Individualism isn't about the job you do. It's a philosophical conviction.
In modern society, the two often are conflated into one religion: an individualist philosophy being the "faith", an individualist job being the "works".
I think you can do a very "communitarian" job (working in a team, in a factory or in any other collective structure) and still hold pretty individualistic views. IMO, one's way of life isn't that much correlated with its conviction.
Indeed, I would say that you could hold to an individualistic world view & then choose tradition & community for reasons unrelated to a belief in any objective formulation of their merits. I've often thought about joining a church for the social experience, even though I am thoroughly atheist.
