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.

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.
