I guess they are open to both on-site and remote positions. Also interns. And will sponsor Visas. That's the only interpretation that makes sense to me.

... you could also try entering that in Scribblenauts to see what sort of creature comes up.

From the main post:

> include the keywords REMOTE, INTERNS and/or VISA when the corresponding sort of candidate is welcome.

At first I thought these were all separate tags for the listing, but I checked out their (surprisingly complicated) careers page, and I honestly can't figure it out. OP, can you help us out? Are any positions available for remote work?
