The job market is smaller, but so is the pool of developers. Companies tend to be more flexible because of that and are often open to remote work. I'd much rather work in a sane niche market than deal with the mainstream churn.
We have local Clojure meetup in town, and when I first started going there pretty much everybody was using Clojure as a hobby. Today, we have a bunch of companies using it in production, and all of them are actively hiring. The last three coop students I had all ended up getting Clojure jobs. I imagine this varies based on where you live of course, but another option is to simply introduce Clojure at a place that's using something else. That's where Clojure jobs come from in the first place at the end of the day.
