Pros
Anki is an amazing place work with really high quality people and always an opportunity to learn. It's part robotics start up, consumer electronics company, part toy company, part video game studio, part animation studio. I don't know anywhere else you could find this diversity of skills and interests all working on the same products. Unlike so many other robotics companies I've been part of or close to, Anki understand customer centered design and that to be successful a robot has to be a product, not just a neat platform.
Cons
Being in San Francisco you're stuck with either outrageous housing costs or a long commute. But at least it's central. Anki isn't a start up but it still operates very lean so be prepared for crunch times occasionally.
