Are you looking outside USA too? In Europe maybe?
It's on the original post that they are only looking for those people that are located only on or near San Francisco.
Unfortunately we cannot do remote work at this point, so you need to be local to SF.
At first I have a big interest to join their team while reading the first sentence but on the next sentences I lose my interest because I'm not near to their place. But if they have any other job offers for those people that can work for them remotely you can hit me up with your qualifications and requirements.
