CAD CAM skills
The required skills you are quoting were ones I picked up along the way on a number of "Engineering" courses during '80s along with virtually every vocational electronics course up to degree requiring me to make yet another a plum bob, drill stand etc along with material science which was interesting but included with the rest because Electronic Engineers were more expensive for the uni to employ that other disciplines.
Technical drawing to drafting in autoCAD for my sister's company when I switched from electronics to computing but I still remember the tedious vocational lessons that included remembering the names of all the parts on machine shop kit for repair ordering along with the cutting angles and speeds that I haven't used since.
Like everything else the time served training I obtained has disappeared to be replaced by chancers teaching from a book/pilfered presentations also written by chancers.
I met a few of the people I took the courses with who had since lost limbs at work without compensation of any kind so you can imagine how many that went the same route as myself are willing to go back into the subject in the current working environment. I met up with a sheet metal MD who was complaining about lack of skilled people to employ but what he was really saying was that he was unwilling to either train or pay a reasonable rate for the skills.
I mention all this because there are others like me that have done different things since they learnt the skills you require, perhaps you are looking and advertising in the wrong place for your new staff.
