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’re
practically 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.
