Staff Linux Kernel EngineerNew$215K–$260K

The opportunity

Crusoe is on a mission to accelerate the abundance of energy and intelligence . As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads.

What you'll do

  • 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)

What they're looking for

  • Mentor and review work from mid-level and junior engineers
  • 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
