Raja, yes. Few MNCs have Health care projects. They need Medical professionals for these projects. These projects might be Insurance, Medical device, Coding related. These projects are usually headed by Medical Professionals like licensed Doctors, Paramedics and Nurses. So to answer your question, MNCs require Doctors for their projects. Apart from that every MNC will have a Panel Doctor in its campus for emergency requirement of its employees.

Raja Ram, software companies don't generally hire doctors. They might be hired for the medial health center inside the office premises (if one is available). Other than that, they might be hired if the software company works in the field of healthcare facilities- they develop platforms for doctors and patients or develop fitness equipments, etc. Here doctors may help to test the end products. Otherwise software companies would not require doctors.
