My mentor got laid off from Microsoft Research. Is there anything I can do to help him find a new job?

I am a grad student and I wanted to know if there was anything I could realistically do. I think he's the best supervisor I've ever had, and working with him was very fun, and made me grow a lot as a researcher. He's done a lot for my career and I think the world would be grossly unfair if he didn't get another research job.

I would love to serve as a reference but I don't think universities or industrial research labs listen to random grad students.
