We, at Linki Tools [0], use Racket for our main product: S10 [1]. Not hiring at the moment but most likely will in the near future. I always hire remote (contracting up to now) and by the time I have to hire remote for racket I don't think I will have any problems finding a fine dev.
If you're in the Frankfurt area, I will be presenting at the first After Work Racket [2] on Thursday, the 8th. Come join us.
