Pros
As a "startup" company (5 years as of 2019) they offer good salaries and the opportunity to work on very interesting problems. The work is intense but the demands a reasonable: nobody expects you to work unreasonable hours for example unless there was an emergency. It offers benefits although the health benefits were not very generous, however the good salary compensated this. Retirement benefits were good, and they offer dental insurance but no vision plan. Share options can be purchased at a lower rate (developers and engineers) but that is "icing on the cake" that should never tilt a decision to join a company.
Cons
The same "startup" mindset meant that they want results fast and they want you to conform for what they expect. Results need to be delivered quickly, there are not enough procedures in place, in other words they are still figuring out how to grow while delivering results quickly. My personal experience (this is not the case for everybody I found out) was that onboarding was lacking and I did not get the required attention and help I needed to learn the software that was being developed. In the end I discovered that it was a bad fit, which made me feel confused about what they hired me in the first place. In my opinion their expectations did align to what I could provide to the company. In terms of management they made the mistake of equating engineering brilliance with good management material, that is sometimes a mistake. This was my bad luck but also a reflection of their lack of management experience. Your mileage may vary and you may fit perfectly which explains the tile of this review.
