, you would need a visa/extension based on marriage to get a Ministry of Labour office to issue a work permit, you would need to make xxx baht a month in salary the company would have the have the correct number of LEGAL thai employees that they're paying thai social security on and deducting withholding taxes.
I'll leave it to you to imagine the sh*t-storm that could happen if you were caught out working on the wrong visa and without a work permit..
