Pros
One of my favorite things about SnapStream is that the code I write directly influences and helps our clients. It is a great feeling to see a feature I've implemented as the highlight of one of our blog posts or to hear from a colleague about how our clients are excited for it. There are a huge variety of problems to solve and I am not stuck only working on one aspect of our product. Instead I get to do full stack programming and I've learned a ton while doing so. Our senior developers are amazing and are an excellent source of knowledge when Stack Overflow fails to deliver. We have continuous integration, an excellent suite of unit tests, and a top notch QA team. If you have an expertise outside of general programming, SnapStream will try to give projects that can tie your expertise and the SnapStream product together. SnapStream really pampers the developers. I have two 27 inch 1440p monitors, a huge desk, and a high powered PC. Both the hours and the dress code are relaxed. There are snacks in the kitchen and plenty of great places to eat nearby. There is a nice emphasis on fitness. SnapStream provides gym memberships and a weekly personal trainer.
Cons
My computer is too fast to use compiling as an excuse to slack off. On a more serious note, SnapStream has been around for over a decade, but still has that startup feeling. Personally, I really enjoy it, but I know that the startup culture is not for everyone.
