All the more reason for you to skip on over to this side of the pond, you wanker. Seriously. With your experience and accent you could get yourself set up quite nicely. You have a background involving logistics, so look at positions with the backend of trucking companies; something you probably never thought about but would be darn solid . In my rough geographical area a couple of larger players would be US Xpress and Covenant Transport, both located in or near Chattanooga (AKA Gig City).
He has devops experience too if I remember correctly. Combine the two, easily 6 figure salary over here.
I would earn significantly more in the US no doubt, but I would also be paying significantly more for healthcare and that kind of thing. I did look at how to get to the US a few years back, and it seems very difficult, apparently they changed the employment rules so US companies can only sponsor foreign workers to come to the US if they can demonstrate there is a lack of skilled people to fill the position within the US. Not sure how true that is in reality.
Though I guess I would remain a UK citizen so if I did need any expensive healthcare I could always jump on a plane back to the UK...
