Pros
The people I work with are some of the best professionally and personally, I have ever met. They are brilliant, clever, thoughtful, and consistently act without hubris, nor do they attempt to save face in light of a mistake. Owning the damage an error may cause is treated as a learning opportunity. As the company is a startup, the ability for a person to interact with a person from every department to resolve some issue or meet the expectations of a partner is common. This is the best opportunity to learn and gain an understanding of how the business works, from the conference, calls with the partner's admin on the phone, to a quick meeting with the account manager(s) to clarify a partner's request. The engineering meetings are very informative and detailed. middle management and the engineering side of the company is rock solid. Smart competent people are in the places that they should be in to make very real, positive gains.
Cons
The salary for the work is not worth the time. You won't make money above a living salary here. The workload is the heaviest I've ever seen and unending. C-suite managers(Directors) are far removed from the stress of the business.
