I think there would be some swe that would occasionally need to go to timber mills, mines, sea ports, air ports, oil rigs , farms etc… prob to install or troubleshoot critical systems. I doubt it would be often though.
If you really want to be outdoors, that would be my recommendation - skill up as a licensed engineer.
For really remote mines (fly in fly out) an infra guy would go install the network and weighbridge systems with the swe on the phone or via email for any issues, but then he wouldn’t go out there again unless there was catastrophe - everything was managed remotely.
I’m sure there’s other companies or industries that may do it differently though.
