The projects and technology are super interesting and it would be really incredible if it worked. You get to wear many hats. The other people who work there are mostly really excellent and interesting humans.
Cons
The company got to a terrible place financially where people were not getting paid on time. The leadership tried to right the ship, but clearly didn't and doesn't not really understand what it would take to be successful in any long-term sense. Part of the business plan just involves getting designs pretty much correct the very first time.
