How can I find teams or small companies that need generalists?

Assuming that you're talking about being a generalist in SW, there are many companies (including the one I work for) that has job positions that just state "software engineer". This is sometimes an explicit choice that we are just trying to hire good people who are competent software developers.

In general I'd say this would work at places that are: a) Fairly small (dev team <30 people) b) Make a complicated product or deliverable (this usually means you have lots of moving pieces that need to work together)

I prefer to call the role "Variety Specialist"

Sometimes problem solving needs some understanding of a domain. Otherwise it becomes difficult to solve problems in the said domain. Two domains that immediately come to mind are Security and 3D games.

I am looking to team-up with a generalist for 3D XR simulation projects who will be comfortable with NDK and Godot.

Now when I say generalist, I mean generalist in the 3D graphics/Virtual Reality/games domain. Anyone who will struggle with graphics technology, low-level optimisation will find it hard to contribute to the project.

So generalist term should be combined with domain. Otherwise it does not have much meaning.
