We build the underlying platform that supports hundreds of services and is used by over 400 globally distributed engineers.We're scaling into a cell-based architecture, and the number of cells we run is growing fast, taking our Kubernetes footprint from dozens of clusters toward hundreds. That takes the platform in three directions at once: infrastructure configuration becomes a first-class layer with its own lifecycle, independent of application code; provisioning a new cell becomes a days-long automated operation rather than a multi-week effort; and cross-cell control points become standard, reusable, and consistent everywhere.This is a Principal Engineer role with real breadth within the cloud platform.
