Pros
Friendly environment. An open culture with a fair amount of latitude to get involved outside of your own bubble, if you've got the drive for it. Fairly autonomous work environment, at least on the individual scale. It's not a bum-in-seat, 9-5 sort of place. Supervisor while I was there was very good about realizing you have a life outside of work that sometimes has to be managed. So long as you don't take advantage, there's a fair bit of latitude to be able to organise the how and when of your work. Big positive. Office was a relatively standard open-office affair, if not a bit more spacious than most. Normally quiet enough, although a decently expensive pair of noise cancelers wouldn't go amiss if you're the sort of person who, like me, finds it difficult to focus in an open environment
Cons
Decision making seemed to me to be quite top down, and quite sales-driven, meaning that, to my eye, essential technical priorities/opportunities were often left by the wayside in order to achieve short term targets. The long term technical implications of this concerned me. Related, a developer often finds themselves the "point-person" on a wide array of projects, products and features. While appealing to some degree, this did cause me some frustration as the ambitious project-scope often left me with the impression that I wasn't delivering to a level of quality that I was personally happy with, as there was always the pressure to ship and pivot onto the next thing.
