Thank you. I already watched the presentation, but couldn't find any open job positions in regards to Racket. I'll try to contact them directly and will see if I have some luck.

I think they may have stopped that after being bought by Sony? I don't think it is still around.

I think they still use it for scripting in their games. For things like AI, etc.

They are using an in-house variant of Scheme known as DC. There are a few pages about it in Game Engine Architecture, a book written by an engineer at Naughty Dog. https://www.gameenginebook.com/

DC is compiled to bytecode then interpreted. DC compiler is written in Racket.
