No - if you signed the bond it doesn't matter whether you have a job or not - or whether the bondsman asked you if you did. You are liable as surety on the bond - having a job or not has nothing to do with your liability. Sorry.
In California, a bail bondsman typically has six months to find and return the defendant. If the defendant is not found in the timeframe, you will be responsible for paying not only the full amount of the bond, but also any additional expenses and any unpaid premiums.
