About Netskope

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. 

Since 2012, we have built the market-leading cloud security company and an award-winning culture powered by hundreds of employees spread across offices in Santa Clara, St. Louis, Bangalore, London, Paris, Melbourne, Taipei, and Tokyo. Our core values are openness, honesty, and transparency, and we purposely developed our open desk layouts and large meeting spaces to support and promote partnerships, collaboration, and teamwork. From catered lunches and office celebrations to employee recognition events and social professional groups such as the Awesome Women of Netskope (AWON), we strive to keep work fun, supportive and interactive.  Visit us at Netskope Careers.

About the Role

We are looking for a Staff SDET Engineer to join our Cloud Firewall engineering team, responsible for validating large-scale cloud-delivered firewall services operating across globally distributed infrastructure.

The Cloud Firewall platform processes enterprise network traffic across multiple protocols and services, providing capabilities such as L3–L7 policy enforcement, traffic classification, DNS security, DLP inspection, service chaining, and microservice-based traffic processing across global points of presence.

This role is ideal for engineers who enjoy working on deep networking problems, distributed systems validation, large-scale traffic testing, and automation-driven quality engineering.

As a Staff engineer, you will help define how complex security services are validated, scaled, and operated reliably in production environments.

What You Will Do

System Validation and Test Strategy

• Design and execute test strategies for Cloud Firewall services and traffic inspection pipelines
• Perform end-to-end validation across multi-node and multi-region deployments
• Validate L3–L7 policy enforcement across different protocols and enterprise traffic patterns
• Verify correctness of policy evaluation, rule processing, and security service chaining workflows
• Ensure high availability, failover, and resiliency across distributed deployments

Traffic Processing and Platform Validation

• Validate traffic classification, session management, and packet processing workflows across Cloud Firewall services
• Ensure correct handling of multi-protocol enterprise traffic flows and application identification
• Validate interactions across microservice-based dataplane processing pipelines

Automation and Testing Frameworks

• Build and evolve automation frameworks for functional, regression, and system-level testing
• Develop automated validation suites using Python
• Integrate automated validation with CI/CD and release pipelines
• Develop tooling to simulate real-world enterprise traffic patterns and system failure scenarios

Scale and Performance Validation

• Design and execute large-scale traffic testing across distributed firewall deployments
• Simulate enterprise workloads across globally distributed POP environments
• Measure and analyze throughput, latency, connection scale, and system resource utilization
• Identify performance bottlenecks and collaborate with engineering teams to improve system performance

Debugging and System Diagnostics

• Perform deep debugging using tcpdump, Wireshark, logs, metrics, and packet captures
• Investigate complex issues involving traffic processing, policy enforcement, and microservice interactions
• Participate in root cause analysis for production incidents and customer escalations

AI-Driven Testing

• Apply AI-assisted testing techniques to improve coverage and defect detection
• Use AI for intelligent traffic simulation, anomaly detection, and automated analysis of system telemetry
• Improve debugging and test efficiency through AI-driven diagnostics

Staff-Level Responsibilities

• Define and influence the validation architecture and quality strategy for major
