We’re the team that makes Dropbox “just work.” Core Sync owns the Sync Engine that moves your files safely to the cloud and back to every device—quietly, quickly, and reliably. Nucleus, written in Rust, is a big reason Dropbox stands out, and we’re investing to make it better. Our mission: keep content seamlessly in sync and build new sync features fast and with confidence. You’ll help turn tricky concurrency and filesystem problems into “it just works” moments that millions rely on. If you like chasing down p99s, eliminating edge-case conflicts, and shipping improvements that millions feel but rarely notice, you’ll love working here.
