Pros
The people and culture are the absolute best that I've been exposed to in my career. The technology delivers an obvious value, and is supported by an organization unlike any I've ever worked for. My first exposure to the company was spending some time with the CEO and he actually offered up some career advice and suggestions for other organizations if I decided that Pure wasn't for me. This is the single most dedicated and honest leadership team in the business today period. To say that they care about their employees is a huge understatement. Companies live and die by leadership alone, regardless of their products, and Pure Storage obviously has the best of both.
Cons
The fast paced business of a small post start-up company is not for everyone. There are some procedural tasks that are in development, so relying on your own creativity to accomplish tasks is sometimes a requirement. Things also change very rapidly, and you could have 10 new neighbors next week. If you do not like meeting new people on a regular basis, this is probably not the place for you. If you are inspired by working very hard and reaping the rewards, you are a perfect fit.
