[scruple]

I started my career in embedded at an RF company. Back then, I was 20 years junior to the next oldest guy and he was 20 years junior to the rest of the engineers. It was an incredible place to start, learning from some crusty old veterans who were pushing into retirement age. I ultimately left because the pay wasn't there. I've often thought I'd love to go back, even if it meant a decrease in pay, because the environment was so rich with learning and experimenting.

I also started in embedded development at a company where there was a significant RF component (essentially, we were doing wireless networking in 1986 - like wifi about 10 years early). All of the digital & software folks were youngish - 20s, 30s. But the RF guys were all in their 50s or older.
