I work in a very similar field now. We just have aot more strict contamination, and insulation needs.
The company I'm looking into does a lot of ice rinks. They also do food facilities. They are a big outfit.
My pay now is stagnant, and advancement is nil. Just how it is where I work. My field is narrow, but directly related. I love my job and what I do, but they will NOT promote you and our budget has been slashed. We have not seen anything more than a 1.5% raise. Ever. 2 of the last 4 years, zero raise and I took an 850.00 cut this year due to a lost benefit. I get more time off here, however and it's probably more laid back.
I'm 43 and not getting younger. I'm interested in it being an employees market in this field.
They're taking 36 or so bucks an hour to start, possibly paying up to 45 after several years. I'll never see that where I am now, even though it's a lot more technical.
I get the feeling that the job is harder and dirtier than what I do now, but very similar. I work on a lot of similar equipment in cryo, the systems are just colder and must be kept cleaner.
Wife does not want me on the road overnighy all the time. Some or half is OK. All the time, probably not.
