I've heard a lot about commissioning jobs for data centers being in demand, and I'm pretty bored at my current job, but I don't know what/if companies specialize in that. A google search brings up a ton of options and I'm not sure what are the reputable companies. Is a field engineer at a GC the same thing, or do the smaller contractors specifically have commissioning engineers for their systems?

Anybody in that industry know what companies I should look at, or where I should start? Thanks! (USA)
