If there's one thing I love about itch.io, it's how they really do work to help game developers in as many ways as they can and they're now launching a job listing board.
It's not enough that they: host game jams; have an open source client (that you're not forced to use); allow developers to give back nothing and take the full cut of sales; support Linux, Mac and Windows; allow developers to do a PWYW system instead of a set price; deal with VAT MOSS for you and the list goes on for a while.
Having a dedicated section for developers to post their developer job advertisements seems like a pretty fitting addition to everything else they do and there's even jobs already available from Failbetter Games.
What's interesting, is that this is going to be a little more curated. It's not a board for every single developer to post every tiny job they have going. It's for developers offering proper paid work that's either "paid full time or contractor positions".
