I use to be a Sr. Network Engineer in 2000 for Amazon. I could only drink the Kool-Aid for about a year. Then went on to work with smaller companies and burned out on that. Worked almost 2 years installing DirecTV, I was 2 stone lighter on that job. Then ran around as a service tech fixing strip mall stores and big box stores... go tired of all the driving.
Now, at 53, I'm working for a medium size aerospace firm and learning MS. We got bought out by the French and will be switching to Zodiac and having to renumber the whole shop. I'm getting paid half of what I got at Amazon, but much better healthcare. I have a very short commute and love the people that I work with. My job title is SysAdmin, but really it's network engineering, facilities, plumbing, help desk, electrician, cable monkey, and AV club. I love the verity and am very happy.
Look for a smaller place where all the little things you've learned over the years come in handy.
