Pay it would be the best and probably only way.
If a warrant has been issued, the police have no choice but to execute the warrant. I suggest you or your solicitor contact the procurator fiscal and get agreement to pay the fine to the court immediately. The only way to have the warrant withdrawn is via the PF. I appreciate your concern about your job but you may have to give this priority to avoid being taken into custody.
You can do that but my answer was designed to avoid that.
I would still try to do this via your solicitor and the PF. The PF has the power to countermand the warrant. The police don't, as you have seen.
