I don't know if you have the qualification of certified public accountant. If not, there is no advantage in working part-time in the firm, because you can't sign it. Whether you are qualified to attend the meeting depends on whether there is a way to register, because registration requires two years of auditing work and you can't register part-time. Without registration, there is no right to sign.

If you have the time and energy to work as a part-time chief financial officer and chief accountant in an enterprise, it is exactly what the enterprise needs. Of course, with your professional title and level, it should be no problem. It's just a matter of how your unit handles it.
