Austal builds ships.
That job listing is for a diesel mechanic that specializes in the size engine used for ships. Engines used to run fracking pumps are probably the same size so I can see why they posted that in Austin. They probably have same ads in Houston, and Tulsa too.
Austel builds the LCS, and other ships.
It’s not for mechanic at all, if you go read it, it’s a very high level procurment job, mega-managing builds over and above normal production.
My only reason for posting that is you don’t see that kind of job posted in CL, in Austin anyways, again just a datapoint. Especially with zero trying to shut down our Naval Assets.
