C developer - Linux Kernel
Virtuozzo isn’t just another virtualization company — we’re the original architects behind Linux namespaces and cgroups.
We helped shape container technology well before it became the norm. From kernel-space to user-space, we're deep into the Linux operating system — optimizing it to scale and isolate like a boss.
Now, we’re looking for a C developer to join our kernel team. You’ll help push the limits of what Linux can do in large-scale virtual environments — and have fun doing it with people who love their jobs.
What You'll Do
Work on core Linux kernel subsystems — including memory management, scheduling, networking, and filesystems.
Tweak and tune container isolation mechanisms until they’repractically airtight.
Help Linux scale harder, faster, stronger.
Optimize resource usage across thousands of virtual machines and containers.
Collaborate with upstream maintainers to merge your patches into the kernel.
Representing Virtuozzo at professional conferences, such as Open Source Summit, FOSDEM, and other Linux Foundation events.
What You Bring
Strong C programming skills — the closer to the metal, the better.
Know your way around at least one kernel subsystem.
Comfortable with syscalls, kernel/user-space interfaces, and how Linux works under the hood.
Debugging experience using kprobes, ftrace, perf, gdb, or whatever else helps squash the bug.
We are a global remote team: You can communicate your ideas clearly in English, whether it's in a code review or a conference talk.
Nice to have
Past work on open-source projects (got a GitHub or a LKML link? We’d love to see it).
Deep knowledge of namespaces, cgroups, or KVM.
Python scripting for tooling, automation, or test harnesses.
Familiarity with DevOps pipelines involving container tech or kernel builds.
Why Virtuozzo?
Because we don’t just use Linux. We shape it.
You’ll be joining a team of low-level hackers and systems engineers who are obsessed with performance, isolation, and making Linux better for everyone. We care about clean code, smart design, and upstream-first principles.
If this matches with your idea of a productive day — let’s talk.
What We Offer
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 decisions from day one
A smart, friendly team that values reliability, simplicity, and automation
Depending on your location and preferred employment method, other perks and benefits apply
