I thought we had a job board on PI Square to help community members find PI professionals to fill positions. If we don't maybe we should.
To my knowledge I've never seen anything like that on PI Square although I have seen some customers cross-post open recs from their companies as forum posts. If you feel passionately about having something like that on PI Square I recommend you reach out to Jarita Sirois.
I think the PI Professionals group on LinkedIn is sometimes used this way.
Perhaps this is the place you were thinking of?
