I'm not sure who maintains the whoishiring bot, but the corresponding HN thread (https://news.ycombinator.com/item?id=9812245) has one difference: the header includes "When remote work is not an option, please include ONSITE." Perhaps this should be added to future "who is hiring" posts. It resolves the ambiguity between positions that are onsite and positions where the poster forgot to mention onsite vs. remote.
