Pros
Docusign has the benefits of top tech companies as well as the benefits of a smaller companies. There is the challenging and stimulating nature of the work that comes with a strong technical company. There is also very good compensation, with high base salary, all medical/dental/vision premiums paid, 4 weeks vacation, RSUs, free stocked kitchens, and more. But why work for Docusign over one of the larger tech giants like Google or Facebook? The answer is that Docusign is still a young company. There's room for much more impact on the growth of the company. There's more freedom, and quite simply a fantastic work-life balance that seems to have escaped tech giants.
Cons
Docusigns future is not necessarily as stable, considering how there is currently no CEO, and there is a desire to go public. The company could be bought out and changed, which can be scary to some. However, since most of the current investors seem to be quite reputable companies like Google and Apple, I would argue that Docusign is still quite a safe bet.
