>FWIW, at a FAANG!

Do you work on ITA? Only FAANG I'm aware of using Lisp is Google.

Nope not on ITA. I work at the intersection of HW and SW. Lisp is valued for its strengths and I haven't come across any tool better to explore complex problem space. Of course, the opportunities are fewer, get filled up organically and are better suited for someone with valuable domain knowledge who can translate it into working space for a wider team using Lisp as the tool to write the spec!
