Pros
If you're serious about working with a hard-charging company that is continually trying to innovate Tanium is a great company. There are some of the brightest developers and top IR specialists that are trying to change how the industry approaches security and operations. The company definitely values innovation by empowering the engineers. Something a bit different on the engineering side of things is the flat organizational structure as there are only a couple of levels between an engineer and the CEO. This is a good thing for those of us who aren't working for a title and just like to do our job. We are well compensated and treated like adults trying to create great tech. For anyone who has been in the startup world for a bit you have definitely weathered through some bad CEOs. Part of the reason for coming to Tanium was the experience and leadership that the Hindawi's brought to the table. Without the experience they have brought to the table rarely do you see companies achieve what they have in such a short amount of time.
Kontras
The biggest con is things are moving fast and, like most startups, there is no shortage of work. It is really incumbent upon yourself to step back as needed.
