Need Help Setting Up Hiring Indicators for Singapore Companies

Hi guys, Looking for some help, I am trying to set up a clay table and set it up with some indicators that the company is hiring in Singapore. I have pulled a list from Crunchbase of venture backed UK companies, the list has the URL, Linkedin ULR, Description and all that; but I don’t know how do I create an enrichment to tell me if they are hiring in Singapore. Can someone please help me?
