No-nonsense startup team with skilled people with varied (and specialized) knowledge.
Varied scope of available work, lots of potential places to improve our product. Very long leash about picking the proper approach to solving problems.
I've only been with the company for a short while, but the leadership is fairly hands on, while managing to be non-intrusive. I feel that the leadership stack is empowered to make good decisions without undue micro-management from higher levels.
