I think you should probably do that -- niche job boards seem to do well, (or, at least, I've convinced myself that that is the case). I should also mention you can do this with the developer job matching tool my friend and I are making:

https://polyfill.work

If you hit "onsite" as a developer or employer you'll only be matched with in-person employers/developers. It's very much a work in progress at the moment.
