Pros
Retrotech is a great place to work with high standards. They expect a lot out of people but are willing to give in return. The people are very friendly and many of them are friends outside of work as well. The travel can be rough but also rewarding in both financial and personal sense. You will work hard in the field but you will have a strong sense of accomplishment when it's done. It's also a great opportunity to get to know the industry and your customers. There isn't a lot of structure but that means you won't get bogged down in a lot of pointless documentation or busy work. The new facility is fantastic, with nice furnishings, a cafeteria, a game room with pool and foozeball and a PS4 and even volleyball courts.
Cons
There is some resistance to change and some of their work methods are way out of date. Some of this is changing but the old guard is scared of new things and not generally willing to learn. The pace can be unrelenting at times. They expect people to work fast without a lot of direction, projects are turned around quickly. This can be a positive if you have the right skills and attitude as well. Travel can mean long stretches away from family and friends, especially if you happen to get on a bad project.
