I know this is anecdotal but…a very close female friend of mine who is an engineer worked part-time for years . Another female engineer friend works from home and a third also worked part time. All of these women have kids.
H is an engineer and has worked in government contracting for 30 years. He has worked with several female engineers and the jobs have always had some flexibility. His current boss (who he says is terrific) is a woman with 2 small children.
Based on the above I would not necessarily rule out engineering as a career if I were a young woman.
