Full description

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.

Responsibilities

  •   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.
  •   Familiarity with macOS diagnostic and monitoring tools such as Console, Activity Monitor, Instruments, fs_usage, dtrace, tcpdump, and lldb.
  •   Experience testing low level products such as VPNs, endpoint security tools, or antivirus software.
  •   Ability to read crash reports and debug logs and identify root causes.
  •   Ability to work independently and investigate issues thoroughly before escalating.
  •   Excellent written communication for clear test case documentation and bug reports.
  •   Compensation: $6,500 USD per month.
  •   PTO and Holidays
