We need engineers to design and build simple, robust infrastructure to manage all of it. You will design, build, evolve, and maintain systems like these:Routing and switching infrastructure: every component in the lab is on the network. Keeping thousands of heterogeneous devices provisioned, addressable, and reliable is a core engineering problem, not an afterthought.Job Scheduler: we run a diverse set of programs across a diverse set of machines, scheduled by a process manager we built ourselves.Data storage: every aspect of the lab is recorded (cameras, software logs, hardware telemetry, equipment output, research results) and stored in a time-series database.
