Pros
Most people who do the actual work at the company are really nice and dedicated to helping save energy. The San Francisco office is in a great location for commuting and salaries are competitive.
Cons
This is NOT a normal software company. It's a Washington DC-based company that does large scale work for energy utility companies. The management in DC doesn't understand that they're not a software company though-- they think this big, ugly, custom dev shop is a SaaS and pitch it as such. It's not so bad to work at a company like this but it's really frustrating to be told how state of the art you are when you've worked at other places. Also, while the DC office is top notch by DC standards, the San Francisco office is on the low end of the scale for perks, food, setup, etc. Again, this isn't terrible, but the management is constantly telling us how great it is and how we're one of the best places to work.
