I was a ChE grad (now in semiconductor industry) and engineers a level up from me have opportunities to travel every so often to our sister sites in the US, Singapore, and Taiwan. A friend who was a ChE in industry had opportunities to go overseas as well. We also have 2-3 year expat opportunities in Singapore and Taiwan for a chosen few. It may not be weekly travel unless you are in sales or consulting but that may not be really what you want, at least not forever. It sounds especially alluring to hop on a plane every weekend even to me, but now that I'm married with a 3 month old daughter I'd hate to be away from them every weekend. Yes they can travel with you but at your own expense. My company did pay for me to travel - out to my new site when the old one closed down. Then back again, to sell our old house. Not especially glamorous .
