I'm super appreciative of my current role for this and other reasons. I'm the sole software developer on a team of 6 people in a mostly isolated corner of the code base. I'm getting a ton of experience making calls and collaborating with non-engineers, while still getting to be involved in some broader discussions.

A company of 20-50 programmers seems ideal to me now, with an overall company size of <300. I feel larger might require too much bueracracy and smaller might lose out on QoL and scale of work that can be accomplished.
