Pros
Great pay for entry-level job. There are opportunities to move around and learn new things as a junior non-software engineer, Software engineers can also move around, but the vast majority of software opportunities are to maintain code from the 80s, build bad code fast, or move files. Company respected work-life balance and flexible hours.
Cons
In the Boulder, CO location in particular (I did not encounter this issue at the Aurora and Colorado Springs locations), there is a refusual to fire senior engineers who work from home and refuse to come into the office or maintain an online presence. They are held unaccountable for not fulfilling their responsibilities and using junior engineers to perform their own menial tasks in the classified environment so that they do not need to either come into the office. As much as they claim to be transitioning to Agile, software at Northrop Grumman is monolithic, messy, and completely undocumented. There is a complete lack of interest in developing quality code or maintaining software best practices. Work in software for Northrop and you will leave without transferable skills to develop software at another company.
