job opportunities

Yes they do via naukri and LinkedIn. Update naukri to add Dubai as location you're interested to work in, get referrals into talabat, careem, noon, Amazon since you're looking specifically for tech. Zomato only hires via employee referrals

Some companies are recruiting from India. Couple of years back Talabat had reached out via linkedin while I was working in Bangalore. I didn’t proceed with the proposal, but someone in my extended circle got through. Try reaching out to recruiters here on in dubai first. Let them at least save your profile for future reference.

Many. Search LinkedIn. They're often looking for specific skillsets though, like Golang developers. I've received interview requests from Dubai even during the worst time in tech job market.
