Pros
Sage is a decent place to work. They are a large company going through a reshuffling of priorities which makes it stressful at times. However, individual business units do operate somewhat independently and until recently felt somewhat autonomous. They are striving to centralize as many processes and technologies as possible though, and that has made it feel a little more "corporate". Co-workers are smart, and friendly. They also support tele-work/remote work and are very supportive of a good work/life balance.
Cons
As mentioned, it's a large company trying to centralize as much as possible. As a result, some software product lines have been sold off, or identified as potential sell-off candidates which has resulted in lay-offs and lowering morale. Increasing pressure to be one brand makes it feel as if some of the autonomy enjoyed by business units/product lines is going to be a thing of the past. Salaries are slightly lower than average, and there haven't been wage increases for about 3 years now.
