Pros
US office is well managed and a force to be reckoned with. Great coworkers and environment to develop and gain many experiences.
Cons
It's hard for me to find cons in the company itself but there is sometimes miscommunication between US and German office sometimes. Since US subsidiary is relatively new in terms of the longevity of the entire company, the engineers in US office might be held in a little less regard and their work looked upon with more scrutiny. Other than that, management is usually aware of this and helps the guys along if needed.
