I guess with a benign modification it does work: it’s just dual licensed (a)gpl and commercial license, the latter available when offered a job. The former always available but of course they’d have to release their entire stack’s source, which Anthropic almost certainly wouldn’t want to do. That’s not OP’s fault though and the license stands as pure (a)gpl.
It would be very, very hard to make this work in practice.
What does it mean to offer a job? Can they offer a job that pays a dollar a year and call it a day? Or can you force them to offer you a job that pays a billion dollars a year?
Can they offer you a job, but only in Antarctica? What about visa sponsorship?
Of course, you can write whatever ill conceived terms you want in your license. But if your license is badly written, any decent company lawyer would strongly advice staying away from your code. And if that's the outcome you want: you might as well open source it with a 'non-commercial use only' license.

Well, it's similar to having a license that allows the author to decide on the price of the product after the other side has decided to buy it. There just won't be any buyers.
> Hah. Well it is now...just copy & paste the GPL's text and append that one condition.
Section 7 of the GPL (version 3) explicitly gives the user the right to remove that additional condition. So if you want it to be effective, you will at the least need to remove section 7 from your copied GPL. Then, you'll need to remove the preamble and instructions to avoid the Free Software Foundation's ire (they're being generous in allowing you to modify the license test at all).
Ultimately, it goes against the spirit of the GPL so much (and against the point of FOSS in general) that it would be entirely unjustifiable to use the GPL as the foundation for such a proprietary, source-available licence.
The FSF holds the copyright to the text of the GPL, and they allow anyone to freely redistribute verbatim copies, but they don't permit just anyone to create derivatives.
