Be the force behind the world’s largest security cloud

Join Us

Engineering at Zscaler

The Zscaler engineering team has built the world’s largest cloud security platform from the ground up — and it just keeps building. With nearly 100 patents, and big plans for enhancing platform services and increasing its global foot- print, the team is taking the Zscaler multi-tenant architecture from innovative idea in 2008 to the cloud security leader in 2016, with more than 15 million users in 185 countries.

Join our team of cloud architects, software engineers, security experts, and many others whose vision and passion are fueling Zscaler and, in so doing, are enabling organizations around the world to harness the speed and agility enabled by a cloud-first strategy.

Security Research

ThreatLabZ is the security research arm of Zscaler. This world-class team is responsible for hunting new threats and ensuring that the 15 million users on the global Zscaler platform are always protected. In addition to malware research and behavioral analysis, team members are involved in the research and development of new prototype modules for advanced threat protection on the Zscaler platform, and regularly conduct internal security audits to ensure that Zscaler products and infrastructure meet security compliance standards. ThreatLabZ regularly publishes in-depth analyses of new and emerging threats on its portal, research.zscaler.com.

Emerging Technologies

Many organizations are just beginning to realize the amazing power and efficiencies enabled by the cloud. But our teams have been there for years, and our Emerging Technologies team has been at the forefront of cloud technology, developing innovative tools and systems that are giving customers better visibility and security than they’ve ever had. The cloud is transforming business, and the Emerging Technologies team offers a unique opportunity to shape the future of security in the cloud.

Cloud Operations

The Cloud Ops team is responsible for keeping the engines running at peak performance. On any given day, the Zscaler cloud processes 25 billion transactions — scanning a petabyte of data — for 15 million users around the world. The transaction volume on the Zscaler cloud is growing by 13 percent every quarter, yet the cloud’s overall stability just continues to improve, and that is directly attributable to the Cloud Ops team’s deep expertise and its dedication to reliability, availability, and scalability. To be a part of this team, you will, above all, need to share this dedication. And a sense of humor wouldn’t hurt.

Development

We develop innovative solutions that are transforming the Internet security business, and millions of users rely on our service for data protection and comprehensive security. We also provide real-time analytics to our customers for unmatched visibility, and maintain a state-of-the-art NOC. The development team works on web filtering, policy enforcement, next-gen firewall, sandboxing, DLP, and mobile user solutions. Being responsive to our customers and delivering industry-leading mission-critical solutions require precise engineering and a philosophy of continuous improvement, both areas in which Zscaler engineers excel.

Quality Assurance

Like any technology company, we rely on QA to ensure that our products perform exactly as promised. But as a company that provides technology services, based on our own purpose-built global cloud platform, QA has a singularly important role at Zscaler to identify potential customer pain-points ahead of time. Our customers — including some of the largest global organizations — send all their traffic across our platform, and that’s why QA is out in front at Zscaler, helping to ensure that our services work properly in the cloud and that our cloud, itself, is delivering on SLAs and providing the performance and reliability on which our customers depend.

It feels more like a big family than an office of people you happen to work with.
Gregg Baker, Cloud Operations Engineer

Every day I look forward to working with a wicked smart engineering team with unparalleled dedication, very engaged founders and passion for supporting our large set of marquee and growing customer base.
Bakshi Kohli, VP of Engineering

I know that there will be a new fulfilling, interesting technical challenge waiting for me. It's quite honestly difficult to be bored here.
Bill Fehring, Cloud Architect

What I found unique here is from the day one you are trusted with a part or at times a whole project which is of high value to the company. And they never doubt your abilities but always make you believe that you are the one who can handle it best.
Preeti Arora, Associate Software Engineer

Bugging the dev teams!!! On a serious note, it's my wish to be a part of something great.
