I spent the majority of my career as an embedded dev. There are ... different ... challenges, and I'm not so sure that I would want to go back to it.
It pays poorly, the tooling more often than not sucks (more than once I've had to do some sort of stub for an out-of-date gcc), observability is non-existent unless you're looking at a device on your desk, in which case your observability tool is an oscilloscope (or bus pirate type of device, if you're lucky in having the lower layers completely free of bugs).
The datasheets/application notes are almost always incomplete, with errata (in a different document) telling you "Yeah, that application note is wrong, don't do that".
The required math background can be strict as well: R/F, analog ... basically anything interesting you want to do requires a solid grounding in undergrad maths.
I went independent about 2 years ago. You know what pays better and has less work? Line of business applications. I've delivered maybe two handfuls of LoB applications but only one embedded system, and my experience with doing that as a contractor is that I won't take an embedded contract anymore unless it's a client I've already done work for, or if the client is willing to pay 75% upfront, and they agree to a special hourly rate that takes into account my need for maintaining all my own equipment.
