<div>Windows Kernel Developer (C) &mdash; Bring VirtIO &amp; Hyper-V Enlightenments to Life 
Virtuozzo isn&rsquo;t just another virtualization company &mdash; we&rsquo;re the folks who pioneered the first commercially available container virtualization technology and developed Linux namespaces and cgroups. Today, we&rsquo;re 
pushing the envelope across platforms, investing deeply in Windows paravirtualization so our customers can run mixed-OS clouds with zero compromise on performance. 

That&rsquo;s where you come in. 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. 
What You&rsquo;ll Do 
<ul>
<li>Design &amp; build new VirtIO drivers for emerging device classes. 
</li>
</ul><ul><li>Turbo-charge existing drivers &mdash; storage, networking, anything that moves bits.</li>
</ul><ul><li>Reverse-engineer Hyper-V paths to unlock enlightenments and squeeze every last cycle out of the hypervisor. 
</li>
</ul><ul><li>Own Windows logo &amp; certification pipelines (WHQL, SVVP, etc.) so &ldquo;it just installs and works.&rdquo; 
</li>
</ul><ul><li>Upstream &amp; collaborate with open-source communities (VirtIO-Win, libguestfs, QEMU/KVM) &mdash; your patches help others. 
</li>
</ul><ul><li>Share your wins at events that advance technology and creativity.</li></ul> 


What You Bring 
<ul>
<li>Strong C programming skills and a knack for writing clean, maintainable, low-level code. 
</li>
</ul><ul><li>Solid grasp of at least one Windows kernel subsystem (networking or storage preferred). 
</li>
</ul><ul><li>Command-line comfort on Unix/Linux &mdash; you&rsquo;ll often test and script there. 
</li>
</ul><ul><li>Fluency with Windows kernel debugging (WinDbg, KD, ETW, or your secret sauce). 
</li>
</ul><ul><li>Reverse-engineering chops &mdash; static/dynamic analysis doesn&rsquo;t scare you. 
</li>
</ul><ul><li>Clear written &amp; spoken English because we&rsquo;re a fully remote, globally distributed team.</li></ul> 


Nice to Have 
<ul>
<li>Track record in open-source (GitHub, mailing-list posts, patchsets). 
</li>
</ul><ul><li>Familiarity with QEMU/KVM internals and how VirtIO works on the host side. 
</li>
</ul><ul><li>DevOps know-how: CI pipelines, driver-signing automation, artifact delivery. 
</li>
</ul><ul><li>Python scripting for build tooling, testing, or data crunching.</li></ul>

Because we don&rsquo;t just use virtualization &mdash; we advance it. You&rsquo;ll join a crew of low-level hackers obsessed with performance, correctness, and upstream-first collaboration. Your code will power production clouds, hosting providers, and enterprise data centers worldwide. 
What We Offer 
<ul>
<li>Flexible hours and remote work options 
</li>
</ul><ul><li>Share Options &mdash; everyone shares in our success with share options 
</li>
</ul><ul><li>We help our team get private medical insurance 
</li>
</ul><ul><li>Space for creativity and experimentation within the company&rsquo;s goals 
</li>
</ul><ul><li>Supportive, engineering-driven culture with minimal bureaucracy 
</li>
</ul><ul><li>The chance to influence Core team and R&amp;D decisions from day one 
</li>
</ul><ul><li>A smart, friendly team that values reliability, simplicity, and automation 
</li>
</ul><ul><li>Depending on your location and preferred employment method, other perks and benefits apply</li></ul> 
If kernel deep-dives, reverse-engineering challenges, and making Windows virtualization fast sound like your idea of a good time &mdash; let&rsquo;s talk.
