We are seeking people that want to make an impact on the world’s leading communication networks and are experienced in networking architecture or AI infrastructure solutions. The Role We’re looking for a strong software engineer who can own complex problems, turn them into crisp technical requirements, and deliver robust solutions within our distributed system. You will join a team that owns the host layer between applications and hardware, including Linux kernel/OS integration, Docker engine, system security hardening and features, and other foundational infrastructure. The work is hands-on, performance- and reliability-critical, and involves investigating and researching complex flows across the stack (hardware, kernel, userspace, containers). What success looks like You deliver changes that are secure, observable, and maintainable. You collaborate with application teams and hardware/firmware engineers to unblock system-level issues. You can explain tradeoffs (performance vs. safety vs. complexity) and defend design decisions. Requirements Must Strong Linux proficiency - scheduler, namespaces, cgroups, permissions & capabilities, networking, eBPF. Ability to work with ambiguity and drive independent research - tracing behavior, reading source code, kernel docs. 5+ years of hands-on experience in production-grade development. At least one of the following: Hands-on experience with Linux internals - syscalls, ioctls, netlink, procfs/sysfs. OS/Kernel development or kernel-adjacent development - drivers, kernel modules, patches. Deep container experience - Docker, containerd, overlayfs, build flow, networking, hardening, seccomp/AppArmor/SELinux. Advantages Security-oriented experience - hardening, threat modeling, vulnerability response, secure defaults. Performance profiling & tuning - perf, valgrind, ftrace, eBPF. Real-time systems experience. Build and packaging systems. Distributed systems understanding - HA, failover, concurrency, consistency, observability. C/Python coding experience.
