Can I post a job ad?
Please don't post job ads as submissions to HN.
A regular "Who Is Hiring?" thread appears on the first weekday of each month. Most job ads are welcome there. But only an account called whoishiring[1] is allowed to submit the thread itself. This prevents a race to post it first.
Another kind of job ad is reserved for YC-funded startups. These appear on the front page, but are not stories: they have no vote arrows, points, or comments. They begin part-way down, then fall steadily, and only one should be on the front page at a time.
