О компании и продукте

• Virtuozzo isn’t just another virtualization company — we’re the original architects behind Linux namespaces and c groups .
• We helped shape container technology well before it became the norm . From kernel-space to userspace, 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.

Задачи

• 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

Требования

• 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

Будет плюсом

• 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

Условия

• Flexible hours and remote work options
• We help our team get private medical insurance
• Employee recognition programs and reward systems
• 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 may apply
