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.

Build and maintain integration and end-to-end tests using Python, ensuring data protection features works correctly across sensor and browser extension on both Windows and macOS platforms
Review developer-written tests and SDET test code with an eye towards improving reliability, security, and maintainability
Debug cross-platform issues found through testing or customer-reported cases to identify root cause and enhance test coverage
Reproduce and validate fixes for customer-reported issues
Manage test infrastructure including CI/CD pipelines in Jenkins, ensuring fast and reliable feedback loops
Participate in SDLC ceremonies as part of major initiatives, collaborating with sensor, cloud, and extension teams
Collaborate with product and release management to control risk, improve quality, and streamline release cycles
