I actually don't. I haven't checked in a while, but just looked and my position is just listed as Principal Software Eng. I have no posts, nor any job details. In Skills section I have Linux, Go, Golang, among a few other things, with endorsements.

I think recruiters are perhaps able to scrape skills for keywords? I don't want my identity tied to HN, but if you drop me your email(or add it to your profile) i'll make a throwaway to reach out if you want.
