Sr. Engineer - Sensor SDET

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.

Location: Hybrid — Tel Aviv, Israel

Success in this role means:

• Owning the entire quality process for sensor and browser extension integration — from test strategy through hands-on testing to automation

• Driving validation of new capabilities end-to-end, including test design, hands-on testing, automation, environment setup, and coordination across teams

• Identifying what can and should be automated, and building that automation incrementally

• Reviewing developer test code and SDET test code to raise the quality bar across the team

• Collaborating both within and across teams as part of SDLC ceremonies and major initiatives

• Building elegant, robust, and reliable solutions for complex technical problems

What You'll Do:

• Own the quality process for sensor-browser extension integration — design and implement comprehensive test strategies, configure environments (VMs, CI/CD pipelines) and coordinate with developers and QA

• Perform hands-on exploratory and manual testing of new features, then identify automation opportunities and build integration and E2E test automation

• 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

What You'll Need:

• 7+ years of hands-on SDET/test automation development experience

• Computer science degree or equivalent experience

• Strong programming skills in Python

• Extensive experience with:

  • White-box & black-box testing techniques and code review

  • CI/CD frameworks and testing methodologies

• Experience testing across both Windows and macOS platforms

• Understanding of process communication and error handling in system-level integrations

• Self-driven and able to work independently with minimal supervision

• Demonstrated ability to:

  • Design, document 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

Bonus Points:

• Ability to read and understand C/C++ code

• Experience with TypeScript/JavaScript and browser automation frameworks (Playwright or similar)

• Experience testing browser extensions (Manifest V3 preferred)

• Prior experience working with low-level code, operating-system internals, components, APIs, or module development on any of our supported platforms (Windows, macOS, Linux)

• Security-focused testing mindset — experience with policy enforcement, blocking/ allowing operations, and data loss prevention scenarios

• Understanding of event-driven architecture and cloud-native technologies

• Experience developing 24/7 enterprise software, including CI, testing, debugging, performance tracing, release management, telemetry analysis, and issue handling
