Pros
The biggest reason I would join again is that the company is currently growing fast and there is lots of room for you to grow into whatever role and job type you want. If you are a recent grad most positions at this company would be ideal to get your foot in the door and become the kind of engineer you want. People at the company are friendly and helpful creating a relaxed work environment despite the overwhelming amount of things to do. Everybody is willing to step in and help at a moments notice. Management also is more in touch with what is actually happening than many places I have worked, which helps.
Cons
The pay is somewhat less than elsewhere in the industry, Depending on the position there may be lots of travel, which tends to wear people out after a few years.
