Pros

Great benefits, including health benefits, 401K, wellness program, and HSA. This position doesn't require on call, but often time need to work until late night if there is any tool issues showed up.

Cons

This is a satellite office to serve the big customer in Hillsboro Oregon. Thus, this place didn't provide much activities and events as the headquarter. This position requires someone having deep understanding of the tool, so not recommend for newly graduated people. This position also needs to have frequent meeting with R&D Engineers, otherwise you will not have answers for all sorts of questions. This position only have very limited chance for career grow.
