Despite the pros, DocuSign is a terrible place to work, with very little management involvement until something goes wrong. Parts of engineering are allowed to be abusive and offensive simply because they deliver quality work, and 'brogrammers' are everywhere. Office politics is present, and there is a very real 'old boys network' in place. If you want to succeed, you better hitch your boat to one of the established cliques, and be very careful how you tread. Upper management is sometimes completely clueless about what is actually going on at an operational level. (Or perhaps they have a little of the 'Steve Jobs reality distortion field' in effect, it can be hard to tell the difference)
Ultimately, stay away from Docusign, because your career there will be like a trip through a mine field: You wont know if you made a misstep until its too late.
