Pros
Engine Yard is filled to the brim with sharp engineers who represent the top talent in their fields. Every single day was an opportunity to learn from the best. For someone who loves learning new things like me, the range of expertise at Engine Yard could not be beat. The culture was slightly on the laid back side compared to the average tech company, but only slightly. I was never bored and always had plenty to do, and middle managers were permissive when it came to extending deadlines in order to get the job done right. I felt that my professional opinion was respected here.
Cons
The company seems to be plagued by years of making sharp changes in direction. They're a bit of a dinosaur in the cloud services provider space and I think that causes some insecurity among the company's top leadership. There is also a history of layoffs which continually repeats itself. I can't speak highly of Engine Yard's track record for job security.
