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 the integration between our endpoint sensor and browser extension technology. You will own the end-to-end quality process for how the sensor and browser extension work together to deliver data protection — from hands-on exploratory testing and test strategy design through to building robust automation. As a key contributor to the team, you will drive validation for new capabilities, ensuring data protection works as expected across the full stack. Working closely with sensor, cloud, and extension development teams, you'll coordinate testing efforts, participate in technical design discussions, and lead code reviews. We're seeking a senior engineer who works independently, thrives on technical challenges, takes full ownership of quality for their domain, and contributes to a culture where quality is paramount.
