysis, exploitability assessment, backporting fixes
Demonstrated ability to set technical direction and drive projects end-to-end
Track record of upstream Linux kernel contributions is a strong plus
Deep knowledge of Linux kernel internals (memory management, scheduler, I/O) and virtualization technologies (KVM, Xen, or QEMU)
10+ years of experience in systems software engineering working on low-level systems or infrastructure teams.
