Engineering San Jose, California


Position: Senior Big Data Administrator

Location: San Jose, CA

Zscaler enables the world’s leading organizations to securely transform their networks and applications for a mobile and cloud-first world. Applications have moved from the data center to the cloud and users are connecting to their workloads from everywhere, but security has remained anchored to the data center. Zscaler is redefining security by moving it out of the data center and into the cloud.

The Zscaler Cloud Security Platform uses software-defined business policies, not appliances, to securely connect the right user to the right application, regardless of device, location, or network. Zscaler offers two service suites. Zscaler Internet Access™ scans every byte of traffic to ensure that nothing bad comes in and nothing good leaks out. Zscaler Private Access™ offers authorized users secure and fast access to internal applications hosted in the data center or public clouds—without a VPN.

Zscaler services are 100% cloud delivered and offer the simplicity, enhanced security, and improved user experience that traditional appliances or hybrid solutions are unable to match. Used in more than 185 countries, the Zscaler multi-tenant, distributed security cloud protects thousands of customers from cyberattacks and data loss, enabling customers to embrace the agility, speed, and cost containment of the cloud securely.
