Pros
Nice physical building, nice workout fields, decent cafeteria.
Cons
I have worked on a number of programs in Raytheon El Segundo for over three years. Unfortunately, I found the company overall to be led by incapable leadership, treating its engineers as instruments in its business model. This place used to be innovative when it was Hughes Aircraft Company. It is now driven by cost-cutting. There used to be a library, which is now in the process of being closed. It reflects the change in values of the organization. Many of the managers I experienced were technically incapable and failing in leadership. The place is heavy with politics and backstabbing. Engineers are often stuffed in loud cubical farms. Funds are remarkably unstable and management, lacking in technical skills and understanding, often just drives schedule, overlooking and ignoring substantial technical failings.
