Funny that you should ask. I went to the LinkedIn post, and there's a hyperlink there to the actual job listing on Microsoft's WWW site.
It is patently LLM-written. The 'Responsibilities' section shouts that fact the loudest.

Amusingly, for a job that deals in rewriting things in Rust, actual experience with that language is an optional requirement, whereas >= 6 years experience in Python or JavaScript fulfils the mandatory requirement.
Mind you, job listings have been autocompleted using boilerplate, especially by recruitment agencies, for decades.
