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.
If your warrant is set at no bond, technically that means you will not be able to bond out, but a knowledgeable attorney may be able to negotiate with the prosecutors who are handling the case along with the judge and get them to agree to set a bond. You will be arrested.
