Vantaggi
Everyone there loves what they're doing. You will probably never find another place so full of people who love their jobs so much. That alone makes it a cool culture. There are a lot of innovations and very cool things to work on from the mechanical to electrical to software.
Svantaggi
They aren't the most software-friendly environment. The founders were mostly mechanical in disciplines, so software scheduling is sometimes a little bizarre. Software decisions are often made on history, not necessarily what's good going forward and you end up stuck with those decisions (as does the company). Overall, they have the worst IT support on the planet. The individual workers are really good, positive and helpful, but the structure is horrific. Makes the environment limiting and difficult to get technical things done. Too bad, because the team on the ground is high-quality.
