Part-time and/or remote if that works for you. Pretty good if you work remotely for junior/middle level job, while having senior skill set. Obviously you earn much less than you could, but you're playing on easy level.
Also, specialize in some narrow field. Instead of being Python dev, you can be writing plugins/scripts for Blender. Maybe machine learning. That's not narrow, but much less people can do basic ML in Python than webdev in Python.
Maybe screw the programming, just do animations in Blender. Just make sure you don't specialize in something proprietary and headed into dead-end (like Windows Phone).
Probably not common in the US, but you can always try to negotiate with your existing employer. Networking should help here too.
If you live in a place with low cost of living, freelancing must be the most straightforward way to land a part-time job eventually. Some (obviously small) companies just don't have enough work (and money) to hire full time. Some of them go to Upwork or Toptal. I'd like to know what are other ways for them to find talent (except job postings of course).
