#C01932BJGE8 would be a good fit. In the
channel explanations the only mention of job posting is in announcements. But it does say to ask Ivan. (Those channels basically have the same number of people in them, so I don't think it really matters as far as reach goes).
You are more than welcome to post it imo. We try not to have drive by random job postings from people not connected with the community. But your work is definitely relevant here.
