Ask HN: Advice on breaking into embedded programming?

I have ~20 years of various application programming experience, from desktop, to web, to mobile. I'm primarily a game programmer, and have done optimization work on fairly high-profile mobile games. I'm good at asm, C, optimization, logic, and all things low-level.

For whatever it's worth (?) all my Shenzhen I/O scores are all the way to the left :)

I'm open to relocating anywhere in the U.S. Any advice on how to approach this would be appreciated.
