Yes. A subsidiary 100% owned by a Korean parent company is the same as any other Singapore company, so it must appoint a company secretary who meets the local residency requirement within 6 months of the date of incorporation.
The company secretary must be an individual, and in a company with only one director, that director cannot also act as the company secretary.
Lee Kim Alliance provides a company secretary service.
