Pros
Team is very easy to get along with. Never any interpersonal issues and everyone tries to help each other out.
Good company benefits.
Expectations are set reasonably. You will not be crushed by your workload but you will be challenged.
The president of the company is reasonable, friendly, and good at what he does. He makes sure all of the gears are moving in synch.
The company is doing well already and appears to be moving even more in the right direction.
Cons
A lot of your work will be done in proprietary software so the knowledge gained may not necessarily transfer to another company.
