> Initial steps included writing job descriptions that avoided masculine phrases like "Ninja rock star coder."

When my fellow male engineers see that in a job ad, they avoid it like the plague.

> Now that 17 of Gusto's 70 engineers are female.

After a focused campaign to hiring women, Gusto's results are nowhere near 50/50. And they had to go out of their way to hire women and focus resources to attracting women.

The male engineers at Gusto were no doubt happy to see diversity, especially since Gusto did not drop their standards just because an applicant is female.
