• As the Senior macOS QA Engineer, you will be responsible for validating the stability, security, and compatibility of a secure macOS platform used to protect sensitive systems. You will work alongside a team of engineers and reverse engineers to design and execute manual test plans that dig into system extensions, inter process communication, and low level operating system behavior. This is a hands-on, investigative role suited to someone who enjoys uncovering edge cases and understanding how complex systems truly work.

• • Test macOS security features spanning system extensions, Endpoint Security, and Network Extension frameworks
• • Design and execute manual test plans for system extensions, inter process communication, and low level operating system integration points.
• • Explore and document edge cases, race conditions, compatibility scenarios, and regressions across macOS versions.
• • Reproduce and isolate complex issues related to sandboxing, SIP and TCC interactions, launch services, and daemon behaviors.
• • Work directly with development, support, product, and automation teams to triage, verify, and regress bugs and compatibility issues.
• • Validate interactions between the platform and third party macOS apps and services.
• • Collaborate with SDETs to turn exploratory and regression cases into automation candidates.
• • Maintain close familiarity with changes in macOS releases and how they may impact functionality and compatibility.
• • 5+ years of QA experience with macOS applications, with a focus on security, system level, or compatibility testing.
• • Strong understanding of macOS internals, including System Extensions, Endpoint Security, XPC, TCC, SIP, Launch Services, and file systems.
