What kind of tech? Lots of it gets contracted out, there's not that much full time staff at any given facility.

I used to travel installing Optical Networking equipment, there's definitely demand there but it's brutal travel.

You could look into the big 3rd party providers Equinix, Digital Realty, etc, they often have some openings. The main thing to consider is they have some pretty crazy shift schedules. Lots of them 12 hours 3-4 days a week with nights etc.
