Pros
Good weather and location. This is a tech company and the culture is overwhelmingly techie. The scientists are genuinely motivated by the technology.
Cons
Too many VP's. Most of them are uninspiring and full of platitudes. No real career path. HR is non-supportive with most requests. Performance reviews aren't put to any real use. The technology isn't easily transferable. You might have trouble landing your next job if you want to do something else. Company is relatively unknown outside the industry. The technology moves so fast that there is little or no process to anything. Their lasers often break down in the field, and since almost nobody in the entire company understands the entire system, everyone is constantly in panic mode. Highly cyclical industry. Layoffs are commonplace here.
