Pretty sweet. Are all these entries posted by companies themselves or did you do the posting? I love how it's neatly organised by language. Are you planning on adding any other layers/filters? Edit - Why isn't this in Show HN?
Updated to be in Show HN :) - thx Yes I'm planning to add City/Location filters as well as advanced search option where you can see all available filters. There is for example also https://startupdeveloperjobs.com/f/0/Erlang but you can't see it since it has not enough jobs Edit: To answer your other question. Jobs are both entered by companies and also added by me manually.
Location filters are must-have - whether it's just a sort by name so all of the $MY_CITY jobs are in one place, as a true filter so I only see one location or as some kind of location-based sort-by-distance to give me the best options first.
Congrats on shipping!
