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.
Data centers don't need very many employees once they are built, many have less than 20 employees.
This is a big part of the reason why they are such a bad long term deal for localities and why giving them tax breaks, etc is just a scam. They add a lot more negative externalities than they help with the local economy.

How many of these would have to get destroyed for them to go out of business?
Also easily found potential military targets: power generation, water treatment, hospitals, schools, government buildings, etc.
Odds of data centers being physically attacked at scale are low. Most of the population doesn't care enough, and the vocal minority is under a lot of scrutiny.
You can hide a handful of racks for some boring 2000s hosting. You can't hide a GW-scale AI behemoth.
Transparency is good.
If the US ends up in a similar asymmetric warfare scenario, the location of corporate data centers being known is low on the priority list. Google is assuming a peacetime footing where public transparency and accountability matter.
