What job postings? They need literally DOZENS and DOZENS of toolmakers, machinists, CNC operators etc... Point me to the 200-300 job listings that would be required to assemble a crew in Lathrop for the task of building Model 3 die sets (because we know it can't be for Model X). That's not even mentioning that those people do not exist in California, so the large majority would have to be recruited and relocated. That takes time and if I look at the calendar we're running out of time to do something of this scale. I'm not sure you understand the scope and size of a department that would be required to make hundreds of dies for the Model 3 and how long that would take to assemble and organize. And that's not even considering how much that particular industry has been decimated over the last couple of decades in North America. Nobody (in any large quantity) has gone to school to be a machinist or toolmaker for the last 20+ years.
Yes, I believe I've also heard that they want to build their own dies. So far, there's been no indication that I've seen that they're prepping for that. This is all I found listed for Lathrop:

So far all it suggests is a few more bodies for castings, although one position is for a recruiter. I'd hope they wouldn't leave the recruiting for Lathrop to do what you think they are doing to just one person, that alone would require a good sized team of recruiters.
