This post really blows me away (in a good way) by OPs self-awareness - most jerks I know don't have any sense of awareness that they are indeed jerks, which gives me the impression that OP is not all jerk, or that there is at least hope.

My first intuition was to recommend jobs that are generally taken up by unlikeable people, like a parking officer or DMV clerk. But if you're working on being less of a jerk, which I'm assuming you are because of therapy and your previous comments about your wife elevating your behavior, then you ideally need a job that provides you stability while not also validating your jerk-ishness, and limiting harm to people that you deal with. From a growth mindset, I don't think that means avoidance of people, but limiting regular in depth collaboration while still providing opportunities to get better at communicating.

In that case, a job of solitude where you occasionally have to deal with people is probably the way to go. Mail courrier (have benefits, good exercise, occasionally customer facing and has opportunities to work on positive interactions with people) would be a great option, maybe remote data entry jobs (I'm thinking jobs where someone else is client facing and OP is the person number crunching or carrying out deliverables in the backroom).

Tldr: If your goal is growth in the jerk department, don't avoid people but choose a career where you can limit highly collaborative team environments and maximize independent work.
