Why we read it this way (7)
The role is deeply framework- and infrastructure-building focused (designing automation platforms, CI/CD pipelines, performance testing systems), which creates genuine ambiguity between 15-1253 (QA/Test) and 15-1252 (Software Developers). 15-1253 was chosen because the primary mission is explicitly QA-first validation, but the runner-up is noted.
The programming language requirement lists Ruby, Java, C#/.NET, C++, Perl, and Python as interchangeable options; one skill entry captures this with alternatives. Similarly, the automation framework requirement lists JUnit, TestNG, PyTest, RSpec, Selenium, and Cucumber as equivalents.
The degree requirement states 'Bachelor's or Master's degree … or equivalent experience', so no minimum degree is hard-gated.
The experience range is 4–7 years; 4 is used as the minimum.
