I was lucky enough to land a Clojure job (stitchdata.com, we're hiring!) before having to learn Clojure, because I had the benefit of experienced mentors helping me get to grips with lisps (which were alien to me) and a development workflow that leaned heavily on the REPL (emacs + cider). Clojure has changed the way I think about many programming concepts and has been a joy to learn. It has it's warts but the core is very well built and I find the documentation to be quite good once you understand the basics.
