What is a Data Scientist at Zscaler?
As a Data Scientist at Zscaler, you will operate at the intersection of massive-scale cloud security and advanced machine learning. Zscaler runs the world’s largest security cloud, processing over 400 billion transactions per day to protect global enterprises from cyber threats. In this role, you are not just building standard predictive models; you are developing the intelligent engine that identifies and thwarts sophisticated cyberattacks, zero-day vulnerabilities, and anomalous user behaviors in real time.
The impact of your work is immediate and immense. By leveraging telemetry from millions of global users, you will design, deploy, and scale machine learning models that run inline within the Zscaler Zero Trust Exchange. Your algorithms will directly power threat detection pipelines, automate security policy enforcement, and optimize network traffic routing, making the digital world safer for thousands of organizations.
This position requires a unique blend of deep theoretical machine learning knowledge, robust software engineering skills, and a product-oriented mindset. Working with petabyte-scale data, you will collaborate closely with security researchers, platform engineers, and product managers to turn complex security telemetry into actionable, high-performance ML models. It is a highly demanding but exceptionally rewarding role where your code and models directly defend the global digital infrastructure.
