Sorry, not hiring currently but rest assured I've bookmarked this comment and will reach out when we do.

I'm an IC and have three more engineers working alongside, so a very small team.

We don't expect anyone we're hiring to know, understand or have even heard of Lisp :-), just the curiosity and willingness (which we evaluated in the interviews) to grok it when provided enough support and runway to get upto speed.

As you seem to be keen for such a job, the best bet right now is start using SBCL in your daily work. Trick: don't say you're using Lisp just show (the output), don't tell!
