Senior MacOS QA Engineer
Job Overview
As a Senior macOS QA Engineer, you will play a critical role in validating the stability, security, and compatibility of the company's technology for macOS. This is a deeply technical manual QA role requiring hands-on experience with macOS internals, system extensions, and application behavior.
What You Will Do:
- Test macOS security features that span across system extensions, Endpoint Security, and Network Extension frameworks.
- Design and execute manual test plans for system extensions, inter-process communications (XPC), and low-level OS 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/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 company and third-party macOS apps and services.
- Collaborate with SDETs to turn exploratory and regression cases into automation candidates.
- Maintain deep familiarity with changes in macOS releases and how they might impact functionality and compatibility.
Requirements
- 5+ years in QA for macOS applications, with a focus on security, system-level, or compatibility testing.
- Strong understanding of macOS internals: System Extensions, Endpoint Security, XPC, TCC, SIP, Launch Services, file systems, etc.
- Familiarity with macOS diagnostic and monitoring tools (e.g., Console, Activity Monitor, Instruments, fs_usage, dtrace, tcpdump, lldb).
- Experience testing low-level products (VPNs, endpoint security, antivirus, etc.).
- Ability to read crash reports, debug logs, and identify root causes.
- Ability to work independently and deeply investigate issues before escalating.
- Excellent written communication for clear test case documentation and bug reports.
