It’s actually really hard if you approach this from a well-meaning perspective, because typically you’d still be selecting the jobs based on your normal (when having a single job) criteria.

The key is to turn the thing upside down and seek out the jobs you’d normally reject - shifty companies with lower pay, bad tooling, tons of bureaucracy, etc - basically a place where no sane developer would willingly apply. Then, you’ll be the smartest person in the room without having to do anything special and the extra bureaucracy can be either automated away or come in handy as an excuse when you fall behind, while the lower pay isn’t really a problem if you have 4 of them running concurrently.
