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 a defendant cannot afford bail, then at the arraignment or any hearing while still incarcerated the defendant can request a bail reduction or release without bail. That must be supported with evidence that the defendant is unlikely to reoffend or to flee.
