About the Role:
Be part of the team developing Falcon Data Protection, which safeguards organizations' sensitive data through advanced data loss prevention capabilities integrated seamlessly into the Falcon platform. This innovative solution combines machine learning, policy enforcement, and real-time detection to protect against data breaches while maintaining endpoint performance and user productivity.
This is a Senior Software Development Engineer in Test (SDET) position on our Falcon Data Protection product development team, focusing on our browser extension technology for endpoint security. As a key contributor to the team, you will architect and implement end-to-end test automation for a browser extension that operates across multiple browser types, ensuring robust data protection directly within the browser. You'll own the testing strategy for the full extension lifecycle — from installation and policy enforcement to egress detection — while working closely with sensor and cloud teams to validate seamless integration across the entire stack. We're seeking a talented engineer who thrives on technical challenges, takes ownership of their work, and contributes to a culture where quality is paramount.

Work closely with a team of engineers to support and maintain a culture of high product quality and excellence
Design and implement comprehensive test strategies for the browser extension, covering installation, lifecycle management, content script behavior, background workers
Build and maintain E2E test automation using Playwright, validating data loss prevention capabilities across different browsers and platforms
Develop tests for extension-to-sensor communication, ensuring policies are correctly enforced end-to-end
Drive cross-browser testing, identifying and debugging browser-specific issues
Manage test infrastructure including CI/CD pipelines in Jenkins, ensuring fast and reliable feedback loops
Use MDM tools (Jamf, Intune) to deploy and validate enterprise extension distribution across Windows and macOS environments
Lead rigorous test and product code reviews with an eye towards improving reliability, security, and maintainability
Debug complex cross-platform issues found through testing or customer cases to identify root cause and enhance test coverage
Collaborate with product and release management to control risk, improve quality, and streamline release cycles

Understanding of process communication and error handling in system-level integrations
Demonstrated ability to:
Design and implement comprehensive test strategies
Lead test initiatives and mentor team members
Work effectively in a globally distributed team
Communicate technical concepts clearly to various audiences
Proven track record in product development and release cycles
