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.
When bail is exonerated it means you or the bail bondsman gets their deposit back from the court clerk. When the defendant is exonerated, it means the charges are dropped and the defendant is no longer suspected of any wrongdoing. Last but not least, it is possible for bail exonerations to be denied.
The Bail Reform Act gives a criminal defendant a right to request a lower bail if the amount set by the court initially is too high. At the bail reduction hearing, the defendant is able to argue that the bail set is so high that it is effectually the denial of bail and thus it should be reduced.
Post-conviction bail is usually not available after convictions of serious or violent crimes, but some jurisdictions allow post-conviction bail when a defendant's sentence is shorter than the amount of time that it would likely take to resolve the appeal.
