Have you always been curious about how things actually work? Are you interested in compute infrastructure beyond just using someone else's cloud?

This is a rare opportunity to join a team that owns its infrastructure end-to-end: physical servers wired to hundreds of Gbps of Internet capacity, our own IPv4 space that we advertise ourselves, and a private cloud running across multiple locations. On top of that, we run a hybrid of Linux and macOS, a state-of-the-art scheduling system, and seamless orchestration across both our own and 3rd party clouds. We have it all.

You'll work across the entire stack — from redundant, multi-homed wholesale internet transit and data center-grade networking, to servers we source directly from manufacturers, right down to fine-tuning hardware, software, the OS, the hypervisor, and the scheduler. If the thought of LEDs and the smell of amps excites you, if you love nerding out on graphs, spotting patterns end-to-end, and continuously improving systems — then you'll have a blast here.
