Sr. Staff Software Development Engineer in Test, CASB Inline

Today, there's more data and users outside the enterprise than inside, causing the network perimeter as we know it to dissolve. We realized a new perimeter was needed, one that is built in the cloud and follows and protects data wherever it goes, so we started Netskope to redefine Cloud, Network and Data Security. 

In this role you will be a key member of our in-line CASB Inline product, which have been recognized by Gartner as market leaders in their Magic Quadrant reports: Netskope CASB in Gartner 2023 SSE Magic Quadrant
