Even though I love Clojure, my advice is not to restrict yourself to it. Adopt the polyglot mindset, and learn a mix of mainstream and niche language. You’ll be more versatile.
Now for Jobs, yes you can find one, but job hunting is more than language. Think about it holistically, the company culture, your interest in the mission or product, the opportunities for you to learn and grow, how much you jive with the city it’s in. etc.
Also, while it is not as fun, your mastery of programming languages doesn’t play that much into growing as a dev. Instead, you need to focus on building responsibility and influence. Being able to take business ideas and make them real, by refining requirements, gathering support, designing proper architecture, leading other devs, mentoring others, making the right choices, and being able to bring all that together to successfully build products or establish processes. That’s the true skills of a senior dev.
Mastering technology is important as well, but it takes the backseat most of the time, unless you specialize, like if you go in ML, Graphics, OS, sound, etc.
I’d also recommend if you relocate to go somewhere with options. Like a big city or tech hub, Austin, San Jose, San Fran, Seattle, New York, etc. It affords you to easily change job if you find yourself somewhere you don’t like much more easily, and generally just offers more opportunity.
P.S.: Do look for Clojure shops too, and you can try and prioritize them, just don’t make it your only dimension.
