For over 10 years, Zscaler has been disrupting and transforming the security industry. Our 100% purpose-built cloud platform delivers the entire gateway security stack as a service through 150 global data centers to securely connect users to their applications, regardless of device, location, or network in over 185 countries protecting over 3,500 companies and 100 Million threats detected a day.

We work in a fast-paced, dynamic, and make it happen culture. Our people are some of the brightest and passionate in the industry that thrives on being the first to solve problems.  We are always looking to hire highly passionate, collaborative, and humble people that want to make a difference.

Zscaler’s Emerging Technology team is working on revolutionary new products including Zscaler Private Access (ZPA). This is an excellent opportunity to join a small, dynamic team that is charting new ground in cloud security technology. 

As a Principal Engineer, you will work on building the next generation distributed product. The Zscaler Private Access (ZPA) service enables organizations to provide access to internal applications and services while ensuring the security of their networks. ZPA is an easier to deploy, more cost-effective, and more secure alternative to VPNs. Unlike VPNs, which require users to connect to your network to access your enterprise applications, ZPA allows you to give users policy-based secure access only to the internal apps they need to get their work done. With ZPA, application access does not require network access.

As a Principal Engineer, you will play a crucial role in leading the innovation for the team, across companies for technology evaluation, integration as well as introducing disruptive technologies.  You should be able to work on designing, creating, and enhancing multi-tenant systems and deliver at a quick pace, while leading and directing a small team or own a BIG area and deliver independently without much supervision.
