Build infrastructure handling hundreds of billions of files and petabytes of data at Dropbox
Work on the backbone systems behind Dropbox's file metadata, storage, and analytics infrastructure at massive scale — metadata for hundreds of billions of files, hundreds of petabytes of data, millions of concurrent connections. This is a deep systems role (IC3-level) requiring real distributed-systems and OS-internals depth, with occasional on-call.
