And since we’re a small company, our engineers get more end-to-end responsibility, and have bigger, individual impact. Sound like you?

Hey, we developed QFS! (Quantcast File System)

Working with big data isn’t easy — or cheap. Big data typically demands massive amounts of storage and computing, electricity and space to run and cool all the hardware, plus ample staffing and resources. As any organisation that works with large data clusters in production can tell you, the associated costs can multiply quickly, making efficiency paramount.
