First - Susan Wojcicki is not an engineer or a scientist. She is mostly a beneficiary on knowing a couple of geeks at the right time and place. 

It is a well established fact that men and women's brains are wired differently. I suspect the much higher rate of autism in men versus women (5 to 1) is a result of the same type of brain wiring that gives men an advantage in math. That doesn't mean women cannot be good mathematicians, but the odds are better a man will be than a woman. Instead of trying to pound square pegs into round holes lets just accept that men and women can and do have different areas of excellence. And there are exceptions to all rules.

As for women in tech companies - the track record for women as CEOs in tech is abysmal. Is that because they are not suited for the job or because the male culture sabotages them?
