• Design & build new VirtIO drivers for emerging device classes
• Turbo-charge existing drivers — storage, networking, anything that moves bits
• Reverse-engineer Hyper-V paths to unlock enlightenments and squeeze every last cycle out of the hypervisor
• Own Windows logo & certification pipelines (WHQL, SVVP, etc.) so “it just installs and works.”
• Upstream & collaborate with open-source communities (VirtIO-Win, libguestfs, QEMU/KVM) — your patches help others

Share your wins at events that advance technology and creativity

• We need a kernel-level C engineer who lives and breathes Windows internals to help our VirtIO driver stack, adopt the best bits of Hyper-V (enlightenments, VMBus, etc.) and make virtualization on Windows fly
• Strong C programming skills and a knack for writing clean, maintainable, low-level code
• Command-line comfort on Unix/Linux — you’ll often test and script there
• Fluency with Windows kernel debugging (WinDbg, KD, ETW, or your secret sauce)
• Reverse-engineering chops — static/dynamic analysis doesn’t scare you
• Clear written & spoken English because we’re a fully remote, globally distributed team
• Track record in open-source (GitHub, mailing-list posts, patchsets)
• Familiarity with QEMU/KVM internals and how VirtIO works on the host side
• DevOps know-how: CI pipelines, driver-signing automation, artifact delivery
• Python scripting for build tooling, testing, or data crunching

A smart, friendly team that values reliability, simplicity, and automation

• Flexible hours and remote work options
• Share Options — everyone shares in our success with share options
• We help our team get private medical insurance
• Space for creativity and experimentation within the company’s goals
• Supportive, engineering-driven culture with minimal bureaucracy
• The chance to influence Core team and R&D decisions from day one
