The fact that xxEightyxx has found not one, but two companies willing to pay six figures for a functionally part-time employee is pretty mind-boggling.
If you want high chance of relaxed workloads, look for large corporations that exclusively contract with government out of a large budget. For example, the defense industry (e.g., the few companies designing and manufacturing planes, radars, avionics, communication equipment, guidance systems) is the biggest supplier of these type of roles that I know of. The pay in these roles is usually market competitive or better. At least from my experience, only about 20% of time or less is actually spent "working on something", much of which is sitting in irrelevant meetings. I would only recommend it if you are purely looking to collect an easy paycheck and you have a high tolerance for boredom, bureaucracy, internal politics and incompetence at all levels.
Post-covid remote work that much of government and contractors have moved to (permanently?) has likely also made it significantly easier to have multiple "full time" jobs. Management does not care about anything in this sector except that hard deadlines are met (the real deadlines, very rarely even gets close), soft deadlines are missed (used to justify "needing" more money), and nothing is completed too quickly (they want to give the illusion that hard work is being done).
There’s an entire internet subculture of people devoted to doing this. Check out r/overemployed. And there are far, far more people who do similar things entirely above board as consultants and contractors.
