Pay better. It's totally possible that you are paying appropriately, but I've been disappointed with my most recent job search and am likely winding up doing backend work again simply because those roles pay almost double.
I almost tripled my salary by moving from what the person your replied to is looking for to the web. AND it's easier. AND I can work remotely.
I don't blame them. But they'll be more and more desperate to attract people. The democratization of remote web jobs after COVID is another nail in the coffin. They pay less, 99% of the time you have to be in office. It's a losing battle.
Doubtful. If anyone is having a hell of a time finding electrical engineers or embedded developers, then by definition that means the field isn't lucrative enough for people to stay in it. That's exactly the case I've seen repeated in every post in this thread.
