I think you can't ignore the side issue that even if you work in a US tech company with better than typical female representation almost all the female engineers are immigrants who come from other cultures that have stronger emphasis on academic achievement. Saying you got to 40% women is not quite the same thing if 95% of the female engineers on the team immigrated from India, Russia, China, South Korea, etc.. You got yourself a decently diverse team but it doesn't hide the fact that US culture + education system has a major issue with discouraging women growing up in the US from entering some of these fields.
