Pros
After having spent years at a gigantic software company, I greatly cherish the influence and scope of work that I have now at DocuSign. It's about "just right" size where you have support and a full set of corporate services like IT, HR, facilities, etc but small enough that when you see a problem that needs addressed, you can very often become a champion to solve that issue without having to check with 20 people first. You end up solving the problem at many or every level in which it needs to be addressed, which is incredibly rewarding.
DocuSign is also a fairly flexible work environment for engineers, coming up with creative schedules, processes and locations for you to achieve your goals.
Finally, DocuSign is very exciting right now because our new CEO has been on board for just long enough to really have a grasp of everything and is starting to make the big moves we hoped the company would make for it's future. Will we IPO soon? Don't ask me, but it sure seems like we've been closer than ever in the 3+ years I have worked here.
Finally, it is a company that cares about it's employees and the communities in which we live. They have a matching gifts IMPACT program for non profits, plus continually add better and better benefits to support all sorts of workers with different abilities and life constraints. Recent changes to family leave, for example , were very generous. Diversity and gender equity are more than just checkboxes on a list here. They really seem to mean it.
Cons
Split between Seattle and San Francisco headquarters still has some division in ways teams work, style, process and leadership. I think with new leaders these things are starting to be ironed out, but it has caused a slow in delivery of some key things, IMHO.
