I don’t know of any Waymo presence but Google LA is moving in a couple years to a bigger space and may keep the current offices to house other bets like Waymo. Maybe. As in, the idea was floated but nobody will know what’s going to happen for sure for some time.
They have some radar guys in LA
I'm not sure if it's available on demand. If you're coming to Waymo, I'd expect to work in MTV or SF.
I’m sure you can potentially ask to work out of the google offices in LA..
On the contrary, one of the big contentions in Google lately is that you can’t do this sort of thing. Internal mobility? Great. Work at an office not collocated with your team? Negative. (With exceptions.)
