Pros
To say that Tanium is not your average company is a gross understatement. Tanium is by far the most challenging, high op-tempo environment I've ever seen. It's also the most positive environment I've ever worked in. The company is highly technologist focused. That is to say, it's not the sales org around which Tanium builds its culture, but rather the technical organization. That's not to say that Sales isn't respected, just that it's not the normal "I'm the sales guy, where's my SE!!!" dynamic. You'll find that the technical folks and the sales folks have a deep mutual respect. Tanium does not employ "SEs". The technical account managers (TAMs) are hard core engineers for the most part, but you won't find a prima donna among them (if you do, you'll likely find them headed out the door with a hearty "good bye" from their peers). That's another great aspect; no drama. Tanium employs adults, and what do you know, adults can pretty much get along, manage themselves and be productive out of the sheer joy of producing something meaningful. It's really an incredible place. I can't say how fortunate I consider myself to work here. I've been in the cyber-security and engineering world for about 25 years and this place is just light years ahead of every other place I've been.
Cons
The hours can be long, but I do that to myself. My position requires constant travel, but I knew that getting into it and it's a calculated investment. The only real con I can think of over the past few years that I've been here is perhaps a lack of bacon in the early days. Fortunately, that has been remedied of late.
