No, you cannot work in Dubai on a visit or tourist visa. Employing in Dubai under a visit or tourist visa remains against the law. All Dubai workers need to secure a proper work visa which their employer sponsors to maintain legal employment status. Anyone who breaks this regulation will face financial penalties along with deportation and possible exclusion from future entry into the country. Once you locate employment during your visit visa stay your employer should request a work permit which leads to a residence visa conversion before you can start your job.
