Pros
If you want to be part of a team pushing the envelope in bringing new technology to market, this is the company for you. Like most good tech start-ups, Avere has a fast-paced development cycle that doesn't get bogged down in minutiae or politics.
The engineering team is top-notch and most have done this before. In addition, this is the founding CEO's third company, so not only is he not learning the ropes of building a company, but is passionate about the technology as well.
Company and team is well respected in the storage industry and has the backing of Silicon Valley VCs, a rarity in Pittsburgh.
Cons
Don't expect a glamorous facility, company HQ is located in suburban office building that has basic office decor with no frills.
It's a start-up, so if you can't or won't put maximum effort into your work, this would not be the environment for you (nor good for the company).
Company provides tons of free junk food/snacks - the breakroom looks like you stumbled into a convenience store. So if you like to eat healthy, you have to bring your own.
