<p>all I know is you can work at JPL haha.
I’m sure there are a lot of private companies who also hire those people for R&D. I know there’s more though…</p>
<p>If you do ME you can be an engineer (obviously), and if you major in math/physics, you pretty much need to get a PhD or go to a professional grad school (engineering grad school, med, law, etc) unless you want to teach high school, and after that you can either teach or do research for the government or private industry.</p>
