Pros
I was able to pick up some very rewarding and challenging work. You are very much trusted to get on with your work and apply yourself. Engineers are usually very keen to share their knowledge with you, I have learned a great deal from my colleagues. There are good opportunities for travel. Design engineers are expected to take responsibility for their work all the way onto site. There's no set pathway for new hires. Some will see this as a con, but I really benefited from it. I was able to choose what path I wanted to take (within the confines of what was available to me obviously).
Cons
Some people find the lack of organised training difficult (i don't include myself in this). Engineers from the UK will not be working on design of robotics, just tooling. It's possible that some design work for robotics will be coming to the UK in the not too distant future. Also there's plenty of work on the robots in support and installation roles.
