Does the non-compete clause restrict working with competitor under different designation?

I have been working at a company for nearly 3 years under an unlimited labor contract as a Software Engineer, but the labor contract states that I am working in sales.

The contract states that I am not allowed to work for a competitor for a period of 2 years in the UAE. I have got a job offer from a competitor with almost double the salary.

The job offer is as a Software engineer. Will the non-compete clause be valid keeping in mind that the new job does not match my labor contract role?

If yes, can the old employer prevent me (ban) from moving to the new role and can they file a law case?
