Synacor has a very realistic environment. We have realistic goals and realistic timetables with realistic resources to get things done. We aren't slow but we also don't work 100-hour weeks to get yet another thing done too fast with tool little. Realism also leads to quality.
As an engineer, I'm impressed with how knowledgeable about engineering the senior management is. I feel like a valued team member who delivers business results, not an asset to be expended to make a couple of things. Even the CEO knows what I do and how things work!
I like being at a company where everyone's trying to help everyone else succeed. I've never reached out to someone at another team who hasn't gone out of their way to educate me, give me the information or resources I need, and been happy to talk to me again.
