I do not understand what do you mean by headline: opiniones de empleados con el puesto de Manager en Advanced Infrastructure Design

I'm part owner. Environment is friendly and we deal with high tech facilities

None. I cannot say that there is any cons associated with this

As a small firm, the management are very friendly, caring and supportive. The company is very specialized in NDE and pavement design. One could get involved in different tasks within the company work areas.

Not much honestly. There are shortcomings but such problems exists in any firm of this size and it is not specific to AID.
