C Developer for Linux Kernel Team

[Virtuozzo](https://himalayas.app/companies/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 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. ### 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](https://himalayas.app/companies/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](https://himalayas.app/companies/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 * 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 Originally posted on [Himalayas](https://himalayas.app)
