You need to be more specific. Are you in engineering role? Its very usual for both husband and wife to work, if you want a home in good school district and nice commute. It can get a little hectic at times. Leaving at 3-4 everyday may be tough but one of you can do 3 days a week and the other 2 days a week. Else, with two salaries, you can hire a part time nanny and ask her/him to bring kids from school. That way, stress levels are manageable.
I don't work in FANG but have a similar lifestyle. Since the money is good, I would suggest you take the offer.
