Vantaggi
The changes over the past year or so have been remarkably positive for the most part - there is a clearer sense of direction, focus and leadership. The structure of the company is pretty flat - all of the executives are friendly, involved, and approachable (which is a significant change from the past). Furthermore, Engine Yard is a great place to grow your career. Employees are generally encouraged to manage themselves and there's a lot of opportunity to identify and work on projects of your choosing (whether it's to develop your career or you've identified an opportunity for the company).
Svantaggi
General start up cons - thing can change quickly and sometimes it takes effort to stay informed. Sometimes there's too little process involved and sometimes too much.
