That base is too low to consider for that position (Also, what is the strike price of the options?). I don't know your personal situation and how badly you need the job but even outside of silicon valley I think it's low and would not consider anything less than 100k. If you can stand to walk away I'd counter with 120k at least. Recruter friends of mine are placing people at 120-150k all the time for that role here in California. Ping me via email if you want to chat off list.
EDIT: If they can't afford to pay market rates and you really really like the company then they need to come legit with serious equity but I would never play that game. Market rates or GTFO.
