Pros
If you are the kind of person that wants to work on cutting edge technology and contribute, this is the best company for you. Compensation & bonus are generous. Health insurance is top notch. ViaSat has unlimited sick days, this shows how much ViaSat trusts their employees in not abusing sick days. I am a through and through technologist and ViaSat, Antenna Systems has been very satisfying to work for. I asked them for $1.5M+ research fund, right after I started working for AS, to develop new technology, and they put their faith in a new employee like me to develop it and their trust in me made me work hard and deliver results. I really think this company has a great future, as long as Mark is at the helm.
Cons
ViaSat being a big company has a bit more red tape than I am used to, but understandable as ViaSat is a big company that deals with government contracts. I came from a very small company, where I wore different hats as the situation demanded, but here I feel a bit restricted. But then again I am NOT working 60+ hours like I did in my previous employment.
