C developer for Linux Kernel team

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 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 • 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
