Field engineer for a cellphone/mobile broadband company. You'll need to travel around to mast sites and customer sites to do QA, troubleshooting, test signal strength and do basic IP networking stuff.
This isn't far from where I live - I'd quite like to get into the engineering and particularly transmission side of radio (currently in programming although I have an amateur radio licence) but I don't fancy working 1,000 feet above the ground in a little cage... (look at the pics, they are stunning!)
You need a head for heights.
