Software Development Engineer in Test (MacOS)

We're looking for a deeply technical and hands-on Software Development Engineer in Test (macOS) to own the quality of their macOS integration layers — including endpoint security agents, network extensions, and other system-level components. You'll work closely with engineering and product teams to build high-fidelity automated tests, validate complex behavior across macOS internals, and ensure our platform’s reliability, security, and compatibility on Apple hardware. This is not just UI testing, but a comprehensive approach that requires in-depth knowledge of macOS architecture, frameworks, and APIs. As part of this role, you will be responsible for designing, developing, and maintaining automated tests using various tools such as Appium, Selenium, or other relevant technologies. You will also collaborate with cross-functional teams to identify and prioritize testing needs, develop test plans, and execute tests to ensure the quality of our software products. In addition, you will work closely with the engineering team to troubleshoot issues, debug code, and optimize performance. This role requires a strong understanding of software development principles, testing methodologies, and macOS-specific technologies. If you have experience in software development, testing, or related fields, and are passionate about delivering high-quality products, we encourage you to apply for this exciting opportunity.
