The page you linked is filled with violations. There is no universe where an “AI scientist” shouldn’t be making the median salary at a minimum. The job titles have been manipulated so as to not raise any flags.

It doesn’t matter whether the median in aggregate is inside the range. If one person makes 60k, another makes 150k and another makes 155k you are still not paying someone enough. No American was going to take that job for 60k, that doesn’t mean you can use a visa to fill it.
